How Does the Hydraulic High Pressure Water Pump Works?

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

  1. Hydraulic oil flow is led to the hydraulic high pressure water pump through the pressure line
  2. The hydraulic high pressure water pump converts the hydraulic oil flow and pressure into high pressure water
  3. The hydraulic oil is led back to carrier machine’s hydraulic oil tank through the return line
