An ultra high pressure pump is an industrial plunger pump designed to produce a highly concentrated water stream for demanding cleaning, surface preparation, material removal, cutting, and demolition work. Unlike standard cleaning equipment, it is built for applications where dirt, corrosion, thick coatings, scale, concrete, or industrial deposits cannot be removed efficiently with conventional pressure washing.
These systems use a motor or diesel engine to drive a plunger pump, which pressurises water and delivers it through high-pressure hoses, guns, lances, and nozzles. Depending on the application, an ultra high pressure pump may operate at around 1,000 bar, 1,500 bar, or up to 2,800 bar. Fussen’s FRE electric and FKD diesel ultra-high-pressure systems are designed for this type of intensive industrial work.
| Equipment Type | Typical Purpose | Suitable Applications |
|---|---|---|
| Standard pressure washer | Routine surface cleaning | Vehicles, property maintenance, light equipment, farm cleaning |
| Industrial high pressure washer | Heavy-duty cleaning and maintenance | Factory floors, machinery, ship cleaning, road cleaning, rust removal |
| Ultra high pressure pump system | Intensive material removal and specialist water jet work | Hydroblasting, coating stripping, concrete removal, tank cleaning, surface preparation, water jet cutting |
The main difference is not only the maximum pressure rating. Pressure helps break the bond between contamination and the surface, such as rust, paint, scale, grease, concrete, or marine growth. However, flow rate is equally important because it carries away the loosened material and determines how quickly a large area can be cleaned.
For example, a system with very high pressure but insufficient flow may remove a coating in a narrow area but work slowly across a large surface. A properly matched ultra high pressure pump combines the right pressure, flow rate, nozzle, and operating method to achieve both removal power and cleaning productivity.
For industrial buyers, the right question is not simply, “What is the highest bar available?” It is: What pressure and flow combination is required for the material, surface area, working environment, and daily operating hours of the project?
Industrial water jet equipment is often described by its working pressure in bar или ПСИ. One bar equals approximately 14,5 PSI, so a 1,000 bar pump produces around 14,500 PSI, while a 2,800 bar pump reaches approximately 40,000 PSI.
There is no single global threshold that every manufacturer uses for the term “ultra high pressure.” In practical industrial cleaning and water jetting applications, systems from around 1,000 bar upward are commonly considered ultra-high-pressure equipment. However, the correct pressure depends on the material being removed, the surface condition, the required cleaning speed, and the risk of damaging the substrate.
| Диапазон давления | Approximate PSI | Typical Use |
|---|---|---|
| 500–800 bar | 7,250–11,600 PSI | Heavy industrial cleaning, thick deposits, coating preparation, machinery cleaning |
| 1,000 bar | 14,500 PSI | Rust removal, tank cleaning, surface preparation, industrial maintenance |
| 1,400–1,500 bar | 20,300–21,755 PSI | Hydroblasting, stronger coating removal, marine maintenance, heavy industrial cleaning |
| 2,000–2,800 bar | 29,000–40,000 PSI | Ultra-high-pressure cleaning, concrete removal, specialist water jet work, demanding material removal |
A higher pressure rating does not automatically mean a better solution. For example, a 2,800 bar pump may be appropriate for specialist concrete removal or difficult coating stripping, but it may be excessive for routine tank cleaning or general rust removal. Using more pressure than necessary can increase energy consumption, accelerate wear on nozzles and hoses, and create a greater risk of surface damage.
For this reason, buyers should evaluate pressure together with flow rate. Pressure provides the impact needed to break the bond between the surface and the unwanted material. Flow rate determines how much water is available to flush away the loosened debris and how quickly the operator can complete a large cleaning area.
Fussen provides ultra-high-pressure systems from 1,000 bar to 2,800 bar. The электрический Серия FRE includes the FRE 120/100, FRE 90/140, FRE 50/150, and FRE 45/280 models, while the diesel-powered Серия ФКД offers corresponding options for mobile and remote job sites. This gives industrial users the flexibility to select the right pressure and power source for ship cleaning, hydroblasting, industrial maintenance, surface preparation, concrete removal, and other specialist water jet applications.


Ultra high pressure pumps are used where conventional cleaning equipment cannot remove heavy contamination, thick coatings, corrosion, scale, concrete, or industrial residues efficiently. Their value is not simply high pressure; it is the ability to deliver controlled water jet power for demanding maintenance, surface preparation, and material-removal tasks.
