The 83012894 pump belongs to the Open Circuit Piston Pumps series manufactured by Danfoss for hydraulic automation systems that require variable flow under changing load conditions. It delivers 178 l/min at rated speed, ensuring consistent actuator motion in mobile machinery. A continuous input speed limit of 2400 rpm permits long duty cycles, and a continuous pressure rating of 310 bar supplies adequate force to cylinders and motors. Pressure-compensating and load-sensing control maintains efficiency by trimming displacement as demand shifts. The pump attaches using an SAE-C 4-bolt front flange, while fluid enters through a 2 in 4-bolt split flange inlet with a 0.5 in thread that accommodates high-volume suction lines. Clockwise rotation aligns with common engine outputs, and a 30 bar load-sense setting sustains the differential pressure needed for stable downstream flow.
The unit tolerates a maximum input speed of 2800 rpm for short bursts, and its 74 cc per revolution displacement provides ample volume when the swash plate reaches full stroke. Each bar of pressure requires 1.178 N·m of drive torque, giving designers a clear basis for sizing prime movers and couplings. Circuit safety is upheld by a 400 bar maximum pressure ceiling, and the pressure compensator set at 170 bar retracts the swash plate once working pressure is achieved. Discharge oil leaves through a 1 in 4-bolt split flange outlet with a 0.375 in thread, matching standard manifold connections. A single Viton shaft seal prevents external contamination and retains hydraulic fluid during pressure spikes, rounding out the pump’s features for open-circuit automation tasks.
