CAT Pumps dedication to quality:
"Design

A superior product always begins with a superior design.  From the very beginning, our first triplex reciprocating piston pumps introduced two revolutionary design changes to the high pressure pump industry, our patented sleeved-piston rod and our UNIFLOW design concept. The sleeved piston rods permit servicing from the wet-end of the piston pumps, drastically slashing service time, eliminating expensive replacement parts and reducing overall maintenance costs. The UNIFLOW design of the piston pumps delivers a continuous, smooth forward liquid flow through the pump and offers strong suction capabilities.

To increase over-all life of our pumps, we have spent significant time and resources researching each individual component.  Our proprietary spring reinforced, special lipped seal design offers 3-4 times the life than other seals available in the market place, while eliminating the need for packing adjustment. Components such as our concentric solid ceramics plungers, high strength connecting rods and oversized bearings are designed to withstand the most punishing applications, repeated cycles and continuous-duty operation. 
 

Materials

Even a flawless design can prove inferior without the use of quality materials. Over the years our product line has expanded to include materials such as:

  • Brass
  • 3150 Chrome-moly
  • Zamak
  • Nickel Aluminum Bronze
  • Duplex Alloy
  • High Strength TNM Alloy
  • W770 Alloy

The use of all of these different materials ensure that we have a product available to provide the highest level of resistance to corrosion and wear, even in the most  harsh environment.

We are also the only triplex, positive displacement pump manufacturer to offer concentric, solid ceramic plungers. Our concentric high density, polished surface have proven to withstand harsh pumping conditions as well as greatly enhance seal life. Our seals are made of a proprietary special blend material that provides unsurpassed quality in the marketplace.  We also offer other special blend seal materials to meet any application need.
 

Manufacturing

Cat Pumps manufactures its products in an ISO 9001 certified facility, where repeatable processes result in predictable and remarkable product performance. Making use of the latest technologies and computer numerical controlled (CNC) machining equipment, our products meet the highest quality standards.  We demand closely held tolerances and maintain a rigorous quality assurance program to guarantee a consistent quality product every time.

Each individual pump is factory flow and pressure tested as a final step in our quality process. We frequently take pumps from inventory and life test to ensure that each product meets Cat Pumps quality standards.  The result: quality and performance you can count on every time.

Quality components and processes have provided optimum pump life of Cat Pumps’ products since the very beginning, earning us the reputation as “the pumps with nine lives.” Our industry leading quality is evident in pumps that were installed 20-30 years ago still running today.  We engage in continuous improvement activities and work closely with OEM's and customers in specialty markets to incorporate custom features tailored to fit specific application needs."