For buyers, the right system depends on the job site, the material being removed, the size of the work area, available power supply, water source, operating hours, and safety requirements.
Shipyards, ports, offshore service companies, and marine maintenance contractors use ultra high pressure pumps for hull cleaning, rust removal, coating preparation, and cleaning large marine structures.
Типичные области применения включают:
Refineries, petrochemical plants, chemical processing facilities, and oil and gas service contractors often require high-performance water jet systems for shutdown maintenance and difficult cleaning tasks.
Ultra high pressure pumps can be used for:
These projects often involve strict safety procedures, limited access areas, continuous operation requirements, and highly demanding cleaning conditions. Buyers may need to consider not only pressure and flow rate, but also hose length, nozzle type, filtration, water supply, remote operation options, and whether explosion-proof equipment is required for the working zone.
Industrial cleaning contractors are one of the most important user groups for ultra high pressure pumps because they work across multiple sites and must handle different cleaning challenges.
Typical jobs include:
For contractors, flexibility is especially important. They may require a mobile diesel system for outdoor or remote work, while larger fixed projects may benefit from an electric system with a stable water supply and continuous-duty configuration.
Ultra high pressure water jetting is widely used in construction, bridge maintenance, concrete repair, and infrastructure rehabilitation.
К распространенным областям применения относятся:
Unlike mechanical demolition methods, water jetting can remove deteriorated concrete while helping preserve sound concrete and reinforcement steel when the correct pressure, flow rate, and nozzle configuration are selected. These applications often require high-output systems, robust hoses, specialist lances, and strict operator safety procedures.
Railway operators, maintenance contractors, fleet service companies, and transportation authorities use ultra high pressure pumps to clean equipment and maintain infrastructure.
Applications may include:
For large-scale fleet or depot cleaning, electric systems may be preferred where power is available. Diesel systems are more suitable for mobile maintenance teams working along rail lines, at remote depots, or on infrastructure projects.
Municipal sanitation departments, public works contractors, and urban maintenance teams use high-pressure water jet equipment to maintain public infrastructure and improve cleaning efficiency.
Типичные области применения включают:
For municipal projects, mobility, ease of operation, water tank capacity, and reliable long-duration performance are often as important as maximum pressure.
Steel plants, cement plants, power facilities, automotive factories, foundries, and other heavy manufacturing sites use ultra high pressure pumps for maintenance, cleaning, and production support.
Typical uses include:
These facilities often require dependable equipment that can operate repeatedly in dusty, hot, wet, or corrosive environments. Buyers may prioritise durable plunger pumps, high-quality seals, stable water supply, low-water protection, easy maintenance access, and compatibility with specialist accessories.
Across these industries, Fussen can support different operating conditions with electric Серия FRE ultra high pressure systems for fixed industrial sites and diesel Серия ФКД systems for mobile, outdoor, and remote applications. The final configuration should be selected according to the cleaning task, required pressure and flow rate, power source, site environment, and safety requirements.
An ultra high pressure plunger pump converts mechanical power from an electric motor or diesel engine into a controlled, high-energy water jet. Although the system may look complex, its working principle follows a clear process: water is supplied, pressurised by plungers, controlled through safety components, and delivered to the cleaning or cutting tool.
The process begins with a reliable water source. Water may come directly from a supply line, an onboard water tank, or a separate water storage system. Before entering the pump, it passes through high-precision filters that remove particles and impurities.
Clean water is essential because abrasive particles can damage plungers, seals, valves, and nozzles. For larger or continuous-duty systems, a booster pump and float valve may also be used to maintain a stable water supply and prevent dry running.
An electric motor or diesel engine provides the power needed to operate the pump. This power is transferred through a coupling, gearbox, or crankshaft mechanism to the plunger assembly.
Electric-driven systems are commonly selected for fixed industrial sites with stable power supply, such as factories, shipyards, and maintenance workshops. Diesel-driven systems are better suited to remote projects, ports, construction sites, and mobile industrial cleaning work where electricity may not be available.
Inside the pump, the crankshaft moves the plungers back and forth. During the suction stroke, water enters the pump chamber through inlet valves. During the compression stroke, the plungers force the water through outlet valves at extremely high pressure.
