2022 SPX Flow WS+ 30/30 175 Self Priming Centrifugal Pump

The self-priming Ws+ is designed to handle CIP (Clean In Place) 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.
