The NP&P Strap Pump series is carefully designed and manufactured for maximum resistant against sand and Other impurities providing a long life and trouble free operations. The Floating Impeller design ensures an excellent resistance to wear and tear against sand and other impurities. The Discharge Head and Motor Adapter are made of precision-cast stainless steel ensuring maximum resistance to corrosion, strength and rigid coupling to the motor. The Check Valve is integrated in the head to support the weight of the water column and to protect against water hammer, thus safeguarding impellers and diffusers. The pump can also be installed horizontally. Our 5.5″ Line is also cutting edge, using a Stainless Steel Cast Impeller, Stainless Steel Cast Bowl, Stainless Steel Cast Motor Bracket, & Stainless Steel Cast Discharge Case. Our 5.5″ SS line is perhaps the best strap pump on the market today. The units are fully rebuild-able and have a keyed shaft. Along with our OEM partners we will keep these units in stock for your pumping applications.
