Product Description

This series of multi-model gear pumps are high-quality hydraulic supply components specially designed by GVO for the WA series of large-wheel wheel loaders. They are compatible with multiple mainstream loader models such as WA380-6, WA380-7, WA470-6, WA470-7, WA480-6, and WA380Z-6. They are mainly responsible for the oil pressure supply of the main control oil circuit, steering assist oil circuit, and bucket auxiliary oil circuit of the entire machine. They are the core hydraulic components that enable the operation of the loader's steering control, boom lifting, and bucket retraction and extension actions.

In terms of the selection of internal components and the fine processing technology, the driving gear, driven gear, and spline transmission shaft of this WA loader series gear pump are all made from high-hardness alloy steel forgings. They undergo multiple CNC precision hobbing, mirror surface grinding of the gear surface, and quenching and tempering hardening treatments. The gear tooth shape is highly accurate, the meshing is tight and smooth, which can reduce the impact noise during gear engagement and lower the internal leakage loss under high-pressure conditions.

The wear-resistant side plate and pressure pad on the inner side of the pump cavity are made of anti-wear composite materials, which can resist the long-term frictional wear caused by sand and stone impurities in the construction site hydraulic oil. The main shaft position is equipped with a high-pressure and high-temperature resistant rubber oil seal and multiple layers of buffer sealing components, which can withstand the long-term erosion of high-temperature hydraulic oil under heavy-load operations. The oil seal is unlikely to experience aging, hardening, cracking, or oil leakage faults. The entire pump body is cast with a dense structure, has outstanding pressure-bearing capacity, and even if it is in a high-pressure oil supply condition for a long time, the pump body will not have problems such as oil leakage from the shell or deformation of the pressure-bearing structure, ensuring the sealing performance of the entire hydraulic oil circuit for a long time.
