FILLING PUMP ASSEMBLY

550 051 78 FILLING PUMP Functioning as the heart of the drifter's lubrication system, this pump assembly circulates oil or grease under pressure to all the critical internal components. It is typically mounted on or near the feed beam, supplying lubricant through hoses directly to the rock drill. Its primary job is to create a protective film between high-friction surfaces, such as the main impact piston and the rotation gears.

A steady and correct flow of lubricant is essential for both performance and reliability. Without it, the drifter would quickly overheat, lose impact power, and suffer catastrophic internal damage. A properly working pump assembly directly contributes to longer service intervals for the rock drill and more consistent drilling penetration rates. It's a small component that protects a very large investment.

Common signs of a failing pump include low-pressure warnings, visible leaks from the pump body, or the drifter running noticeably hotter than usual. When replacing the unit, ensure all lubrication lines are clean and correctly connected. It's also good practice to prime the new pump before starting the rig to avoid running the system dry.
