P Series vertical immersible pumps are compact, portable and self-priming when immersed within a tank. Simple in design and efficient in performance, this pump has only one moving part; the impeller. This pump is suitable for pumping, agitating, filtering or circulating acid and alkaline solutions, abrasive fluids, electroless plating solutions and other corrosive solutions. The pump has a rigid, solid stainless steel that extends from the motor fan to the impeller. The shaft sleeve of the impeller eliminates contact of solution with any metal parts. The impeller's top vanes perform the function of the seal allowing for no pump bearing, no bushings, no wearing parts, and open clearances within the pump. This produces little or no maintenance required for the pump. The pump is mounted with a extension flange or baseplate that allows for mounting on the tank lip; pump can be mounted directly in the tank or on the outside of the tank if space is limited.  

This design has been providing reliable service for the most difficult applications for more than thirty years. Materials of construction include CPVC (standard), polypropylene, and PVDF.

A new "K" design now prevents impeller unthreading during reverse rotation of a three phase motor .  Available for P-1 through P-2 and "HP" pumps.  Details

The materials are often combined to allow for special application such as electroless nickel plating. In this case, a CPVC pump is modified (‘EN’ version) with a PVDF impeller to gain the addition thermal and corrosion strength of the PVDF material without the additional price increase required for a total PVDF constructed pump.
