Product Description

This hydraulic main pump is the core assembly of the power source for the hydraulic system of the E320B, E320C, and E320D excavators. It is also commonly referred to as a piston pump. All the hydraulic actions of the entire excavator are powered by this pump, converting the mechanical energy output by the engine into high-pressure hydraulic oil energy, providing pressure oil flow to the arm, boom, bucket, rotation, and travel motors. The digging force, action response speed, smoothness of compound actions, and equipment operation fuel consumption performance of the entire machine are all directly determined by the working state of the hydraulic pump.

This hydraulic pump adopts a dual-plunger pump integrated structure design. The pump body itself is formed by a single piece of high-strength cast iron through casting, and is completed through multiple processes such as precise machining, high-pressure oil circuit flushing, and pressure testing. The core friction components such as the internal plungers, cylinder bodies, flow distribution discs, and oscillators are made of high-quality wear-resistant materials, which are strengthened through quenching and heat treatment, and the mating surfaces are precisely ground to ensure high precision. The friction pair cooperation accuracy is strictly controlled, enabling it to withstand high-pressure and large-flow conditions for a long time, effectively reducing internal wear and high-pressure internal leakage problems. Even when continuously operating in high-intensity scenarios such as earthwork, mining, and heavy-load loading, it can maintain stable volumetric efficiency and reduce thermal engine weakness and slow action faults caused by pump internal leakage.
