PC35MR-2 Hydraulic Main Pump Assembly for Komatsu Mini Excavator Hydraulic Piston Pump Spare Parts

The PC35MR-2 Hydraulic Main Pump Assembly is a replacement hydraulic component designed for compatible Komatsu PC35MR-2 mini excavator applications.

Also known as an Excavator Main Hydraulic Pump, Hydraulic Pump Assembly, Mini Excavator Hydraulic Pump, or Main Pump Unit, this component is designed to supply hydraulic fluid flow to the corresponding excavator hydraulic system.

As an important component of the excavator's hydraulic power system, the main pump converts mechanical power from the engine into hydraulic flow, supporting the operation of designated machine functions.

A correctly matched and properly functioning hydraulic pump helps maintain the equipment's specified hydraulic performance and supports the operation of the boom, arm, bucket, travel, and swing systems through the corresponding hydraulic circuits.

The PC35MR-2 hydraulic pump assembly features a heavy-duty dark metallic housing, mechanical drive shaft, mounting flange, hydraulic connection ports, and integrated pump sections.

Its compact construction is intended for installation in compatible mini excavator hydraulic systems where available installation space and hydraulic system requirements must be considered.

JISION supplies excavator hydraulic pumps, hydraulic motors, control valves, and construction machinery replacement components to excavator owners, equipment repair workshops, construction contractors, and international spare parts distributors.
