MULTIJECTOR® Designs


Multijector vacuum pumps K series multiple stage venturi ejectorMULTIJECTOR® Vacuumpumps Type K are 2-stage ejector pumps with small size and low weight. The Multijector K is energy saving and specially designed for applications in the field of vacuum handling and automation.

  • strong Aluminium design
  • max. -93 kPa Vacuum (up to -97 kPa on request)
  • Suction air streams 70 to 240 Nl/min
  • optional with integrated vacuum switch
  • optional with ON/OFF valve and quick release blow-back valve

Multijector vacuum pumps M and ML series multiple stage venturi ejectorMULTIJECTOR® Vacuumpumps Type M and ML are 3-stage Ejectors with small size and low weight. Because of their high capacity they are the optimum choice as a compact vacuum source with a flow up to 2 m3/min.

  • Pump completely in Aluminium, long lasting design
  • max. -91 kPa Vacuum (max -97 kPa on request)
  • Suction air streams from 200 to 2250 Nl/min
  • Operating pressure: M-Types opt. 5.6 bar, ML-Types opt. 3.4 bar
  • Nitrile rubber-, Viton- or EPDM-sealings
  • optional with Energy control system

MULTIJECTOR® Vacuumpumps Type G and GL are 4-stage Ejectors with the highest efficiency: Their 4th stage gives the pump the "boost" of air-flow in the lower vacuum. So G Types are the right choice for such applications, which require bigger air volumes, e.g. for the quick evacuation of bigger volumes, for more complex handling applications or for vacuum conveying.
And even the "biggest" Multijector has a weight of just 17 kg!
  • max. -91 kPa Vacuum (max. -97 kPa on request)
  • Suction air streams from 900 up to 20500 Nl/min
  • Operating pressure: G-Types opt. 5,6 bar, GL-Types opt. 3,4 bar
  • Nitrile rubber-, Viton- or EPDM-Dichtungen
  • optional with Energy control system

Multijector vacuum pumps MRVA and  MRVAC series multiple venturi ejector in stainless steel, CIP option, multiple stage venturi ejectorMultijector MRVA and MRVAC
Multijector Vacuumpumps in stainless steel

Multijectors MRVA and MRVAC are ideal for applications inside the Chemical-, Pharma- and general Process-Industry, where aggressive substances are present or critical operation conditions are to be taken into account.

  • Pump completely in stainless steel
  • max. -91 kPa Vacuum (max. -97 kPa on request)
  • Suction air streams from 1150 up to 1800 Nl/min
  • Operating pressure: opt. 5,6 bar
  • Viton-, EPDM- or Teflon-coated gaskets
