Compact, two-stage, external gear pumps designed for use at elevated pressures. 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. 1/2'' shafts use 404 woodruff key. 5/8'' shafts use 3/16'' x 1'' straight key. 4,000 RPM max. Maximum pressure 3,000 PSI.
