The pump unit is installed on a laquered steel frame with motor splints, belt pulleys, belts, protective grating and is equipped with the following components:

  • Electric engine: 30 kW 50Hz 400 V ATEX Ex-D IIB T4
  • Suction hoses and return hoses
  • Low-pressure safety valve at suction hose (20 bar set as default)
  • Low-pressure safety valve at return hose ( 20 bar set as default)
  • Double pulsation damper (compensator)
  • High-pressure safety valve (350 set as default)
  • Pressure switch (set 330 bar)
  • Check valve in the pressure line
  • Strainer (at the cold end piece of the pump)
  • Pressure gauge with pressure gauge shut-off valve (with handwheel)
  • HP cryogenic pneumatic valve for pump venting (controlling in manual mode possible)
  • PT100 temperature sensor (Ex-ia IIC) for leak-detection – cavitation protection – cooling control
  • Cryogenic pneumatic valve NC DN25 - DN32, proximity sensors only show closed position
  • Solenoid valves to control the pneumatic valves
