Product Description

This gear pump is a crucial pilot gear pump that is specifically designed for the hydraulic system of the E330D and E336D excavators. As a supplementary supply component for the main hydraulic pump, it is mainly responsible for delivering pressure oil to the entire machine's pilot control circuit, providing stable pilot oil pressure to the control levers, electromagnetic valves, and distribution valves, and directly determining the sensitivity of the vehicle operation, the response speed of the action, and the smooth operation of the hydraulic system.

The pump housing is made of high-strength aluminum alloy through precision die-casting. It is lightweight overall and has a strong structural rigidity, which can well withstand the frequent pressure shocks in the hydraulic circuit. It also has excellent heat dissipation performance, which can alleviate the pump body temperature rise caused by the long-term high-load operation of the excavator. The internal core transmission gears are made of high-quality alloy steel and undergo multiple precise processing techniques such as high-precision hobbing, vacuum heat treatment quenching, and mirror surface grinding. The gear tooth shape is highly accurate, the tooth surface hardness is uniform, the gear meshing operation is smooth and stable, the oil pressure pulsation amplitude is small during operation, the output flow is continuously stable, and it significantly reduces the wear speed between gears under high-speed operation conditions. The pump body is equipped with imported quality sealing components and wear-resistant bearings. The sealing components have excellent resistance to hydraulic oil corrosion, high temperature, and aging, and can adapt to the long-term high-temperature environment of hydraulic oil, effectively avoiding frequent faults such as oil leakage on the pump body side and oil leakage at the shaft head. The wear-resistant bearings can buffer the vibration impact caused by equipment operation, reduce eccentric wear of the main shaft, and effectively extend the service life of the gear pump on the whole.
