Sandvik 55039471 Double Gear Hydraulic Pump

Sandvik 55039471 Double Gear Hydraulic Pump is a durable hydraulic pump used in the pump assemblies of various Sandvik and Tamrock drilling machines. In contrast to the piston pumps for high-pressure and variable-flow applications, this pump features an external double gear pump design and can therefore be used in functions requiring constant oil supply, straightforward and reliable construction in tough mining conditions.

Two hydraulic pump components can be operated by the same drive with the double gear mechanism, enabling supply of separate hydraulic functions in the machine. This solution is frequently applied when stable flow rate is more significant than variable displacement control. Due to the simple and solid construction of the 55039471 pump, it can work effectively in continuous drilling when the oil is clean and the system is properly maintained.

The Sandvik 55039471 hydraulic pump is utilized in various drilling machines, including the following models: DD321, DD421, DS410, DS411, DS420, DS421, DL421, DL430, DT621, DT721, DT820, DT821, DT921i and DX700. Moreover, the 55039471 hydraulic pump is specified in some Axera machines and other Sandvik/Tamrock drilling rigs. Therefore, the 55039471 pump is perfect choice for a wide range of application.

Rexton Hydraulic supplies, repairs and services the Sandvik hydraulic pumps for underground and surface drilling machines. The Rexton Hydraulic team can assist you in getting the Sandvik 55039471 Double Gear Hydraulic Pump to replace or repair the pump along with inspection of the hydraulic spare parts. During the repair process, the pump gears, shafts, bearings, bushings, seals, housing surfaces, and internal clearance can be checked for any wear before rebuilding the pump and conducting the test.

One of the advantages of this pump design is simplicity of the internal structure when compared with variable piston pumps. But the right internal clearance is very important since wear of the gear and housing can cause the internal leakage and low hydraulic fluid output. It means that proper inspection is required before determining the course of action.