The plunger material is critical because it operates under constant friction, pressure, and exposure to water.
Fussen uses different plunger materials according to the operating condition:
After water is pressurised, several components help keep the system stable and safe.
These may include:
These components are important because ultra high pressure water jetting requires stable output. Sudden pressure fluctuations, insufficient water supply, blocked nozzles, or worn seals can affect cleaning performance and increase equipment wear.
Once pressurised, water travels through a high-pressure hose to the working tool. Depending on the application, operators may use a high-pressure gun, dump gun, flexible lance, rotating nozzle, fan-shaped nozzle, or pipe-cleaning nozzle.
The nozzle converts pressurised water into a focused jet pattern. A narrow jet may be used for concentrated removal of rust, coatings, or hardened deposits, while rotating or fan-shaped nozzles can cover larger areas more efficiently.
The final cleaning result depends on the complete system—not only the pump. Pressure, flow rate, nozzle size, spray angle, hose length, water quality, and operator technique all influence performance.
For demanding environments, Fussen can also provide customised seal solutions with improved corrosion resistance or high-temperature resistance. This helps customers configure ultra high pressure pump systems for marine, petrochemical, heavy manufacturing, and other challenging industrial applications.
Choosing an ultra high pressure pump should begin with the job, not the highest available pressure rating. A system that is too small may not remove the required material efficiently, while an oversized system can increase capital cost, energy consumption, maintenance requirements, and the risk of damaging the surface.
The right configuration balances pressure, flow rate, power source, duty cycle, water supply, mobility, accessories, and site safety requirements.
| Selection Factor | What to Consider | Why It Matters |
|---|---|---|
| Required pressure | Identify the material to be removed: rust, scale, coating, marine growth, concrete, or hardened process deposits. | Pressure provides the impact needed to break the bond between unwanted material and the surface. |
| Скорость потока | Consider the area to be cleaned, required completion time, and amount of debris to be removed. | Flow rate carries away loosened material and has a major effect on cleaning productivity. |
| Power source | Choose electric power for fixed facilities with stable electricity, or diesel power for remote, mobile, port-side, and construction work. | The power source affects mobility, operating environment, installation requirements, and daily operating cost. |
| Duty cycle | Define whether the pump will be used occasionally, during scheduled shutdowns, or for long continuous shifts. | Continuous-duty applications require more robust pump components, cooling, water supply, and maintenance planning. |
| Water quality and supply | Check water availability, inlet pressure, filtration requirements, tank capacity, and whether a booster pump is needed. | Poor water quality or unstable supply can damage seals, valves, plungers, and nozzles, while dry running can seriously damage the pump. |
| Operating environment | Consider saltwater exposure, humidity, dust, heat, corrosive residues, confined spaces, and hazardous zones. | The frame, pump materials, seals, motor protection, and safety configuration should match the environment. |
| Mobility and installation | Decide whether the system should be trolley-mounted, skid-mounted, trailer-mounted, containerised, or installed permanently. | The right layout improves access, transport efficiency, operator safety, and job-site productivity. |
| Аксессуары | Select suitable hoses, guns, lances, nozzles, hose reels, foot valves, and filtration equipment. | The pump cannot perform at its full potential if accessories are incorrectly rated or unsuitable for the application. |
| Требования безопасности | Review pressure relief devices, safety valves, bursting discs, emergency shutdown, hose protection, PPE, and operator training. | Ultra high pressure water jetting requires a complete safety system, not only a high-pressure pump. |
| Maintenance and service | Check spare parts availability, seal replacement access, filter maintenance, lubrication requirements, and technical support. | A maintainable system reduces downtime and helps protect long-term operating cost. |
The first question is: What needs to be removed, and what surface must remain after cleaning?
For example, removing loose rust from a steel structure requires a different configuration from stripping thick marine coatings, cleaning refinery deposits, or selectively removing damaged concrete. The operator must also consider whether the underlying surface is steel, concrete, composite material, stone, or another sensitive substrate.
A suitable system should deliver enough water jet energy to complete the task efficiently without causing unnecessary substrate damage.
Pressure and flow rate should always be evaluated as a pair.
A high-pressure, low-flow system may be effective for precise removal in a narrow area. A higher-flow system may be more productive for large-scale ship cleaning, tank cleaning, or industrial surface preparation. The best choice depends on both removal difficulty and project productivity targets.
