83012361

The 83012361 pump is part of the Open Circuit Piston Pumps series manufactured by Danfoss for hydraulic automation where stable oil flow is needed to actuate cylinders and motors. Its displacement of 130 cm3 per revolution determines the volume delivered each shaft turn, allowing designers to calculate flow at a given speed. The unit sustains a continuous pressure of 310 bar so it can drive heavy-duty work circuits without derating. Clockwise rotation matches common engine flywheel directions and simplifies mounting. Power is transmitted through a 14-tooth 12/24 pitch spline input shaft, and the housing is rated to withstand 800 N·m of torque at that interface. A Viton seal is fitted to resist high temperature and synthetic hydraulic fluids while minimizing leakage.

Pressure compensated control keeps the outlet at a set level, and on this model the compensator begins to reduce displacement at 140 bar to prevent excess load on downstream components. A 1.0 mm gain orifice shapes the feedback flow so the pressure response remains stable rather than oscillatory. The suction line connects to a radial four-bolt split flange inlet sized at 2.5 inches, which reduces pressure drop on the pump’s intake. Discharge oil exits through a radial four-bolt split flange outlet measuring 1.25 inches for convenient routing to manifolds. For auxiliary functions, an SAE-C 14-tooth pad is provided to drive a secondary attachment such as a charge pump or low-power accessory without adding another prime mover.
