Sandvik 56040321 Piston Hydraulic Pump

Sandvik 56040321 Piston Hydraulic Pump is an axial piston pump and it is used in the hydraulic system of selected Sandvik underground loaders. It is applicable to Sandvik LH514 and LH517 loaders that require reliable hydraulic power for loading, hauling and material handling operations. The pump must operate efficiently under tough underground conditions while providing consistent hydraulic flow and pressure during the entire operation period.

The 56040321 pump features axial piston design and thus is appropriate for use in high-pressure mobile hydraulic equipment requiring efficient operation and proper oil supply. During underground loader operation, hydraulic demands vary significantly depending on steering, lifting, tilting and other operations. Good working of the piston pump provides better response and reliability of machine operation during these repeated cycles.

On the LH514 and LH517, the Sandvik 56040321 pump is installed in the hydraulic pump assembly. The parts list of Sandvik also includes the corresponding adjuster for the 56040321 pump, so it is possible to say that the control mechanism is the essential part of hydraulic system of this machine. Proper adjustment of the pump is required because the wrong settings or wear of control parts may affect hydraulic response even if rotating parts are still in usable condition.

Rexton Hydraulic specializes in sales, repair, and servicing of Sandvik hydraulic pumps used in underground loaders, drilling machinery and mining machinery. Rexton Hydraulic offers repair services of the Sandvik 56040321 hydraulic pump. In the process of repair, internal vital components including the rotating group, pistons, cylinder block, valve plate, bearings, shaft, seals, and adjuster are thoroughly examined for wear and repaired depending on the condition of the pump.

Identification is necessary before replacement since pumps having an external appearance which may be alike will have differing controls, shafts, rotations, mounting flanges, and ports. It is therefore advisable to check the Sandvik part number 56040321, the model number of the machine, the serial number and the nameplate information of the pump before placing an order for replacement.
