HPW Hydraulic Power Washer

DYNASET HPW Hydraulic Power Washer converts the hydraulic power of a mobile machine, vehicle or vessel into high-pressure water for pressure washing. 

The HPW Hydraulic Power Washer converts the hydraulic power of a mobile machine, vehicle, or vessel into high-pressure water for efficient, high-performance pressure washing. Equipped with a wheeled, easy-to-maneuver frame and holsters for hose storage, it’s simple to transport and operate. Its self-priming capability allows it to draw water from sources up to 3 meters below, making setup easy and enabling fast operation even in challenging locations. With low water consumption and cost-effective operation, this washer provides the world’s best power-to-size ratio, making it ideal for a range of demanding washing applications. Just connect the hydraulic hoses, attach the water supply, and you’re ready to power wash!

How Does the Hydraulic Power Washer Work?

The hydraulic high pressure water pump of the washer utilizes a machine’s, vehicle’s or vessel’s hydraulic system as power source 

  1. The hydraulic high-pressure water pump, integrated into the washer’s carry handle, utilizes a machine’s, vehicle’s, or vessel’s hydraulic system as its power source. 
  2. Hydraulic oil flow is directed to the hydraulic high-pressure water pump through the pressure line. 
  3. The hydraulic high-pressure water pump converts the hydraulic oil flow and pressure into high-pressure water. Once connected to water supply, the pump self-primes, and power washing can begin immediately. 
  4. The hydraulic oil is then returned to the carrier machine’s hydraulic oil tank through the return line.
