The nominal displacement of the KYB PSVD2-21E-20 pump is approximately 21 cm³/rev. As a key parameter, it determines the volume of hydraulic fluid the pump can move in one full rotation of its internal components, which is crucial for meeting the flow requirements of the Yanmar 55 excavator's hydraulic system for various operations like boom lifting, arm movement, and bucket actions.
Operating Pressure
As a main pump for an excavator, it is designed to operate at relatively high pressures. The maximum operating pressure for this pump is likely to be in the range of 200 bar (20 MPa) to 350 bar (35 MPa). This pressure range enables it to provide sufficient power to drive the hydraulic cylinders and motors of the Yanmar 55 excavator, allowing for efficient digging, lifting, and maneuvering.
