Ws+ Series (NEMA) - Self-Priming Centrifugal Pumps

The Ws+ uses a unique design that combines the abilities of most liquid ring pumps with the efficiencies of the W+ centrifugal series. As a result customers can now handle entrained air and lift requirements with lower horsepower, less noise and at lower cost.
