A10VG28EP3D2/10R-NSC10F025SP Hydraulic Piston Pump for Rexroth Concrete Pump Truck

A10VG series is swash-plate type axialvariable piston pumps used for hydrostatictransmission in closed circuits.The flowrate is proportional to drive speed anddisplacement.And it can be infinitelyadjustable.The output flow increases fromzero to maximum with swash plate swing Angle.The swash plate can change the direction ofliquid flow smoothly when it is placed in themiddle position.Each high-pressure side isequipped with two relief valves to preventhydraulic overload.The overflow valve also hasthe function of filling oil.The charge pump isused for oil supply and control pump

The axial piston variable displacement pump with inclined plate structure is suitable for closed loop hydrostatic transmission. The flow rate is proportional to the driving speed and displacement, and can be infinitely adjusted. As the inclined plate swing angle increases, the flow rate ranges from zero to the maximum value. When the inclined plate swings past the zero position, the direction of fluid flow smoothly changes direction. Multiple forms of control and regulation functions with good adaptability. The two relief valves on the high-pressure side protect the hydraulic transmission components (pump and motor) from overload.

The high-pressure relief valve also serves as an oil replenishment valve,

Limit the maximum oil replenishment pressure through the built-in oil replenishment overflow valve.
