There is a minimum rotational speed below which the pump may not operate efficiently. For the AP2D18, the minimum speed is usually around 600 - 800 rpm (revolutions per minute). This is affected by factors such as the type of hydraulic fluid used and the initial operating conditions of the excavator's hydraulic system.
Maximum Speed
Exceeding the maximum speed can cause excessive mechanical stress and noise, and may lead to component failure. The maximum speed for the AP2D18 piston pump is typically around 2000 - 2500 rpm. The exact maximum speed should be obtained from the official Rexroth product information.
