AXIAL PISTON PUMP

886 853 09 AXIAL PISTON PUMP Located in the main power pack, this axial piston pump converts the engine's rotational power into hydraulic energy. It creates the high-pressure flow required to operate all the machine's functions, including the drifter's percussion and rotation, the feed system, and the positioning boom. The pump's output directly determines the overall speed and power of the drilling cycle.

A healthy pump ensures consistent and reliable performance from your equipment. If the pump starts to wear, you'll notice a drop in hydraulic pressure, leading to sluggish boom movements and reduced impact energy at the rock drill. Internal wear can also shed metal particles into the hydraulic oil, which can damage other sensitive components like control valves and motors down the line.

Listen for unusual whining or grinding sounds from the power pack, as this often indicates pump wear. A gradual loss of speed in hydraulic functions is another key symptom. When installing a new pump, it is crucial to also change the hydraulic filters and check the oil for contamination to prevent premature failure of the replacement unit.
