Excavator E330D PUMP Parts 2667954 2478992 TQ Hydraulic Pump Construction Machinery Parts

The hydraulic pump is a vital component in excavators, converting mechanical power into hydraulic energy to operate cylinders, motors, and other actuators. It ensures efficient power transmission, enabling precise control and high performance in digging, lifting, and material handling applications.

Hydraulic pumps function through positive displacement, where mechanical rotation forces fluid movement. The process involves:

• Suction: Drawing fluid into the pump chamber.

• Compression: Pressurizing the fluid by reducing chamber volume.

• Discharge: Delivering high-pressure fluid to the hydraulic circuit.

Common pump types:

• Gear Pumps – Robust and economical for medium-pressure systems.

• Piston Pumps – High-pressure, high-efficiency performance.

• Vane Pumps – Smooth flow with moderate pressure output.
