Dewatering Pump with vacuum pump, Max. flow 340 m3/hour & Max. head 27 m with Diesel Engine

The system consists of a self-priming centrifugal pump and a Simplex separator which enables air to be separated from the liquid and be sucked by a vacuum pump – making automatic priming possible. Even with suction heights of several meters the machine
rapidly evacuates the air from the suction pipe and starts to pump.
– The WEL ECO is capable of drawing significant quantities of air and maintaining a wellpoint system under vacuum, or draining an excavation, thanks to the semi-open impeller which also makes it suitable for pumping liquids with solids in suspension.

– Rapid “dry” priming Up to a height of 8.5 m (27.5 ft)
– High resistance To abrasive liquids and turbid sandy waters
– Semi-open impeller Solids handling up to 76 mm (3″)
– Rotary vane vacuum pump Lubricated with oil recovery system and coalescing
filters: no contamination of the environment
– Wear plates Cast iron (G11 rubber lined) or stainless steel wear plates, that are easily replaceable
