Seal & Valve Kits
SERVICE INTERVALS
Typically, plunger pumps require only a very basic standard maintenance procedure of regular oil changes and seal and valve replacement.
Seal and valve life are extremely dependent upon the type of pumped liquid, temperature, inlet conditions, system protective devices, filtration,
duty-cycle and maintenance-cycle. Most system failures are not due to the pump, but fail because of other system components.
The Preventative Maintenance Check-List (on page 22) provides a summary of the various system maintenance concerns for all high-pressure systems.
The seals on our pumps, operating under normal conditions, will perform for a minimum of 1500 hours, with most lasting much longer.
The valves typically perform for 3000 hours, with many lasting much longer. Cat Pumps always recommends replacing these items as a kit
since components usually wear at about the same rate.
