Product Description

This gear pump is a pre-actuating gear pump (oil replenishment pump) specifically designed for the E305.5, E306, E312C, E320, E330C, and E336D series excavators. It is an essential auxiliary power component in the entire hydraulic system of the machine, primarily responsible for outputting stable pre-actuating oil pressure and providing control pressure to the control handle, distribution valve, and hydraulic main pump.

The pump body is made by casting a high-toughness alloy cast iron as a single piece. The overall strength of the product is controlled from the raw material level, which can withstand high-frequency pressure impacts and effectively avoid the potential failure of pump shell deformation and cracking under long-term high-pressure load conditions. The internal transmission gears are processed by high-precision hobbing and grinding, with strict control of gear meshing clearance, minimizing gear operating friction loss and reducing internal leakage of hydraulic oil, ensuring long-term stable volumetric output efficiency.

The entire sealing kit is made of high-performance sealing materials that are resistant to oil, aging, and high temperatures. It can withstand long-term high-temperature hydraulic oil flushing and effectively solve common problems such as end face oil leakage and shaft head oil leakage that occur with ordinary accessories. It can easily cope with various complex and harsh working conditions in outdoor construction sites, such as heavy dust, large environmental temperature differences, and inconsistent quality of hydraulic oil. Whether it is earthwork excavation, stone crushing, municipal infrastructure construction, or landscaping construction, it can maintain long-term stable operation and meet the high-strength operation requirements of medium and large-tonnage excavators.
