Rexroth A4VG28 A4VG40 A4VG56 A4VG71DA1D7 A4VG90 A4VG125 A4VG180 A4VG250 Hydraulic oil pump Piston Pump 

It offers several key features for efficient and versatile operation:


Infinitely Variable Flow: Flow rate directly correlates with drive speed and pump displacement, allowing for smooth adjustments.

Wide Flow Range: The pump can deliver flow from zero to its maximum capacity by varying the swash plate angle.

Reversible Flow Direction: Tilting the swash plate beyond the neutral position seamlessly reverses the fluid flow direction.

Flexible Control Options: The pump supports multiple control methods (NV, DG, EZ, HD, HW, EP, DA) for compatibility with diverse control and regulation systems.

Internal System Protection: Two integrated Relief valves on the high-pressure side safeguard the hydrostatic transmission (pump and motor) against excessive loads. Notably, the high-pressure relief valve also functions as an oil filling valve.

Integrated Auxiliary Pump: An internal auxiliary pump serves as both a Charge Pump and a control pump, simplifying the system design.

Built-in Pressure Relief: A dedicated charging relief valve limits the maximum charging pressure.

Pressure Shut-off Valve: All models come equipped with an integrated pressure shut-off valve for additional system control.
