This compact, two-stage, external gear pump is designed for use at elevated pressures and is ideal for press-type applications requiring fast approach/retract speeds and slower peak actuator work speeds due to horsepower limitations or safety constraints. Rotation is clockwise viewed from the Shaft end. The 1/2" shafts use 404 woodruff key and the 5/8" Shafts use 3/16 key. 3600 RPM max. Maximum pressure is 3,045 PSI.
