ENpump For Electroless Nickel Plating

Palm International nickel is an especially difficult service for filtration pumps. Not only is the plating solution hot, but tends to plate on any material exposed to it, especially abraded surfaces such as mechanical seal faces. Also the nitric acid used for cleaning is highly corrosive, and will attack most pump materials.

Palm supplies the ENpump especially for this service. They are available from stock with flow rates from 5 to 130 gpm, and with discharge heads from 10 to 88 feet. When the impeller of the pump is installed at a level below that of the solution, the pumps are self priming, whether they are placed inside or outside of the tank.

ENpumps utilize a simple vertical, cantilever, sealless design for minimum maintenance. All of their wetted parts are fabricated from plastic for maximum chemical resistance. The housing and volute are made of CPVC for a maximum operating temperature of 200 F. On pumps larger than 1/4 HP, the impeller is constructed of PVDF (Kynar) for added rigidity. The drive shaft is a single piece of rigid stainless steel, totally covered with either CPVC or PVDF. All of the seals are made of Viton® .

The impeller is the only moving part in an ENpump. It has no seals, bearings or bushings to wear, and thus requires little or no maintenance. The pumps are equipped with totally enclosed fan cooled motors, with easily replaced, oversized bearings. The motor housings are coated with epoxy for chemical resistance.
