Model: PVD - 2B - 42P. It is a piston - type hydraulic pump, suitable for various small - to - medium - sized excavators such as YC35, PC40, EX40, and ZX40.
Weight: Approximately 25.6 kg5.
Origin: Usually from Japan7.
Warranty: Generally, it comes with a 1 - year warranty1.
Performance Parameters
Displacement: Although the specific displacement value is not publicly available, for similar models, it is estimated to be around 40 - 50

Pressure
Rated Pressure: It can reach 20 - 25 MPa, which can meet the normal working pressure requirements of the hydraulic system of relevant excavators.
Peak Pressure: It can generally withstand 25 - 30 MPa, providing a certain margin for the operation of the hydraulic system under special circumstances.
Flow: The flow capacity is related to the rotational speed of the pump and the displacement. Under the rated working conditions, the flow rate is estimated to be about 100 - 120 L/min. This flow rate can ensure the normal operation of each actuator of the excavator, such as the boom, arm, bucket, and swing mechanism.
