20-90% more efficient than other liquid rings due to improved fluid flow through pump.Performance optimized by matching impeller size to duty.Low noise level: Due to its hydraulic design the noise level of the Ws+ is significantly lower than traditional liquid ring pumps.3-A (optional) and EHEDG approved.Interchangeable with W+ parts. Inventory is reduced by sharing common parts.Less prone to damage. Small objects can pass through pump with minimal damage.
The pump is approved by the EHEDG (European Hygienic Equipment & Design Group) as a hygienic pump and is also approved according to the American 3-A standard (optional). Consequently the pump can be used as a CIP as well as a first class hygienic product pump.

The Ws+ series consist of 3 pump sizes.

Ws+ 20/15Ws+ 30/30Ws+ 44/50
At 50 Hz the Ws+ operates at a maximum pressure of 6.5 bar (94 psi) and a flow capacity of 90 m3/hour (396 GPM), while the values for a pump with a 60 Hz motor is 9.5 bar (138 psi) and 110 m3/hour (484 GPM).
