The 83014291 pump belongs to the Open Circuit Piston Pumps series and is manufactured by Danfoss for hydraulic automation where variable flow must be supplied to mobile or industrial actuators. Pressure compensation and load-sensing control enables the pump to match output to demand, improving system efficiency. A displacement of 130 cm³ per revolution defines the volume of oil moved each shaft turn. The theoretical flow reaches 286 L/min so large cylinders or motors can be driven without auxiliary boosters. A continuous speed rating of 2200 rpm states the maximum shaft rotation allowed during uninterrupted operation. The continuous pressure capability of 310 bar supports steady working loads common in construction equipment. A maximum pressure limit of 400 bar gives headroom for transient spikes without risking damage. The pressure-compensation setting is fixed at 250 bar while the load-sensing margin is 20 bar, ensuring stable circuit pressure and quick response to load changes.
The 14 tooth 12/24 pitch shaft spline interfaces with standard SAE drive couplings for torque transmission. A single Viton shaft seal keeps hydraulic fluid inside the housing and tolerates high oil temperatures. Clockwise rotation aligns with engines or gearboxes that turn in the same direction. The SAE-C 4-bolt front flange provides a rigid mounting face that resists misalignment. A 2.5 in 4-bolt split inlet port allows unrestricted fluid entry from the reservoir. A 1.25 in 4-bolt split outlet port connects to the pressure line while maintaining uniform bolt loading. Housing ports machined for SAE O-ring fittings reduce external leakage paths. The assembled unit weighs 54.9 kg, so lifting equipment may be required during installation.
