The 83013247 pump is part of the Open Circuit Piston Pumps series from Danfoss and is intended to supply regulated hydraulic flow in automated machinery. It displaces 74 cc per revolution to support moderate flow rates, and it sustains a continuous pressure of 310 bar for high-force actuators. A combined pressure-compensated and load-sensing control adjusts output to match demand and avoid energy loss. The pressure compensator is preset to 210 bar so the swashplate reduces stroke as system pressure nears this limit, while the load-sense circuit maintains a 20 bar margin across control valves to keep motion stable. Counter-clockwise rotation must be matched to the drive shaft direction, and a 14-tooth 12/24-pitch spline transfers torque without excess backlash.
A SAE-C four-bolt front flange provides a common mounting interface to engines or electric motors, and SAE O-ring housing ports minimize external leakage at static joints. The inlet uses a two-inch four-bolt split flange that permits low-restriction oil supply, whereas the outlet employs a one-inch four-bolt split flange sized for rated flow at working pressure. A single Viton shaft seal retains case fluid while tolerating elevated oil temperatures common in mobile equipment. These connection and sealing features simplify installation and ensure reliable service in open circuit hydraulic systems.
