Diagnosis and Preventive Maintenance Pump Service Extends the Life of Your Cat Pump

Cat Pumps offers a variety of resources to assist with servicing our products. The links shown above get you to important information about preventive maintenance, how to service products (videos) troubleshooting tips, and frequently asked questions. From the “Service” pull-down menu, Service Manuals and Data Sheets can be accessed.

Service Manuals are designed to offer useful information when periodic maintenance is necessary. These are "must read and retain" documents that help you obtain optimum performance from your Cat Pumps products. Each Service Manual includes step-by-step procedures for the disassembly and re-assembly of the pump with additional information about the following:

  • Tools used for manifold removal and seal and valve servicing
  • Preventive maintenance
  • Inlet condition check-list
  • Typical reservoir tank diagram

Data Sheets provide details on each individual pump and include specifications, features, horsepower selection chart, parts list, exploded view, dimensional drawing and cutaway view.

Technical Bulletins include detailed descriptions of important product changes and improvements.

The best safeguard against unplanned downtime or system failure is good preventive maintenance practices and proper system diagnosis. Visit the Preventive Maintenance section to learn more about establishing a maintenance schedule and proper pump diagnosis.
