Core Information

Function: Converts the mechanical energy from the engine into hydraulic energy, supplying high-pressure oil to the hydraulic system. This drives actuators like Cylinders and motors, enabling equipment functions such as lifting, steering, and movement.

Features: Utilizes gear meshing principles for suction and discharge, featuring simple structure, high reliability, and easy maintenance. Exhibits strong shock resistance and contamination tolerance, suitable for harsh construction conditions. Some models employ a dual-pump configuration to supply multiple hydraulic circuits simultaneously.

Applications: Commonly found in steering systems and working equipment hydraulic circuits.

Common gear pump failures include insufficient pressure, excessive noise, and oil leakage, often caused by gear wear, seal aging, or contaminated oil. Routine maintenance requires regular checks of hydraulic oil cleanliness and pump fastening status, while avoiding dry running and overload operation.
