Product Descriptio

This main hydraulic pump, designed to be compatible with large-tonnage excavators such as DX420, DX420LC, DH400LC, and R450LC, is the core power source of the entire machine's hydraulic system. It is responsible for providing hydraulic power to the entire set of mechanisms including the boom, dipper stick, bucket, rotation, and travel, directly determining the digging force, operation speed, heavy-load performance, and fuel consumption level of the entire machine.

This main pump is of a variable piston structure, strictly meeting the installation dimensions, flange base, oil inlet and outlet ports, and electromagnetic valve interface requirements. It perfectly matches the original vehicle's installation position without the need for modifying the pipelines or drilling and reworking. It can be directly replaced and installed, significantly reducing the maintenance and disassembly time, and is highly suitable for various maintenance scenarios such as large-scale repairs, old machine refurbishment, and upgrading the entire machine's hydraulic system. The pump body shell is made of high-strength casting material. The internal pistons, cylinder bodies, flow distribution plates, and valve sleeves, as well as other key moving components, undergo high-precision grinding processing, possessing excellent shock resistance and wear resistance. It can cope with high-intensity and harsh working conditions such as mining, earth and rock stripping, rock crushing, and heavy-load earthwork, effectively avoiding common faults such as internal leakage, pressure attenuation, and insufficient flow under long-term heavy-load operation, ensuring the continuous and stable output of power by the large-digging equipment.
