Self-priming centrifugal pump for entrained air handling
Effortlessly manage entrained air and foam in fluid processing with high efficiency, reducing energy consumption and noise, while maintaining smooth operations across demanding production lines.

Handles Aerated Liquids and Self-Priming Processes
The APV Ws+ Series Self-Priming Centrifugal Pump is engineered to excel in handling aerated liquids, offering energy-efficient operation with reduced noise levels. Utilizing a unique liquid ring formation through its eccentric air screw and fluid recirculation loop, this pump ensures efficient vacuum generation and self-priming performance. Suitable for a wide range of applications, the Ws+ is perfect for food and beverage processors, dairy producers, and chemical facilities, processing products like whey, creams, syrups, and essential oils.
With a throughput capacity of up to 484 GPM and a maximum discharge pressure of 138 psi at 60 Hz, it ensures consistent fluid handling across demanding industrial operations. The Ws+ Series integrates seamlessly into existing lines, featuring interoperability with W+ parts to lower inventory requirements. Constructed from high-grade SS 316L for durability and corrosion resistance, it fulfills stringent hygiene standards, being EHEDG and 3-A certified. Incorporating a built-in Clean-In-Place (CIP) system, it delivers ease of maintenance, enhancing production efficiency while lowering running costs. For added versatility, this pump can be customized to meet specific duty requirements with adjustable impeller sizes, backed by dedicated engineering support.
