Plunger Pumps
Plunger pumps are utilized world-wide in thousands of applications. Cat Pumps’ industrial duty high pressure positive displacement triplex plunger pumps are recognized as the longest-lasting, most reliable plunger pumps in the industry.
Plunger pumps direct flow through the pump manifold by using spring-loaded closed and hydraulically opened inlet and discharge valves. At the beginning of the stroke, the plunger displaces the liquid in the manifold chamber, forcing the discharge valve open. When the plunger reaches the end of the stroke, the discharge valve closes. As the plunger rod begins its backward stroke, the inlet valve opens again to allow more liquid into the manifold chamber, which keeps a smooth forward flow of liquid.
CAT Pumps designs and manufactures plunger pumps for a range of specifications
-
- 0.13 GPM to 240 GPM (0.49 to 908 LPM)
- 100 PSI to 10,000 PSI (6.9 BAR to 689 BAR)
- available in brass, nickel aluminum bronze, 304, 316, and duplex stainless steel
- electric motor, gas/diesel engine, hydraulic, and pneumatic
Piston Pumps
Piston pumps are reliable, efficient, durable and versatile, giving users the best value. Industrial duty high pressure positive displacement triplex piston pumps offer superior suction capability, often not requiring flooded suction or booster pumps.
-
- 3.0 GPM to 60 GPM (11.3 to 227 LPM)
- 100 PSI to 1,500 PSI (6.9 to 103 BAR)
- available with brass and 316 stainless steel manifolds and 304 stainless valve components
Centrifugal Pumps
Centrifugal pumps offer a solution to high-flow, low-pressure pumping needs. Pump housings are constructed from bulge formed 304 stainless steel that is stronger, lighter, more durable, and more cost-effective than conventional cast iron pumps.
Choose from:
-
- manual or automatic float (submersible)
- chemical resistant or high-temperature seals
- flanged or NPT fittings
- single or three phase, ODP or TEFC, 50 or 60 Hz, up to 575 volt, 1750 or 3450 RPM motor options
Multi-Stage Centrifugal pumps designed for long life and trouble-free service in a range of applications including booster, hot water, and water purification.
Stainless Steel Pumps
Successfully operate in some of the harshest environments, and offer corrosion resistance for applications with aggressive liquids.
Flush Pumps
Flush pumps are highly effective in extending seal life when pumping low-lubricity liquids.
Flushed manifold pumps are designed to:
-
- Increase seal life when used with low lubricity fluids such as de-ionized (Di) water
- Extend seal life by cooling seals in applications with elevated pumped liquid temperatures
- Reduce likelihood of cracking or pitting by reducing thermal load on ceramic plungers
Liquid C02 Pumps
CAT Pumps has been designing liquid C02 pumping solutions for over 20 years, with a range of models available in brass or 316 stainless steel.
TEG Pumps
With temperatures up to 240 F, Triethylene glycol (TEG) dehydration is very demanding on the components within the system.
Cat Pumps’ specially-modified pumps use a proprietary seal design to run in the most demanding and heavily-used dehydration systems used to remove water from natural gas.
These TEG pumps are engineered to run continuously in TEG dehydration systems.
High Temperature Pumps
CAT Pumps high temperature and dry run pumps offer field-proven technology for any high-temperature application. These high temperature pumps:
-
- handle liquids up to 200°F/93.3°C
- perform in intermittent run-dry conditions
- offer flow range of 0.5 to 20 GPM/1.9 to 75.7 LPM
- offer pressure range of 100 to 3500 PSI/6.9 to 241.5 BAR
- are available in brass, nickel aluminum bronze, and stainless steel
Nickel Aluminum Bronze Pumps
Nickel aluminum bronze pumps offer superior strength and corrosion-resistance necessary for oilfield and reverse osmosis applications.
Available in flow and pressure ranges from 0.13 – 75 GPM, and 100 – 5,000 PSI.
Direct Drive Pumps
Cat Pumps’ direct-drive pumps, available for electric and engine drives, offer compact and cost-effective pump mounting.
This option allows for easy installation with the pump mounting directly to the motor or engine.
Belt Drive Pumps
Highly dependable belt-driven piston and plunger pumps offer flow flexibility given within pulley ratios, allowing the operator to change the pump flow by simply changing the pulley.
The belt drive isolates the pump from the heat and vibration of the motor or engine. At the same time, the belt isolates shock from an engine or motor on startup, reducing wear on the crankshaft and drive end components.
Gearbox Pumps
Gearbox pumps hold up to the rigorous demands of commercial and industrial pressure washers.
These direct-drive high-pressure pumps can be easily mounted on standard gas or diesel engines up to 24 horsepower. The completely sealed gearbox drive has a 2 to 1 ratio allowing the pump to run at half the speed of the engine.
ATEX Pumps
CAT Pumps offers a complete line of ATEX certified plunger pumps for use in potentially explosive atmospheres, compliant with the ATEX directive for Group 2, Category 2 and Zones 1 and 2 (Group 2 includes Zone G).
CAT Chemical Pumps
CAT Pumps offers a wide selection of elastomers and manifold materials to meet a large variety of applications.
