The 83014327 piston pump belongs to the Open Circuit Piston Pumps series and is manufactured by Danfoss for hydraulic automation that requires variable flow control. It displaces 147 cc per revolution, supplying the volume needed for medium-to-large actuators. Counter-clockwise rotation matches engine PTO layouts that turn opposite to standard shafts. A pressure compensation setting of 250 bar limits outlet pressure by reducing swash-plate angle, while a 25 bar load sensing differential keeps flow proportional to circuit demand. Response speed is defined by a standard gain orifice, avoiding the need for field tuning. A single Viton shaft seal contains fluid under elevated temperatures encountered in continuous service. The absence of an auxiliary flange means additional pumps cannot be mounted in tandem on the rear housing.
A SAE-C 4-bolt front flange secures the pump directly to diesel engines or gearbox pads. Radial port orientation arranges all hydraulic lines around the case, reducing overall package depth in crowded engine bays. The inlet uses a 2.5 in 4-bolt split flange to lower suction velocity, whereas the outlet is a 1.25 in split flange sized for full rated flow. Continuous operation is permitted up to 260 bar, giving a safety margin above the compensation threshold. Housing ports with SAE O-ring threads provide sealed connections for case drain and flushing. Because no choke orifice is fitted, external damping devices must handle transient pressure spikes.
