We continue to develop the most advanced coating technologies that cover a wide range of applications. We stock four premier plungers that include: tungsten carbide, ceramic, Kerramic and Black Gold. Our tungsten carbide plunger lasts twice as long as the nickel alloy that exhausts the marketplace.
Kerr Pumps manufacturers a wide variety of high quality valves and seats. We offer plenty of configurations and materials to choose from such as our more popular salt bath nitrided 17-4 stainless steel. We also keep in stock a full line of Well Service inserted valves and o-ringed seats.
Our engineers have developed piston assemblies with precision molded replaceable piston cups, molded in fabric reinforced nitrile rubber. Coupled with a 300 series stainless steel piston body, this assembly ensures optimum corrosion and abrasion resistance, regardless of liner material.
We manufacture replacement stuffing boxes in a variety of styles, sizes and materials for a broad range of packing arrangements and elastomers. The necessary precision in each box enables a perfect interface for maximum packing life even in the most demanding temperature and pressure conditions.
The entire Kerr Pumps product line utilizes high strength cast ductile iron, maintaining stable housings for precision fit wrist pin bushings and crankshaft inserts. Each connecting rod is made from U.S. foundries and is machined on one of our precision CNC horizontal machining centers.
All of our pony rod glands are machined in-house on one of our many CNC lathes. The level of precision and finish in each gland gives an incredible repeatability from part to part. This consistency extends the life of each seal and pony rod which keeps you pumping longer in the field.
We believe that making incredible pumps is just part of the game. Our main focus is taking care of our customers. That is why we stock a full line of pump replacement parts. We do our absolute best in meeting customer demands and continue to strive to be the most responsive pump company.