Electric and diesel ultra high pressure pumps serve different operating conditions.
Electric ultra high pressure pumps are generally suitable for factories, shipyards, workshops, and fixed industrial cleaning stations with reliable power supply. Fussen’s Серия FRE is designed for high-output electric ultra high pressure applications, with models ranging from 1,000 bar to 2,800 bar.
Diesel ultra high pressure pumps are often better suited to construction sites, remote infrastructure projects, ports, outdoor maintenance work, and mobile cleaning contractors. Fussen’s Серия ФКД provides comparable ultra high pressure capability where fixed electricity is unavailable or mobility is a priority.
A pump used for occasional maintenance has different requirements from one operating through a refinery shutdown, shipyard project, or continuous industrial cleaning shift.
For demanding environments, buyers should specify:
Marine and petrochemical projects may need corrosion-resistant materials and customised seals. Construction and remote service projects may require a diesel engine, large water tank, booster pump, hose reel, and rugged mobile frame.
An ultra high pressure pump is only one part of the complete water jetting system. The final configuration should include accessories rated for the selected pressure and flow rate.
Typical requirements include:
For ultra high pressure applications, safety equipment and operator training should be included in the project plan from the beginning. Correct hose routing, nozzle selection, exclusion zones, PPE, emergency shutdown procedures, and routine inspections are essential for safe operation.
To receive an accurate recommendation, buyers should provide:
With this information, Fussen can recommend an appropriate FRE electric or FKD diesel ultra high pressure system and configure the pump, water supply, hose, gun, nozzle, and safety components around the actual job requirement.
The choice between an electric and diesel ultra high pressure pump is usually determined by the job site rather than cleaning performance alone. Both can deliver the pressure and flow needed for demanding water jetting work, but they differ in power availability, mobility, emissions, installation requirements, and operating flexibility.
Fussen offers both options across its ultra high pressure range: the Серия FRE for electric-powered operation and the Серия ФКД for diesel-powered operation. Both series include models from approximately 1,000 bar to 2,800 bar, allowing buyers to select the most suitable power source without compromising the capability required for industrial cleaning, surface preparation, hydroblasting, or specialist water jet work.
| Фактор | Electric Ultra High Pressure Pump | Diesel Ultra High Pressure Pump |
|---|---|---|
| Best operating environment | Factories, shipyards, workshops, fixed cleaning stations | Construction sites, ports, remote projects, outdoor maintenance |
| Power source | Fixed electrical supply | Integrated diesel engine |
| Мобильность | Better for fixed or semi-fixed installations | Better for mobile and field-based work |
| Local emissions | No engine exhaust at the point of use | Produces engine exhaust and requires ventilation |
| Indoor use | More suitable for enclosed or indoor work areas | Usually more suitable for outdoor or well-ventilated areas |
| Noise level | Typically lower and easier to manage | Typically higher due to engine operation |
| Installation | Requires suitable voltage, frequency, and electrical capacity | Requires fuel supply, ventilation, and engine maintenance |
| Typical users | Factories, shipyards, refineries, industrial maintenance teams | Contractors, infrastructure teams, mobile cleaning services, ports |
| Fussen series | Серия FRE | Серия ФКД |
Electric ultra high pressure pumps are best suited to sites with reliable electrical infrastructure and regular cleaning or maintenance requirements. They are commonly used in factories, shipyards, workshops, industrial cleaning stations, and fixed maintenance facilities.
The main advantages of an electric system include:
Он Серия FRE is a practical option for industrial users who need ultra high pressure performance as part of an established facility. It can be configured for applications such as rust removal, tank cleaning, surface preparation, marine maintenance, heavy equipment cleaning, and specialist industrial cleaning.
Electric systems are particularly suitable when the equipment will remain in one location or move only within a defined facility. Buyers should confirm local voltage, frequency, available electrical capacity, cable length, and protection requirements before selecting a model.

Diesel ultra high pressure pumps are designed for projects where fixed electrical power is unavailable, unreliable, or impractical. They are widely used by industrial cleaning contractors, construction companies, port maintenance teams, municipal departments, and infrastructure service providers.
