Reduce your noise level and benefit from the amazing development in self-priming. The self-priming Ws+ is designed to handle Clean In Place (CIP) return and other fluids with entrained air and foam. The unique design reduces the energy consumption and noise of traditional liquid ring pumps by using a high efficiency impeller that can be trimmed to match a specific duty. The Ws+ employs a built in eccentric air screw to form the liquid ring required for its self-priming capability.

• 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+ 20/15
• Ws+ 30/30
• Ws+ 44/50

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