The 83014679 pump belongs to the Open Circuit Piston Pumps series and is manufactured by Danfoss. It delivers 130 cc per revolution so it can move a large volume of oil per cycle in mobile or industrial hydraulic automation. The pressure-compensated and load-sensing control adjusts flow automatically as demand changes, maintaining stable system performance. A continuous rated pressure of 310 bar supports high-pressure circuits without decreasing service life. The unit operates with counter-clockwise rotation, matching drive arrangements that turn in that direction. A 14-tooth 12/24 pitch input shaft mates with standard splined couplings for secure torque transfer. The SAE-C 4-bolt front flange provides a rigid mounting interface on diesel engines or electric motors. Oil enters through a 2.5 in 4-bolt split flange inlet, reducing inlet restriction at high flow, and a single Viton shaft seal contains fluid while tolerating elevated temperature and chemical exposure.
For additional installation details, there is no auxiliary flange, keeping the housing compact. An adjustable maximum flow limiter lets technicians cap displacement to the required level, preventing excess power draw. The load-sensing setting is 28 bar, signaling the control valve when differential pressure rises above this threshold, while the pressure-compensation setting is 140 bar, causing the pump to reduce swashplate angle as outlet pressure approaches this level. Discharge oil exits through a 1.25 in 4-bolt split flange outlet, sized for the rated flow and pressure. All housing ports use SAE O-ring connections to minimize leakage paths. Ports are arranged axially so hoses run straight forward from the pump body, and a 0.5 in threaded port is included for case drain or instrumentation.