The main advantages of a diesel system include:
Он Серия ФКД is suited to applications such as hydroblasting, concrete surface preparation, road and bridge maintenance, shipyard work, remote tank cleaning, and mobile industrial cleaning.
Because diesel systems produce exhaust emissions and engine noise, they are generally better suited to outdoor or well-ventilated environments. Buyers should also consider fuel availability, routine engine maintenance, local emissions rules, and transport requirements when planning a diesel-powered system.

Choose an electric FRE Series system when:
Choose a diesel FKD Series system when:
In many cases, the pressure requirement may be the same for both options. The decision comes down to how and where the equipment will operate. By offering both FRE electric and FKD diesel ultra high pressure systems, Fussen can help buyers match the power source, pressure level, flow rate, and system configuration to the real conditions of the project.
An ultra high pressure pump is only one part of a complete water jetting system. The accessories connected to the pump determine how safely, efficiently, and accurately the water jet can be used on site.
A correctly matched hose, gun, nozzle, water supply system, and safety component helps the pump maintain stable performance. By contrast, an undersized hose, incorrect nozzle, poor filtration, or inadequate water supply can reduce cleaning productivity, create pressure fluctuations, and shorten the service life of critical pump components.
| Accessory | Main Function | Selection Considerations |
|---|---|---|
| High-pressure hoses | Carry pressurised water from the pump to the working tool | Must be rated above the system’s maximum working pressure and suitable for the required flow rate, temperature, bend radius, and working environment |
| Dump guns | Safely release water flow when the trigger is released or during operator repositioning | Must match the pressure and flow rating; important for operator safety and pump protection |
| Fan форсунки | Produce a flat spray pattern for wider surface coverage | Suitable for surface cleaning, coating preparation, and large-area work; spray angle affects impact force and coverage width |
| Вращающийся форсунки | Create a rotating water jet for stronger cleaning action over a wider area | Useful for rust, scale, coatings, and difficult deposits; should be selected according to pressure, flow, and surface sensitivity |
| Pipe-cleaning форсунки | Direct water jets forward and backward inside pipes, tubes, and drains | Used for pipelines, heat exchangers, drains, and internal cleaning; nozzle size and jet pattern must match pipe diameter and blockage type |
| Гибкие копья | Extend access into confined, curved, elevated, or difficult-to-reach areas | Useful for tanks, vessels, undercarriages, marine structures, and complex equipment layouts |
| Hose reels | Store, protect, and deploy high-pressure hoses efficiently | Improve hose handling, reduce damage, and support faster setup on large sites or mobile systems |
| Foot valves | Allow the operator to control water flow remotely by foot | Helpful for certain stationary cleaning, tank cleaning, and specialist water jetting tasks where hands must remain on the lance or workpiece |
| Booster pumps | Maintain stable inlet water supply to the ultra high pressure pump | Important when the water source has low pressure, long inlet lines, or inconsistent flow; helps prevent cavitation and dry running |
| Water tanks and filtration systems | Store and clean incoming water before it enters the pump | Essential for remote sites, mobile systems, and locations with poor water quality; filtration protects plungers, seals, valves, and nozzles |
High-pressure hoses must be selected according to the pump’s maximum working pressure, flow rate, operating temperature, and application environment. For ultra high pressure systems, every hose, fitting, coupling, and protective cover must be rated for the full operating condition, not only the normal working pressure.
Buyers should also consider:
A hose that is too long, too narrow, damaged, or incorrectly rated can create pressure loss, restrict flow, and increase safety risks.
A dump gun is an important safety and control component in ultra high pressure water jetting. It allows the operator to direct water safely away from the work surface or release pressure when repositioning.
For industrial applications, the dump gun should be selected based on:
For specialised work, Fussen can also configure systems with foot valves, flexible lances, and other operator-control accessories to improve handling and reduce unnecessary downtime.
The nozzle determines how the water jet contacts the surface. Even with the same pump, changing the nozzle can significantly affect impact force, cleaning width, debris removal, and risk of surface damage.
Fan nozzles are suitable for broad, controlled cleaning of large surfaces. They are commonly used for surface preparation, general industrial cleaning, and coating removal where a wider coverage pattern is required.
Вращающиеся форсунки combine concentrated impact with circular coverage. They are often used for heavy rust, scale, hardened deposits, and difficult coatings.
