83012070

The 83012070 pump belongs to the Open Circuit Piston Pumps series manufactured by Danfoss for hydraulic automation where variable flow must be supplied to cylinders and motors. A displacement of 147 cm³/rev defines the volume delivered per shaft revolution, while clockwise rotation lets the unit couple directly to right-hand prime movers. The continuous pressure capability of 260 bar keeps work functions operating under sustained load, and a pressure compensator preset to 250 bar limits peak outlet pressure to protect downstream components. A 20 bar load-sense setting establishes the pressure differential that directs the swashplate to adjust flow only when the circuit demands it. A single Viton shaft seal contains high-temperature hydraulic oil at the drive end, and the SAE-C 4-bolt front flange provides a standard mounting interface on mobile or industrial gearboxes.

Mechanical power is transmitted through a 17-tooth, 12/24-pitch shaft spline that aligns with common splined couplings, and the shaft can accept up to 452 N·m of torque without slippage. The inlet port uses a 4-bolt split flange sized at 2.5 in with a 0.5 in thread to ensure low restriction oil supply, whereas the outlet port employs a 4-bolt split flange of 1.25 in with the same thread size to handle high-pressure discharge lines. These flanged connections speed up hose installation and maintain sealed joints under vibration. Together, the mounting, drive, and port features allow the 83012070 pump to integrate quickly into open-loop hydraulic systems that require reliable flow and pressure control.
