Danfoss Frame K Open Circuit Axial Piston Pump Series 45 is a open circuit piston pumps that convert input torque into hydraulic power. Their rotational force is transmitted through the input shaft to the cylinder block, and the input shaft is supported by tapered roller bearings at the front and rear of the pump and is splined into the cylinder block. These pumps are specially developed for mobile equipment to provide optimum performance and precise control.

These pumps are available with variety of control system options including load sensing and pressure compensated, which makes them ideal in numerous mobile equipment. Danfoss Frame K features through-drive capability for multi-circuit systems that makes them versatile and used in Cranes, Telescopic handlers, Forklift trucks, Wheel loaders, Sweeper, Backhoe loaders etc. Furthermore, with their compact size, mounting flanges, shafts, and porting options, they are easy to install.

With the nominal pressure up to 210 [3045 psi] bar and maximum pressure up to 350 [5075 psi] bar, Frame K pumps are constructed in sizes 38 cm³ and 45 cm³. Danfoss Frame K Open Circuit Axial Piston Pump Series 45 have control ports system pressure to the servo piston, adjusting swashplate angle to control pump output flow. These pumps are popular for longer service life and high performance thanks to their robust input shaft bearings to handle large external shaft loads and Integrated gauge ports for monitoring operating conditions.