Pipe-cleaning nozzles are designed for internal cleaning. Rear-facing jets help pull the nozzle through the pipe, while forward jets help break through deposits or blockages. They are commonly used for pipelines, drains, tubes, vessels, and heat exchanger cleaning.
The nozzle orifice size must match the pump’s pressure and flow rate. An incorrectly sized nozzle can cause unstable pressure, poor cleaning performance, excessive wear, or unnecessary load on the pump.
Ultra high pressure pumps depend on a stable and clean water supply. Water starvation, contaminated water, or inadequate inlet flow can cause cavitation, seal damage, valve wear, pressure fluctuations, and premature pump failure.
A complete water supply system may include:
For shipyards, construction sites, municipal projects, and remote industrial work, a properly sized water tank and booster pump can be as important as the ultra high pressure pump itself.
The best accessory package depends on the actual job. A shipyard may need long abrasion-resistant hoses, rotating nozzles, flexible lances, and corrosion-resistant fittings. A refinery contractor may need pipe-cleaning nozzles, specialist hoses, filtration, and safety-focused control tools. A construction contractor may need a diesel-driven system with a water tank, booster pump, hose reel, and mobile frame.
When selecting an ultra high pressure pump system, buyers should provide the required pressure, flow rate, application, hose length, water source, operating environment, and preferred accessories. Fussen can then configure a complete system that includes the pump, hoses, guns, nozzles, water supply equipment, and safety components needed for reliable industrial operation.
Ultra high pressure water jetting should be treated as a specialist industrial process, not as an upgraded version of ordinary pressure washing. At pressures from 1,000 bar upward, the water jet can remove coatings, rust, scale, and concrete—but it can also cause serious injury, damage equipment, or create uncontrolled hazards if the system is incorrectly configured or operated.
For industrial buyers, safety should be considered during system selection, project planning, operator training, and daily operation.
Operators should understand more than how to start and stop the pump. They need training on the specific water jetting task, including nozzle handling, safe working distance, hose movement, emergency shutdown, pressure release, and the risks associated with the material being removed.
Training should cover:
For contractor teams, consistent training is especially important when operators move between shipyards, refineries, construction sites, and industrial facilities.
Personal protective equipment should match the pressure level, water jetting task, and site conditions. Depending on the application, this may include protective clothing, gloves, boots, eye and face protection, hearing protection, and water jetting-specific protective equipment.
The work area should also be controlled. Establishing exclusion zones helps prevent other personnel from entering the line of fire, walking near pressurised hoses, or being exposed to debris, splashback, noise, and slippery surfaces.
A well-planned work zone should consider:
Every component in the high-pressure line must be rated for the system’s maximum working pressure and flow rate. This includes hoses, couplings, guns, lances, nozzles, fittings, and safety restraints.
Before each shift, operators should inspect for:
A component that appears acceptable at low pressure may fail under ultra high pressure. Damaged hoses or fittings should be removed from service rather than repaired informally on site.
Ultra high pressure systems should include properly configured pressure control and protection devices. These may include pressure regulating valves, safety valves, bursting discs, pressure gauges, emergency shutdown controls, and low-water protection systems.
These components help protect the pump and operator if there is a blocked nozzle, sudden pressure increase, water supply interruption, or system malfunction.
The system should never be operated above the rated pressure of the lowest-rated component. For example, a pump may be capable of 2,800 bar, but if the hose, gun, or nozzle is rated below that level, the entire system must be limited to the lower rating.
Before changing a nozzle, disconnecting a hose, servicing a pump, or inspecting internal components, the system must be fully shut down, isolated from its power source, and depressurised.
For electric systems, this means isolating electrical power. For diesel systems, it means stopping the engine and preventing accidental restart. The operator should confirm that pressure has been released from the hose and gun before beginning maintenance.
Lockout and depressurisation procedures are especially important during multi-person work, where one person may be servicing equipment while another person is operating or preparing the system.
Ultra high pressure pumps depend on a stable water supply. Operating without sufficient inlet water can quickly damage seals, plungers, valves, and other internal components.
To reduce this risk, the system should include appropriate filtration, stable inlet flow, water level monitoring, float valves, booster pumps where required, and low-water protection. Operators should also confirm that filters are clean and that the water source can provide sufficient flow before starting the pump.
A properly configured water supply system improves both safety and equipment life.
