CAT 3CP 1140
Code: 593

Product detailed description
CAT 3CP1140: performance and connections
The CAT 3CP1140 provides a rated flow of 13.6 L/min at 1725 rpm, with a maximum pressure of 152 bar. Its construction includes a brass manifold, stainless-steel valve assemblies, ceramic plungers and standard NBR seals.
The inlet ports are 1/2 inch NPT female and the discharge ports are 3/8 inch NPT female. Check the existing fittings and drive arrangement before selecting a replacement.
Choose the drive for your installation
Drive options include a belt, clutch, or flexible coupling with a bell housing. Match the drive to the required pump speed and installation dimensions. A motor running at a different speed will not deliver the same rated flow.

CAT Pumps: triplex pumps for demanding applications
CAT Pumps develops high-pressure positive displacement pumps and pumping systems for professional and industrial use. The brand is associated with triplex piston and plunger pump technology, serviceable construction and a broad choice of configurations for different liquids and operating conditions.
Where CAT Pumps are used
Applications extend well beyond vehicle washing. The manufacturer supplies pumping solutions for industrial cleaning, reverse osmosis, food and beverage processing, misting and manufacturing. Specialised models also serve mobile equipment and oil and gas installations.
- Pressure washing and self-service or automatic car wash systems.
- Water treatment, reverse osmosis and controlled liquid delivery.
- Misting, cooling and humidity control.
- Industrial washdown and equipment cleaning.
Materials, installation and servicing
Different pump families use different wetted materials and seals. Select the configuration for the liquid, temperature, pressure and required flow rather than assuming that every CAT pump is suitable for the same service. Drive speed, shaft dimensions and inlet conditions must also match the installation.
Browse our CAT high-pressure pumps to compare models. For maintenance, use the pump model and parts drawing to identify the correct seal, valve or piston components.
