83012527

The 83012527 pump belongs to the Open Circuit Piston Pumps series and is manufactured by Danfoss for hydraulic automation duties in mobile and industrial machinery. A displacement of 74 cc per revolution establishes the volumetric output available to downstream circuits. Pressure-compensated, load-sensing control adjusts the swashplate angle to maintain target flow and pressure automatically. Counter-clockwise rotation matches prime movers that turn in that direction. The 14-tooth, 12/24 pitch shaft spline transmits torque to the rotating group without slipping, while a single Viton shaft seal prevents external leakage along the drive shaft. A 2-inch inlet port allows the required low-velocity suction flow, and the unit tolerates a continuous pressure of 310 bar on the outlet side during sustained operation.

Hydraulic connections are completed through a 1-inch outlet port sized for the rated pressure and flow, and all housing ports use SAE O-ring fittings to simplify leak-free service access. An SAE-B auxiliary flange with 13 teeth is provided for mounting auxiliary drive devices. A 0.3 mm bleed orifice purges trapped air from the case to maintain stable control response. The load-sensing circuit is adjusted to 10 bar, permitting efficient standby operation when system demand is low, while the pressure-compensation setting is fixed at 100 bar to trigger swashplate de-stroke and protect the system from over-loading. Together these features integrate the pump into open-circuit systems that require accurate flow regulation and dependable performance under varying load conditions.
