Cat Pumps Plunger Pump 42HS

Each system’s maintenance cycle will be exclusive. If system performance decreases, check immediately. If no wear at 1500 hours, check again at 2000 hours and each 500 hours until wear is observed. Valves typically require changing every other seal change. Duty cycle, temperature, quality of pumped liquid and inlet feed conditions all effect the life of pump wear parts and service cycle.

Remember to service the regulator/unloader at each seal servicing and check all system accessories and connections before resuming operation.

Fill crankcase with special CAT PUMP oil per pump specifications [5PFR-18 oz., 7PFR-25 oz., 15PFR-42oz.]

Check if pump is running without oil in crankcase

Change initial fill after 50 hours running period. Thereafter, change oil every 3 months or 500 hour intervals, whichever comes first.

Check if pump was designed for forward rotation to allow optimum lubrication of the crosshead area.

Check if reverse rotation is acceptable if the crankcase oil level is increased slightly above center dot to assure adequate lubrication.

* If other than CAT PUMPS special multi-viscosity ISO68 oil is used, change cycle should be every 300 hours.
