Cat PumpsUpdated 2 days ago
This page outlines confirmed compatibility between Cat Pumps pumps and the replacement models we carry. Matches are determined based on shaft size and type, mounting pattern, rotation, and connection points. The tables below are organized by shaft size and compare original pump specifications with recommended replacements, including psi, US gpm, and rpm. Use your browser’s search function (Ctrl/Cmd + F) to quickly find your model number.
Notes:
- Please ensure shaft size and rpms of the pump match those of your drive.
- A higher hp pump can be driven using a lower hp motor/engine to achieve the required psi.
- A higher rpm pump can be driven using a lower rpm setup to achieve the required flow rate.
- If using a solid shaft pump with a belt & pulley, or a direct coupling, please ensure proper mounting supports.
- Please check the temperature rating if you are running hot water through your pump.
