Product Description

This gear pump is suitable for multiple large-tonnage excavators such as E330D, E336D, JS330, JS360, and JS460. It is a crucial oil supply component in the overall pilot hydraulic system of the machine, responsible for continuously and stably delivering pressure oil to the pilot control circuit, providing fundamental power support for the control handle, main control distribution valve, traveling and rotation mechanisms.

The pump body shell is made by a thickened high-strength aluminum alloy through a single-piece die-casting process, resulting in a higher overall structural strength. It has excellent resistance to vibration, impact, and deformation, and can long-term adapt to the harsh working conditions in mines and construction sites, such as high dust, strong vibration, and large temperature differences between day and night. This effectively avoids the risk of pump shell cracking and deformation. The internal core transmission gears and drive spline shafts are all made of high-quality alloy steel raw materials. They undergo high-precision gear hobbing, precise grinding, and overall heat treatment processes, significantly enhancing the hardness and wear resistance of the tooth surfaces, precisely controlling the gear meshing clearance, and reducing mechanical wear and internal volume leakage during high-speed operation of the gears. The built-in complete sealing components use imported high-quality oil seal materials resistant to high pressure, high temperature, and hydraulic oil corrosion. Even when the equipment operates at full load for a long time and the hydraulic oil temperature continuously rises, it can still maintain a good sealing effect, effectively reducing oil leakage and seepage at the pump body joints and oil ports, effectively extending the overall service life of the gear pump and reducing the frequency of component replacements.
