PJ4-4000 Powerful, economical and quiet

The PJ high pressure pump works on the pressure booster principle, with the pressure booster (intensifier) being powered by an electrically-driven hydraulic pump. The intensifier converts oil pressure into water pressure controllable from 300 to 4,000 bar.

A pressure compensated hydraulic axial piston pump is driven by a 30kW electric motor, with a maximum oil pressure of 200 bar. The hydraulic pump has an electronic pressure control and a safety valve that nullifies system pressure when the pump switches off.

  • Excellent cutting quality due to minimal pressure fluctuations through the optimization of stroke volume, a high pressure accumulator and electronic switching by the pressure booster
  • Design and working height provides easy access to all important components
  • User friendly operation via touch panel
  • Very low noise level: <72 DB


To minimize pressure pulses in the system caused by intensifier switching and the opening and shut-off of the cutting head, the system embodies an integrated 2.5 liter accumulator. The accumulator has a proven track record in ensuring considerable reduction in wear of the high pressure tubing and fittings.
