GEAR PUMP

550 490 62 HYDRAULIC PUMP, EXTERNAL GEAR A GEAR PUMP is a fundamental component in any hydraulic system, responsible for converting mechanical energy into hydraulic energy by creating fluid flow. In a rock drilling rig, this pump typically draws hydraulic oil from the tank and delivers it under pressure to the main distribution manifold. From there, the pressurized oil powers the drifter's percussion and rotation, controls the feed system, and enables precise boom movements. Without a functioning pump, the entire hydraulic circuit comes to a halt, stopping all drilling operations.

The consistent performance of the hydraulic pump directly impacts the efficiency and safety of underground drilling. If the pump struggles to maintain adequate pressure or flow, you'll notice a significant drop in drilling penetration rate, slower boom articulation, and reduced impact energy from the drifter. This can lead to extended drilling cycles and increased operational costs. Maintaining proper hydraulic fluid levels and cleanliness is crucial, as contaminated oil is a leading cause of premature pump wear, affecting both reliability and the lifespan of other hydraulic components.

Common signs of a failing GEAR PUMP include unusual whining or grinding noises from the pump itself, overheating hydraulic oil, or a noticeable decrease in the speed and power of hydraulic functions. Visible leaks around the pump body or shaft seal also indicate a problem. When these symptoms appear, it's often time for a replacement to prevent further damage to the hydraulic system. Regular checks of hydraulic fluid quality and timely filter changes can extend the life of your pump and the entire hydraulic circuit.
