Constructed of die-cast aluminum, 2770 Series pumps feature stainless-steel valves with a recessed inlet valve. The cylinder is hard-coated for wear resistance, and all wetted aluminum parts are treated for corrosion protection. Oilless, nonlube piston and cylinders, combined with an air-intake filter, prevent contamination. Thermally protected, permanent splitcapacitor ac motors provide reliable service, and twin fans efficiently cool the motor and cylinder. TFE piston seals are field replaceable. The pumps are rated to 100 psi and 7.4 cfm.
