Atlas Copco 5112287802 / R902431981 Hydraulic Pump

The Atlas Copco 5112287802 / R902431981 Hydraulic Pump is a compact variable axial piston pump suitable for installation in compatible Atlas Copco and Epiroc drills. It produces hydraulic oil flow needed by the machine for controlled movement and pressure and reliable response. The pump is ideal for use in mining, tunnelling, and drilling works where the hydraulic parts should work consistently for long periods of time.

The pump has a variable displacement A10VO28 open-circuit hydraulic system and operates on the swash plate method. Thus, it is able to vary the displacement depending on the hydraulic demand of the machine. Instead of continuously giving the maximum flow of oil, the pump produces the oil based on the demand. It increases the hydraulic efficiency, reduces the generation of excessive heat and helps to ensure smooth machine operation.

The part numbers 5112287802 and R902431981 identify the hydraulic pump configuration described above. The compact 28 cm³ displacement class is the appropriate balance between size and hydraulic capacity of the pump. The sturdy cast housing protects the pistons inside, while the control system provides pressure and flow regulation in different load conditions. These characteristics allow using it in compatible Boomer, Simba and other drill rigs hydraulic systems.

We also provide services of hydraulic pump testing, inspection, repair, maintenance, internal parts replacement and performance analysis. Common issues we address include low flow rate, low pressure, unusual noise, overheating, internal wear and hydraulic fluid leakage. Regular maintenance improves pump efficiency and stops further damage to the connected hydraulic parts.

It is very important to have clean hydraulic oil, effective filters and unobstructed suction line to ensure efficient working of the pump. It is also necessary to ensure that there is no contamination of the hydraulic system during installation of the new pump due to the existing problem.
