OEM Rexroth A7V20LV1 A7V28LV1 A7V40LV1 A7V55LV1 Hydraulic Pump | Partsdic®

The A7V series pumps are axial piston variable displacement pumps, which means they offer adjustable flow rates to meet the specific requirements of the hydraulic system.

They are suitable for both open and closed-loop circuits and can operate in a wide range of pressures and speeds. These pumps are commonly used in construction machinery, industrial machinery, and mobile equipment.

The A7V20LV1 is the smallest pump in the series, with a displacement of 20 cc per revolution. It is compact and lightweight, making it ideal for applications where space is limited. The A7V28LV1 offers a displacement of 28 cc per revolution, providing a slightly higher flow rate compared to the A7V20LV1. This makes it suitable for applications that require increased hydraulic power.

Moving up the series, the A7V40LV1 has a displacement of 40 cc per revolution. This pump offers even greater flow rates and is commonly used in larger machinery and systems. Finally, the A7V55LV1 has a displacement of 55 cc per revolution, making it the largest pump in this particular series. It provides significant hydraulic power and is capable of handling demanding applications that require high flow rates.

All the pumps in the A7V series feature a swashplate design, where the axial pistons are positioned at an angle to the drive shaft.

This design enables smooth and efficient operation by converting the rotational motion of the drive shaft into linear motion of the pistons. The angle of the swashplate determines the displacement and, consequently, the flow rate of the pump.

These Rexroth pumps are known for their high efficiency, precise control, and low noise levels. They incorporate advanced hydraulic technologies and high-quality materials to ensure optimal performance and durability. The pumps are built to withstand demanding operating conditions, including high pressures and temperatures.

Additionally, the A7V series pumps are equipped with various control options, allowing for flexible and precise adjustment of the flow rates. They can be controlled manually or electronically, depending on the specific requirements of the application. The pumps also offer a wide range of mounting options to facilitate easy integration into different hydraulic systems.

Maintenance and service of these pumps are relatively straightforward. Regular inspection and timely replacement of components, such as seals and bearings, are recommended to ensure optimal performance and longevity. Rexroth provides comprehensive technical support and a global network of service centers to assist customers with any maintenance or repair needs.
