Cat Pumps Plunger pump 4SF30GS1

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.
