83012243

The 83012243 pump is part of the Open Circuit Piston Pumps series and is manufactured by Danfoss for hydraulic automation tasks that require steady variable flow. Its displacement is 100 cc per revolution, delivering a defined volume each shaft rotation to drive cylinders or motors efficiently. Clockwise rotation aligns the pump with prime movers wired for that direction, simplifying coupling. A pressure-compensated control automatically trims the swashplate angle to keep outlet pressure constant under changing load. The pressure compensation is set at 240 bar, so flow is reduced once that threshold is reached to protect downstream components. Maximum continuous pressure is 310 bar, establishing the upper working limit for the housing and internal parts. A max-flow displacement limiter caps swashplate travel to prevent overspeed when demand is low. A 2.5 inch inlet port admits ample oil and lowers inlet velocity to reduce cavitation, while a 1.25 inch outlet port matches common pressure line sizes in mobile machinery.

A SAE-C four-bolt front flange lets the 83012243 mount directly to gearboxes or engine pads without adapter plates, saving installation time. SAE O-ring housing ports seal against hydraulic leaks and withstand repeated line servicing. The drive shaft carries 17 involute teeth that transfer torque evenly, and a 12/24 pitch defines their spacing for accurate spline engagement with couplings. A Viton shaft seal withstands elevated temperature and resists petroleum-based fluids, maintaining oil retention at the drive end. The radial endcap design supports side loads generated by high system pressure and keeps internal passages short. An auxiliary flange with 9 teeth provides a secondary take-off for tandem accessories. Threaded ports measuring 0.5 inch accommodate case drain or sensor fittings, allowing condition monitoring and fluid return to the reservoir.
