Plunger Pumps use spring-loaded closed and hydraulically opened inlet and discharge valves to direct flow through the pump manifold, keeping a smooth forward flow of liquid.

With proven dependability, Cat Pumps' plunger pumps are used world-wide in thousands of applications.

The design of the piston pump allows the fluid to move continually in one, smooth forward
direction. This design allows greater suction capabilities and reduces the risk of cavitation
provided the pump is properly primed.

Cat Pumps' piston pumps are reliable, efficient, durable and versatile, giving users the best value for the dollar.

Cat Pump's Centrifugal pumps have both inlet and discharge valves are spring-loaded closed and hydraulically opened, and they have a flow-through ceramic plunger design,

This offers solutions to high-flow, low-pressure pumping needs and complement the triplex pump line.

Flush pumps are used for low lubricity liquids (Deionized water) and liquids with elevated temperatures.

Cat Pumps' flushed manifold pumps are designed with an inlet and outlet flushing port to circulate liquid between the high pressure and low-pressure seals to extend seal life and reduce pump maintenance.

Cat Pumps' liquid CO2 series of pumps feature modifications to accommodate the unique properties of liquid CO2. Specialty seals are used to handle low lubricity and low temperature. Pump manifolds are modified to allow higher inlet pressures and discharge pressures. Drive-end and manifold material combinations are available to cover a wide flow range of flow.

Triethylene glycol (TEG) dehydration is the most common method of removing water from natural gas. Emission compliance and reliability of the glycol system equipment, especially the glycol pump, is essential.

Cat Pumps’ specially-modified electric/engine-driven TEG pumps use a proprietary seal design and have been engineered and field-proven to run in the most demanding and heavily-used dehydration systems.

High-temperature liquids place extraordinary demands on system components, especially the pump. Premature pump failure can lead to production downtime, added maintenance costs, damaged final product, and increased personnel hazards.

Avoid potential problems by counting on Cat Pumps' field-proven technology for your high-temperature applications.

Cat Pumps’ direct-drive pumps offer a compact and cost-effective pump mounting, and are available for electric and engine drives. This option allows for easy installation with the pump mounting directly to the motor or engine.

For electric motor direct-drive pumps there are two options available: hollow shaft pumps and bell housing. For engine direct-drive pumps there are two options available: hollow shaft pumps and gearbox pumps.

Cat Pumps gearbox pumps are direct-drive high-pressure pumps easily mounted on engines up to 24 horsepower. The gearbox drive has a 2 to 1 ratio allowing the pump to run at half the speed of the engine. 

Cat Pumps gearbox pumps are #1 in commercial-duty pressure washers due to superior product life and ability to perform well in continuous duty use.

Cat Pumps offers a full range of pumps that meet the ATEX 2 directive for pumps used in an
explosive atmosphere.

Cat Pumps has been certified as ATEX 2 compliant, which also covers the ATEX 3 requirements. Pump compliance with the ATEX directives is common in industries such as petrochemical, chemical, oil & gas, and bio-fuels.

Cat Pumps offers a wide selection of elastomers and manifold materials to meet a large variety of chemical application needs.

Cat Pumps products work best with fluids with a pH level between 5 and 9 and a viscosity less than 500 cP (centipoises).

Cat Pumps offers a range of belt-driven pumps from 0.13 GPM up to 240 GPM. Belt-drive benefits from flow flexibility given within pulley ratios.

Using a belt-drive isolates the pump from the heat and vibration of the motor or engine driving the pump. The belt also isolates shock from an engine or motor on start up, which can put excess wear on the crankshaft and drive end components. 

Designed for long-life and trouble free service, the 8K series is a superior line of multistage centrifugal pumps.

Originally engineered for booster, water purification, and hot water applications, many other industries have adopted this product due to its reliable performance.

Cat Pumps offers a complete line of stainless steel pumps to meet the demands of many industrial applications. The stainless steel pumps offer superior corrosion resistance, strength and long life in the applications where aggressive liquids are being pumped. 

Cat Pumps offers a complete line of nickel aluminum bronze pumps to meet industry demands. These pumps are frequently found in oilfield and reverse osmosis applications throughout the world.

The superior strength and corrosion-resistance of nickel aluminum bronze, combined with Cat Pumps’ dependability, makes them an industry-leading choice.
