Diesel unit with 5-speed automatic transmission
Fuel economy, efficiency, and versatility have reached a new level
Equipped with an intelligent 5-speed automatic transmission, the new HDP 470 and HDP 500 diesel units automatically adjust pressure and water flow to the specific application. This ensures you always get exactly the power you need for the job at hand—and benefit from unbeatable fuel efficiency.
Fuel economy, efficiency, and versatility have reached a new level
The new diesel generators with 5-speed automatic transmission
Increasing demands require more than standard solutions. Rely on technology that can do more: thanks to its automatic 5-speed transmission, the latest generations of diesel units in the HDP 470 and HDP 500 series flexibly adapt their power to virtually any waterjet application—from tank and pipe cleaning to use with hand-held high-pressure spray guns. This takes efficiency and versatility to a new level and saves up to 54 l/h of fuel, depending on the application.
In everyday use, conditions are constantly changing: surfaces vary, requirements differ, and tools are adapted. This is exactly where the intelligent diesel power units, equipped with robust industrial engines, demonstrate their strengths. They always operate within the optimal range and automatically adjust pressure and water flow without the need for reconfiguration and without wasting time.

Up to any challenge
The flow rate can be precisely adjusted to suit the application, to meet virtually all performance requirements.
Reduced emissions
Optimized power adjustment reduces CO2 emissions and noise
Minimized fuel consumption
Up to 54 l/h in fuel savings, since only as much power is generated as is actually needed
Stable performance
Automatic transmission selects the correct gear depending on the water tool
Reduced wear
Lower speed and operation in the partial-load range reduce wear on the pump and engine
Maximum energy efficiency
Optimized cooling, as there is no water loss
Ausstattung
- Torsion-resistant frame with vibration-damping metal feet
- Thermally insulated spiral silencer for noise reduction of 32 dB(A), with exhaust pipe and rain cap, particulate filter, or AdBlue
- User-friendly ES 4 control system with digital display and monitoring function for the diesel engine and high-pressure pump
- Pneumatic system with a compressor flanged to the diesel engine, air tank, and pressure relief valve
- Pneumatic pressure-regulating or bypass valve, overflow line, and safety device with rupture disc
- Suction-side installation with a pressure-boosting pump and stainless steel water filter
5-speed automatic transmission
Enables flexible power adjustment to different water tools and applications.
ES-4 control
Clear user interface with intuitive operation. Allows for the setup of multiple user accounts and access rights.
5 gears for a wide range of applications
4. / 5. Gear
Full power e.g., for cleaning tanks, vessels, and containers
2. / 3. Gear
Low pump capacity, e.g., for cleaning pipes, lines, and heat exchangers
1st Gear
Low pump output, e.g., for working with high-pressure lances to clean surfaces, for concrete restoration, or for removing coatings and rust.
For gun operation, the high-pressure pump runs at 1/6 of the engine speed, saving up to 54 l/h of fuel.
For gun operation, the high-pressure pump runs at 1/6 of the engine speed, saving up to 54 l/h of fuel.
Performance data
Fuel savings with gearbox when working with a gun: 54 l/h, CO2 savings 140 kg/h
