Shop REXROTH A4VG71 A4VG71EP Hydraulic Axial Piston Pump | Partsdic®

The A4VG71 pump is part of the A4VG series, which is known for its exceptional efficiency and durability.

It is specifically designed to handle high-pressure hydraulic systems and offers excellent power density. The A4VG71EP model is a variant of the A4VG71, designed with an additional auxiliary pressure port.

One of the key features of the A4VG71 A4VG71EP pump is its axial piston design. It consists of a rotating cylinder block with several pistons arranged in a radial pattern. These pistons move back and forth in response to the rotation of the cylinder block, creating a pumping action. The axial piston design allows for smooth and efficient operation, delivering high flow rates and maintaining consistent pressure levels.

The A4VG71 A4VG71EP pump is capable of operating at high pressures, making it suitable for demanding applications that require reliable and precise hydraulic power. It offers a maximum pressure rating of up to 350 bar, allowing it to handle heavy-duty tasks with ease. Additionally, it has a wide displacement range, providing flexibility in meeting various flow rate requirements.

Another notable feature of the A4VG71 A4VG71EP pump is its variable displacement capability.

This means that the pump can adjust its output flow according to the system's requirements. The displacement adjustment is achieved by changing the angle of the swash plate, which controls the piston stroke length. This feature allows for energy-efficient operation by matching the pump output to the load demand, reducing energy consumption and improving overall system efficiency.

The A4VG71 A4VG71EP pump also incorporates advanced control options, such as load-sensing and pressure compensating functions. These features enable the pump to optimize its performance based on the system's needs, providing precise control and improving operational efficiency. The load-sensing function adjusts the pump's output based on the load demand, while the pressure compensating function maintains a constant pressure level regardless of the load variations.

In terms of construction and materials, the A4VG71 A4VG71EP pump is built to withstand demanding operating conditions. It features high-quality components and robust construction, ensuring durability and long service life. The pump's housing is made of rugged materials to resist wear and corrosion, while the pistons are designed for optimal sealing and efficiency.
