How the SUPER J vacuum-assisted unit works

The system consists of a J self-priming 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.


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
  • Self-priming centrifugal pump which secures operation in case of a fault with the vacuum pump

Semi-open impeller with solids handling making the units suitable both for drainage and for wellpoint systems

Three kinds of vacuum pump: no contamination of the environment

Rotary vane vacuum pump lubricated with oil recirculation system
