Pump Ready For HVAC and Medical

Series 2770 WOB-L piston pumps target medical, dental, HVAC, and other OEM applications.

Constructed of light yet rugged die-cast aluminum, the 2770 Series use stainless-steel valves with a patented 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, and an air-intake filter prevent airflow contamination. Thermally protected ac motors use a permanent split capacitor for ultrareliability. Twin fans efficiently cool the motor and cylinder. Piston seals are TFE. Series 2770 pumps provide up to 100 psi (6.9 bar) of pressure. Maximum flow is rated at 7.4 cfm (209.5 lpm).
