Excavator CX210B KRJ17131 pump assy K3V112DP-XDPR-9Y00 hydraulic main pump

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.

Maintenance

Regularly replace hydraulic oil and filter element to keep the oil clean.

Regularly check the noise, vibration, and temperature of the hydraulic pump, and promptly address any abnormalities found.

Avoid long-term overload work to prevent hydraulic pump overheating and damage.
