The system consists of a Z centrifugal pump with semi-open impeller and a Simplex separator where air can separate from the liquid and be sucked by a vacuum pump.

The vacuum pump allows the unit to be primed automatically and capable of drawing significant quantities of air, allowing the priming of a wellpoint system and maintaining it under vacuum, or draining an excavation thoroughly under “snore” conditions.


  • Silenced canopy: from 58 to 63 dB(A) - sound pressure level (LPA) at 10 m
  •  Tank of 250 liters / 66 USG: autonomy of 8 days
  •  Inlet / outlet ports at only 0.5 m / 1.6 ft from ground level
  •  Upward opening canopies: for full access to the pump and the engine

Simplex separator

New high capacity air/water separator - nominal capacity: 120 m3/h / 70.6 cfm

  • Fully mechanical patented system that allows fast priming and is also suitable for wellpoint system
  • Automatic condensate recovery
  • Manual valve to restore atmospheric pressure and the emptying of suction line
  • Suitable for operation in any condition (suction lift or flooded suction installation)
  • Automatic “dry” priming (without first having to fill the pump casing with liquid)
  • High air capacity
  • High efficiency pump: 79%  (6-250 model)
  • High resistance to abrasive liquids: turbid, muddy, sandy waters
Semi-open impeller with solids handling making the units suitable both for drainage and for wellpoint systems
