Advantages 
  • water saving: at suction pressures < 600 mbar, the water can be completely retained in the pump
  • low noise due to optimized hydraulics and separation
  • low calcification risk and easy temperature control possible 
  • easy disassembly due to inverted design and
    O-ring sealing
Possible applications
  • extruder degasification 
  • sterilization of surgical instruments, textiles and beds (steam and gas sterilization)
  • evacuation in central vacuum systems
