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

HPW-SUB Hydraulic High Pressure Water Pump

Converts the hydraulic power of a vessel or machine into high-pressure water for subsea applications. HPW-SUB models are similar to the standard HPW pumps, but their materials have been specifically selected to withstand seawater and operate underwater, from a few meters up to 6km. The center body, heads and plugs are made of stainless steel. Bolts are made of stainless steel or with a special coating. The pumps’ internal components are engineered to resist saltwater as well.

Available in a wide model range with pressure capacities 90-1600 bar (1305-23206 psi) and flow rates 15-150 l/min (4-40 gpm). HPW-SUB pump models offer versatile options to meet the unique and demanding requirements of subsea operations. With minimal water consumption, it is a time-saving and cost-effective solution, offering the world’s best power-to-size ratio for efficient and powerful performance in a compact form.
