Product Description

This hydraulic gear pilot pump is specifically designed for the EC290B, EC300D, R210LC-7, and R250LC-7 models of excavators. It is a crucial auxiliary oil supply component in the entire hydraulic system of the machine, mainly responsible for replenishing oil in the pilot control circuit and providing stable pilot pressure. It supplies sufficient and stable hydraulic power sources to the main hydraulic pump, distribution valve, and control handle.

The pump body shell is made of high-strength aluminum alloy and is formed by a single-piece die-casting process. This design not only reduces the weight of the pump body but also ensures that the shell is resistant to impact, less prone to cracking or deformation, and can adapt to the harsh working conditions of construction sites with high dust, strong vibrations, and large temperature differences. The core transmission gears and drive spline shafts are made of high-quality alloy steel and undergo precise gear hobbing processing and overall heat treatment. The hardness of the gear tooth surface is uniform, the gear tooth shape tolerance is strictly controlled, the meshing clearance is precisely controlled, effectively reducing the wear rate of the gears during high-speed operation, and significantly reducing internal leakage of the pump body. The internal sealing components are selected from rubber sealing components with high-pressure resistance, oil resistance, and high-temperature resistance, which can withstand continuous working oil pressure for a long time and are less likely to experience oil seal aging and oil leakage or seepage. This reduces the probability of early damage to the components from the raw material source.
