The 83015102 pump belongs to the Open Circuit Piston Pumps series from Danfoss and supplies regulated hydraulic flow to mobile and industrial machinery. Its fixed displacement of 74 cc per revolution delivers a consistent volume for predictable circuit performance. A pressure-compensated control holds the outlet at its 310 bar setting, matching the 310 bar maximum continuous pressure so excess flow is automatically trimmed at the target value. Rotation is clockwise, aligning with common engine power-takeoff drives, while a 14-tooth 12/24-pitch splined shaft provides direct coupling to SAE hubs. Containment is handled by a single Viton shaft seal that withstands high oil temperature and chemical exposure. There is no choke orifice in the control path, but a standard gain orifice remains to set the response rate without external tuning.
Mechanical and port details support straightforward installation. A SAE-C four-bolt front flange secures the housing to gearboxes or mounting plates, and SAE O-ring port cavities simplify leak-free tube or hose connections. The inlet side uses a 2 in port with a 0.5 in thread to reduce suction restriction, whereas the outlet employs a 1 in port fitted with a 0.375 in thread for high-pressure line attachment. Because the design includes no displacement limiter, the full pump stroke stays available whenever system pressure is below the compensator threshold. Together, these interfaces allow the unit to integrate quickly into open-circuit layouts and deliver its rated flow without additional adapters or limit screws.
