The hydraulic pump is a critical component that obtains power from the engine and converts it into hydraulic oil flow. This high-pressure fluid moves your boom, arm, bucket, and swing with incredible force and precision through hoses. Without a sturdy and reliable pump, even the strongest excavator will become sluggish and powerless. Choosing the right pump is not only about power; This is about perfectly matching the capacity and pressure rating of the pump with the size and typical operation of the machine. A pump that is too small in size will struggle, overheat, and quickly wear out. An excessively large pump wastes the power and fuel of the engine. This is the core of efficiency and productivity.

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.
