Sandvik 88756059 Variable Displacement Hydraulic Double Pump

Sandvik 88756059 Variable Displacement Hydraulic Double Pump is a high-strength axial piston pump assembly utilized in certain types of Sandvik and Tamrock surface drilling machinery. Its design comprises two variable displacement pumps mounted in one unit and enabling the provision of varying flow rate to multiple functions within the hydraulic system driven by one engine.

The 88756059 pump is often related to the A10VO hydraulic pump series. Two configurations are usually found for this pump, including the A10VO71 + A10VO45 and A10VO71 + A10VO71 ones. Since there is more than one configuration in use for one Sandvik reference number, the correct pump setup must be determined prior to the purchase.

The Sandvik 88756059 hydraulic double pump is used in certain Sandvik surface drilling rigs such as Ranger 600, Ranger 680, Ranger 700 and Ranger DX700 models. In these machines, the pump serves for the generation of hydraulic power needed for drilling and other operations performed in these drilling rigs. The variable displacement design of the pump allows each pump section to adapt to the hydraulic requirements automatically and more efficiently than the constant output one.

The use of double pumps implies that the condition of both sections becomes crucial. The machine will demonstrate decreased performance in those hydraulic functions that are served by the damaged section, while the rest of the hydraulic functions can operate as usual. The signs of problems can include slow response, pressure loss, poor drilling performance, noise, overheating or decreased output as the oil is warmed up to its operating temperature.

Rexton Hydraulic provides services on Sandvik hydraulic pumps used for mining and drilling operations. We also provide sales and part replacements of the Sandvik 88756059 pump. In the repair process, the condition of the internal components of both pump sides will be inspected, including the rotating units, pistons, cylinder blocks, valve plates, bearings, shafts, seals, and control units. All the worn-out parts will be repaired or replaced based on their condition prior to pump testing.
