The nominal displacement of the K3V63DT - 9N3D - 14 pump is 63 cm³/rev. As a variable displacement pump, the actual displacement can be adjusted within a certain range according to the hydraulic system's needs of the CAT312 excavator. This adjustment helps in matching the flow demands for various functions such as boom lifting, arm movement, and bucket operation
These pumps are designed to operate at high pressures to power the hydraulic system of the CAT312 excavator. The maximum continuous operating pressure can typically reach around 350 bar (35 MPa). However, the exact maximum pressure may vary depending on the specific operating conditions, control settings, and the overall design of the pump for the CAT312 model.
