Product Description
Rexroth A4VG180 oil pump Double pump hydraulic piston pump
Rexroth A4VG180 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.
