Excavator spare parts ZX850-3 ZX650-3 4635645 hydraulic pump assembly for K3V280
The hydraulic pump converts mechanical energy into hydraulic energy to power the excavator's hydraulic system. When the engine drives the pump shaft to rotate, the internal pistons or gear sets create oil suction and compression processes, forming a high-pressure oil flow. Belparts hydraulic pumps feature variable displacement design that automatically adjusts output flow according to load requirements, achieving high energy efficiency.

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 appliions.
Working Principle
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.
-
