Sandvik BG00849011 Gear Hydraulic Pump

Sandvik BG00849011 Gear Hydraulic Pump is a fixed-displacement hydraulic pump used on certain Sandvik drilling machines. Its purpose is to provide a constant supply of hydraulic oil for supporting machine functions in cases when a simple and reliable pump assembly is required. Gear pumps are suitable for continuous duty mining and drilling applications, providing constant flow and being fairly simple in terms of construction.

The Sandvik BG00849011 is used on the Sandvik DD311D underground drill rig, so the pump is an important reference point when replacing this equipment. In underground drilling machinery, it is important that the auxiliary hydraulic circuits work without failures during the whole operation process, and a working gear pump helps keep a constant reaction of the functions connected to this circuit.

The gear pump differs from a variable displacement piston pump, since it provides a fixed volume of oil flow depending on its displacement and rotation speed. That is why the proper pump sizing is critical. Otherwise, although the pump can be installed easily, it may provide too much or not enough hydraulic flow that may influence the system negatively and overload other hydraulic elements.

As the Sandvik BG00849011 Hydraulic Pump starts wearing down, users will experience slower performance, lower flows, increase in pump noise, and increase in hydraulic oil temperature or leakages from the shaft and housing. The internal wear of gears, bushings, and housing could increase the internal leakage in the pump, hence reducing the flow rate that will be available in the hydraulic circuit despite the pump running normally.

The gear pumps could provide extended life provided the hydraulic system is properly maintained, however, the presence of contaminated oil could bring about fast wear and damage of the internal surfaces. The contamination could result in scoring of the gears and housing, and restricted suction flows could lead to cavitation. Before installation of the replacement BG00849011 pump, it is important that one inspects the hydraulic oil, filters, suction lines, hoses, fittings and associated valves.
