EX55UR-3 Hydraulic Pump EX55UR-3 Main Pump 4310048 4403530 PSVD2-21

The PSVD2-21 hydraulic pump is a variable displacement axial piston pump that is commonly used in various hydraulic systems. It is designed to provide efficient and reliable operation in demanding applications.

The PSVD2-21 pump features a swash plate design, which allows for variable displacement control. This means that the pump can adjust its output flow rate and pressure to match the requirements of the system it is connected to. This feature is particularly useful in applications where the hydraulic system needs to adapt to changing load conditions.

The pump is capable of delivering a maximum displacement of 21 cc/rev, which determines its maximum flow rate. The displacement can be adjusted by changing the angle of the swash plate, which is controlled by an external mechanism such as a hydraulic servo or an electric actuator.

The PSVD2-21 pump is also equipped with a built-in pressure compensator, which helps maintain a constant pressure within the hydraulic system. This feature ensures that the pump delivers the required flow rate at a consistent pressure, regardless of changes in the load or system conditions.

In addition, the pump is designed for high efficiency, with low internal leakage and minimal power losses. This helps to optimize the overall energy consumption of the hydraulic system and reduce operating costs.

Overall, the PSVD2-21 hydraulic pump is a reliable and versatile solution for various hydraulic applications, offering variable displacement control, pressure compensation, and high efficiency.
