CAT Pumps – Aqua Components

CAT Belt Drive Pumps

aqua@2025 — Thu, 13 Mar 2025 13:57:46 +0000

Cat Pumps offers a range of belt-driven pumps from 0.13 GPM up to 240 GPM. Belt-drive is a very popular option because of the 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. Belt-drive pumps give the flexibility of changing pump flow by a simple pulley change.

Belt-driven pumps are available in brass, nickel aluminum bronze and stainless steel with a wide range of flow and pressures: 0.13 – 240 GPM, and 100 – 10,000 PSI. Complete drive packages (pulleys, hubs, keys and belts) are available for all of our pumps.

CAT Belt Drive Pumps Data Sheet

CAT Direct Drive Pumps

aqua@2025 — Thu, 13 Mar 2025 13:57:44 +0000

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. The hollow shaft pumps fit 56C or 184TC face motors and will bolt directly to the unit. The bell housing mount utilizes a flex coupler between the pump and motor shafts, and the bell housing mounts the pump to the motor. Bell housing direct-drive pumps are commonly used up to 15 HP.

For engine direct-drive pumps there are two options available: hollow shaft pumps and gearbox pumps. Both options bolt directly to the engine, but the gearbox version allows the pump to run at half the speed of the engine.

CAT High Temperature Pumps

aqua@2025 — Thu, 13 Mar 2025 13:57:43 +0000

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 high temperature pumps can handle liquids up to 200°F/93.3°C and perform in intermittent run-dry conditions. Flow range of 0.5 to 20 gpm/1.9 to 75.7 lpm and a pressure range of 100 to 3500 psi/6.9 to 241.5 bar. Available in brass, nickel aluminum bronze and stainless steel to cover a wide variety of applications.

Models

.3000 Series

190° F / 88° C, High-Temperature

The “.3000” series has the high pressure seal/V-Packing modified to handle temperatures up to 190° F / 88° C. These seals are a two part construction of PTFE blend with a stainless steel backing for added strength and support at high temperatures. Ordering this configuration requires adding “.3000” to the base model on plunger pumps, or “3” at end of model number for 2SF series pumps.

240°F / 115°C, High-Temperature and Intermittent Run-Dry Plunger Pumps

The “.44101” series plunger pump modifies the high pressure seal/V-Packing and low pressure seal to special blend PTFE high temperature material. FPM O-rings capable of the increased temperature rating are installed throughout the pump. Proprietary modifications are made to the drive-end to withstand the added temperature and provide proper heat displacement. Ordering this configuration requires adding “.44101” to the base model.

CAT Gearbox Pumps

aqua@2025 — Thu, 13 Mar 2025 12:47:44 +0000

Cat Pumps gearbox pumps are direct-drive high-pressure pumps that can be easily mounted on standard gas or diesel 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. This configuration provides a compact assembly without running the pump at high engine RPM. The gearbox is completely sealed, offering protection against rain, dust, and humidity. 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 TEG Pumps

aqua@2025 — Thu, 13 Mar 2025 12:47:40 +0000

Triethylene glycol (TEG) dehydration is the most common method of removing water from natural gas. The TEG can be up to 240 F, which is very demanding on the components within the system. Cat Pumps’ specially-modified pumps using a proprietary seal design are engineered to run in the most demanding and heavily-used dehydration systems.

Cat Pumps has spent years working with engineers and maintenance professionals in the natural gas industry to develop the best solution for the TEG dehydration application. After extensive research & development and field testing, Cat Pumps launched this industry-changing product the first quarter of 2011. The product line is expanding to meet the variety of demands for TEG Dehydration. Pumps are readily available for 0.5 – 25 GPM and can be fitted with brass or 316 stainless steel manifolds. A full-line of product accessories are available and pumps can be built into a custom-engineered system.
