AP2D28: The nominal displacement is 28 cm³/rev. This value determines the volume of hydraulic fluid the pump can move in one full rotation of its shaft, which is crucial for providing the necessary pilot pressure in the hydraulic systems of the mentioned excavators.

AP2D25: The nominal displacement is 25 cm³/rev. It serves a similar function in the hydraulic circuits of the Doosan and Kubota excavators, supplying pilot fluid to control various hydraulic functions.

Operating Pressure

These pilot pumps are designed to operate at relatively lower pressures compared to the main hydraulic pumps in excavators. The maximum operating pressure for the AP2D28 and AP2D25 pumps is typically in the range of 20 bar (2 MPa) to 50 bar (5 MPa). This pressure range is sufficient to actuate the pilot valves and control the flow of hydraulic fluid in the main hydraulic system, enabling smooth operation of functions such as boom, arm, and bucket movements.
