Cat, AR, Giant, General and Comet industrial triplex plunger and axial high pressure pumps use SAE30 Non-detergent Mineral Pump oil. This is specially formulated oil for use in high pressure plunger pumps.
Establishing a regular crankcase oil change schedule is one of the most important steps in preventive maintenance and to assure long pump life. Change initial fill after 50 hrs. of operation. Thereafter change every 3 months or at 500 hr. intervals (depending on usage). Failure to follow these requirements could void the pump warranty. PLEASE RECYCLE: Return USED oil to collection center.
