Plunger Design Provides Smoother Liquid Flow!

Product Announcement from Cat Pumps - High Pressure Pumps & Systems

Plunger Design Provides Smoother Liquid Flow!-Image

Superior Design

  • Triplex plunger design provides smoother liquid flow.
  •  V-Packings and Lo-Pressure Seals are completely lubricated and cooled by the liquid being pumped.
  • Low upswept volume maximizes volumetric efficiency.
  • Oil bath crankcase assures optimum lubrication.
  • Close tolerance concentricity of the ceramic plunger offers perfect alignment and maximizes seal life.

Quality Materials

  • Precision stainless steel seat and ceramic ball provides true sphericity and long life.
  • Block-style, stainless steel manifolds for strength and corrosion resistance.
  • Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life.
  • Special UHMV supported V-Packings for high pressure stability and extended life.
  • Die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
  • Chrome-moly crankshaft gives unmatched strength and surface hardness.
  • Oversized crankshaft bearings with greater loading capacity mean longer bearing life.

Easy Maintenance

  • Wet-end is easily serviced without entering crankcase, requiring less time and effort.
  • Preset packings mean no packing adjustment is necessary, reducing maintenance costs.

Model: 1810


This is a triplex [three plunger rods] positive displacement, reciprocating, plunger pump, constructed of 304S Heat Treated stainless steel block-style manifolds, 304S valve assemblies with ceramic balls, ceramic plungers, acetal seals, UHMV V-Packings and NBR o-rings. The pump features a low unswept volume [minimal un-evacuated liquid remains in the pumping chamber] resulting in maximum volumetric efficiency. This pump is designed for hydro blasting, hydrostatic testing and injection.

Dedication to Quality

Field-Proven Quality, Dependability, Long Life

Dedication to quality has been the foundation of Cat Pumps philosophy since first opening our doors in 1968.  From initial design to materials and manufacturing, the central focus will always be providing the highest quality products possible to better serve our customers.

  • 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 UNFLOW 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 manufacturing facility is ISO 9001 certified. We make use of the latest technologies and computer animated machining equipment to ensure each product is of the highest possible quality. We demand closely held tolerances and maintain a rigorous quality assurance program to guarantee a consistent quality product each 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 delivery meets Cat Pumps Quality standards.

These 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 heavy-duty industrial quality is evident in pumps that were installed 20-30 years ago still running today. Today we are still striving to improve our products and work closely with OEM's and specialty markets to incorporate custom features, tailored to fit your application needs.

Custom Systems

Custom Pumping Systems are referred to by many names. They can be referred to as skid-mounted units, power units, pumping systems, base units, stacked units, pre-packaged systems, aggregates, horizontal pump unit, manufactured system, modular units, pre-assembled pump systems, fabricated systems or multiple pump systems.

Regardless of the name you use, Cat Pumps can custom engineer your industrial pumping system to meet your specific application and installation requirements. With experience in hundreds of different applications, our Custom Systems can be configured to meet any application demands.  Each system includes all the required safety and pressure regulation valves to assure optimum performance and safety. We fully test each pumping system and include an owners manual with start-up and maintenance information.

Our custom pumping systems are the quickest way to get up and running with the proper equipment. Please review the information below and let us know how we can assist you with custom system for your next installation.
