English Product Introduction

708‑2K‑11152 hydraulic main pump assembly is OEM matching pump for Komatsu PC800‑8 and PC850‑8 large excavators. It fully conforms to original mounting dimensions, oil port layout and electronic plug interface, supporting direct replacement without modification on pipelines or wiring harness.

It adopts double variable piston structure equipped with high‑precision electronic load sensing control system. The displacement can be automatically adjusted according to excavation load. It supplies sufficient high‑pressure flow under heavy load and reduces displacement to save fuel under light load, balancing powerful performance and fuel efficiency.

The internal cylinder block, pistons and valve plates are made of high‑strength wear‑resistant alloy with precision grinding and heat treatment, featuring outstanding impact and abrasion resistance for long continuous heavy mining work. It effectively solves common pump failures including internal leakage, weak digging power, abnormal noise and overheating.

Full set of FKM high‑pressure sealing parts are equipped, which resist high temperature and hydraulic oil corrosion to avoid oil leakage during long‑hour continuous operation. Integrated cast pump housing delivers high structural strength against vibration and deformation.

Every pump undergoes complete hydraulic tests on pressure, flow and variable response before delivery with stable performance. As the core hydraulic replacement spare part for 80‑ton Komatsu mining excavators, it perfectly fixes machine issues such as slow movement, weak digging, engine choking and pressure drop.