The safest ultra high pressure system is one designed around the actual job. This includes the correct pressure and flow rate, properly rated hoses and accessories, suitable control tools, stable water supply, trained operators, and planned maintenance.
For Fussen customers, the system specification should be based on the application, working environment, power source, hose length, nozzle type, operating hours, and safety requirements—not only the maximum bar rating.
Ultra high pressure pumps operate under high mechanical load, high water pressure, and continuous exposure to wear. A planned maintenance routine helps maintain stable performance, reduce unexpected downtime, and protect major components such as plungers, seals, valves, hoses, and nozzles.
The goal is not simply to repair equipment after a failure. It is to identify small issues before they become costly shutdowns.
Water filtration is one of the most important maintenance points. Dirt, sand, rust particles, and other contaminants can damage plungers, seals, inlet valves, outlet valves, and nozzle orifices.
Before starting the system, operators should check:
Filters should be cleaned or replaced according to the operating environment and water quality. Sites using tanks, river water, recycled water, or temporary water sources may require more frequent inspection.
Even a high-quality ultra high pressure pump can suffer premature wear if the water supply is unstable or contaminated. The water source should provide sufficient inlet flow for the selected pump model, with a booster pump or tank system used where necessary.
Operators should monitor for signs of water starvation, such as:
A stable water supply helps prevent cavitation, which can damage internal pump components and reduce performance.
Seals, hoses, fittings, and nozzles are wear components. They should be inspected before operation and monitored during long projects.
Look for:
Replacing a worn nozzle early is often less expensive than continuing to operate with reduced cleaning efficiency, unstable pressure, or unnecessary load on the pump.
Stable pressure is a key indicator of pump health. Sudden or repeated pressure fluctuations may indicate:
Operators should investigate unusual pressure changes promptly rather than increasing the pressure setting to compensate.
The crankcase, bearings, crankshaft, and plunger assembly require regular inspection according to the manufacturer’s maintenance schedule.
Typical checks include:
Fussen systems may use ceramic plungers for wear and corrosion resistance or alloy steel plungers for high-strength operating conditions. Regardless of material, plungers should be kept clean and inspected for damage, scoring, or abnormal wear.
Nozzle wear is often overlooked, but it directly affects pressure, flow pattern, and cleaning performance. As a nozzle orifice wears, the jet may become less concentrated, pressure may drop, and the pump may operate less efficiently.
Replace nozzles when operators notice:
Using the correct nozzle size also helps prevent excessive pump load and ensures the system operates within its intended pressure and flow range.
If equipment will be stored or operated in freezing temperatures, water left inside the pump, hoses, fittings, and accessories can freeze and cause serious damage.
For cold-weather storage or transport:
This is particularly important for mobile diesel systems used in outdoor construction, municipal, railway, or infrastructure projects.
For continuous-duty industrial equipment, maintenance should be scheduled based on operating hours, application severity, water quality, and site conditions.
A practical schedule may include:
| Частота | Typical Maintenance Tasks |
|---|---|
| Before each shift | Check filters, water supply, hoses, fittings, nozzles, oil level, and visible leaks |
| During operation | Monitor pressure, flow, vibration, noise, water supply, and temperature |
| Weekly | Inspect seals, couplings, hose condition, nozzle wear, and safety devices |
| Monthly or based on operating hours | Check lubrication, valves, plungers, pressure controls, and electrical or diesel engine components |
| Before long-term storage | Drain water, clean filters, inspect wear parts, protect against freezing, and store safely |
For demanding work such as hydroblasting, shipyard maintenance, refinery shutdowns, and continuous industrial cleaning, the maintenance interval may need to be shorter. A documented maintenance plan helps operators track wear parts, reduce unplanned downtime, and extend the working life of the ultra high pressure pump system.
Choosing a Supplier for an Ultra High Pressure Pump
An ultra high pressure pump is a long-term industrial investment, not a standard commodity purchase. The supplier affects more than the initial equipment price: it influences system reliability, cleaning productivity, operator safety, maintenance cost, spare-parts availability, and the ability to adapt the system as project requirements change.
