83013229

The 83013229 open-circuit piston pump belongs to the Open Circuit Piston Pumps series from Danfoss and supplies regulated hydraulic flow for automated machinery. It uses pressure-compensated, load-sensing control so circuit flow and pressure adjust automatically to changing actuator demand. A maximum displacement of 130 cm³ per revolution supports high output for large cylinders or motors, and counterclockwise rotation matches engines that drive pumps from the flywheel side. The pump sustains a continuous pressure of 310 bar during duty cycles, while the pressure-compensation valve limits outlet pressure to 250 bar to protect downstream components. Its load-sensing port opens at a 20 bar differential, allowing precise flow trimming when multiple functions share the same supply.

Mechanical mounting and line connections follow SAE standards to simplify installation. A four-bolt SAE-C front flange aligns the housing on gearboxes, and an auxiliary SAE-C 14-tooth shaft flange accepts a secondary pump for tandem layouts. Fluid enters through a 2.5 in split-flange inlet that minimizes suction losses, and delivery exits the 1.25 in split-flange outlet for compact hose routing. The complete assembly weighs 54.9 kg, providing the rigid mass needed to support internal bronze bearings and resist vibration in mobile or industrial frames.
