Preventive Maintenance

Preventive Maintenance

The best safeguard against unplanned shut-down or system failure is a good preventive maintenance plan. Every installation differs, so a unique maintenance schedule may be required. Below you will find more information about adopting a proper maintenance schedule as well as how to diagnose pump issues.
Cat Pumps triplex pump design offers easy maintenance without the use of special tools, making a routine maintenance achievable without difficulty. Please consult the pump Data Sheet, Service Manual or and Diagnosis Chart to verify service procedures. 

Custom Maintenance Schedule

The table above shows the recommended preventive maintenance schedule, however it is only to be used as a guide. The service life of pumps and wear parts vary by application based on duty-cycle, pumped liquid, temperature, inlet conditions, location of installation and system accessories. It is important to monitor the system carefully. At the first sign of low pressure, make a thorough system examination. Low pressure may be caused by system components other than the pump, such as:

  • Clogged filter
  • Leaks from fittings or connections
  • Cracked or kinked hoses
  • Worn o-rings in safety regulators, check valves or relief valves
  • Loose or worn belts
  • Worn nozzles

If no problems are found with the system components, shut the system down and inspect the pump. Check for contamination in valves. Change seals and record hours for your preventive maintenance schedule. Typically valves should be replaced at every other seal replacement.