The best supplier should understand the application as well as the pump specification. A supplier that only asks for a pressure rating may provide a machine, but a supplier that asks about the material being removed, required flow rate, water supply, duty cycle, operating environment, mobility, and safety requirements is more likely to recommend a system that performs reliably in real working conditions.
| Evaluation Area | What Buyers Should Check | Why It Matters |
|---|---|---|
| Pressure and flow range | Available pressure, flow rate, motor or engine power, and whether the supplier can match the required operating point | Pressure alone does not determine performance; the right pressure-flow combination affects removal efficiency and cleaning speed |
| Industrial application experience | Experience in shipyards, refineries, construction, manufacturing, municipal maintenance, or industrial cleaning | Application knowledge helps avoid incorrect configuration and improves project results |
| Pump materials and seal quality | Plunger material, valve quality, seal design, corrosion resistance, and suitability for water quality and temperature | Wear components directly affect pump life, maintenance frequency, and uptime |
| Safety design | Pressure relief devices, bursting discs, safety valves, gauges, emergency shutdown, low-water protection, and correctly rated accessories | Ultra high pressure systems require complete protection for operators and equipment |
| Customisation capability | Ability to configure pressure, flow, power source, frame, tank, filtration, hose length, nozzles, and control system | Many industrial projects need a system built around the site rather than a standard machine |
| Certifications and quality control | ISO quality management, CE compliance, electrical safety, and project-specific compliance requirements | Certifications support procurement approval and help confirm consistent manufacturing standards |
| Spare parts and technical support | Availability of seals, valves, plungers, hoses, nozzles, service documentation, troubleshooting support, and response time | Fast access to support and wear parts reduces costly downtime |
| Complete system supply | Ability to provide the pump together with motor or diesel engine, water tank, filtration, booster pump, hoses, guns, lances, nozzles, and safety devices | A complete system reduces compatibility risks and simplifies installation, commissioning, and after-sales support |
A supplier should be able to explain why a particular pressure and flow rate are suitable for the job. For example, coating removal, tank cleaning, ship hull preparation, hydrodemolition, and pipe cleaning all require different combinations of pressure, flow, nozzle type, hose length, and operating method.
Before requesting a quotation, buyers should prepare basic project information:
The more clearly these details are defined, the more accurately the supplier can configure the system.
The pump is the core of the system, so buyers should ask about plunger materials, seals, valves, lubrication, filtration requirements, and recommended maintenance intervals.
For example, ceramic plungers are often selected for their wear resistance, corrosion resistance, and smooth surface finish, while alloy steel plungers can provide high strength and impact resistance for demanding operating conditions. Seal materials should also match the working environment, particularly where corrosion, high temperature, saltwater exposure, or chemical residues are present.
A reliable supplier should be able to explain which pump materials and seal configuration are appropriate for the project rather than offering one standard solution for every application.
Ultra high pressure water jetting equipment should include safety design from the beginning. Buyers should confirm that the supplier can provide properly rated hoses, guns, fittings, nozzles, pressure relief devices, gauges, emergency shutdown controls, and low-water protection.
The supplier should also be able to recommend suitable dump guns, hose restraints, protective covers, filtration systems, and other accessories based on the selected pressure and flow rate.
Safety should not be treated as an optional add-on. A system is only as safe as its lowest-rated component.
Many projects need more than a pump and motor. A refinery shutdown contractor may need a mobile diesel system with long hoses, pipe-cleaning nozzles, filtration, and safety controls. A shipyard may need an electric system with corrosion-resistant components, hose reels, rotating nozzles, and stable water supply. A construction contractor may require a skid-mounted or trailer-mounted system with a water tank and booster pump.
Choosing a supplier that can provide the complete package reduces the risk of incompatible components and makes commissioning easier.
Фюссен manufactures high-pressure and ultra high pressure water jet systems for industrial cleaning, surface preparation, hydroblasting, concrete removal, and specialist maintenance applications. With pressure capability up to 2800 бар and flow rates up to 1000 л/мин across its wider product range, Fussen can support projects that require more than a standard pressure washer.

For ultra high pressure applications, Fussen offers:
By supplying the pump, power source, water supply equipment, accessories, and safety components as one integrated system, Fussen helps buyers reduce compatibility risks and configure equipment around the actual job site.
For an accurate recommendation, share your application, required pressure and flow rate, power source, water supply, operating environment, expected duty cycle, and preferred accessories. Fussen’s engineering team can then recommend an electric, diesel, or customised ultra high pressure pump system that matches your project requirements.
