Product Descriptio

This main hydraulic pump is specifically developed for the EX100-5, EX120-5, EX130, and EX135 series excavators. It is the core power unit of the entire hydraulic system and adopts the same specification variable piston pump structure design. The installation flange, oil port position, connection spline, and control interface are all fully in line with the original vehicle standards. There is no need to modify the pipelines and brackets, and it can be directly replaced with the original hydraulic pump, perfectly adapting to the power output characteristics of these models. It is an excellent replacement part for equipment major repairs and old pump damage replacement.

The pump body itself is made by casting high-strength ductile iron as one piece, and undergoes stress relief heat treatment process. This can effectively resist continuous vibration, high-pressure impact, and temperature changes, causing deformation. The shell has high strength and excellent anti-leakage ability. It is stable and reliable in harsh working conditions such as earth excavation, crushing operations, and heavy-load climbing. The core friction pairs such as the piston, cylinder, flow distributor, and return disc are all made of high-maintenance alloy materials, combined with ultra-precision grinding processing technology. The friction pair fitting accuracy is high, and the oil film remains stable under high-pressure conditions, significantly reducing internal leakage in the pump body. It can maintain the rated flow and output pressure for a long time, effectively improving common faults such as weak digging machine operation, slow speed, stuck compound actions, rapid increase in hydraulic oil temperature, etc.
