Gearbox & Hydraulic Oil Sump Flushing Machine

Gearboxes and Hydraulic power packs periodically need a thorough flushing rather than a simple drain and fill. Several signs point to this requirement, such as overheating of the sump, total liquid or solid contamination. Sludge, rust, moisture, wear metals, gel or other viscous residue that is present at the beginning of the drain should confirm to the technician that a flush is in order. A thorough flush is also useful for removing contaminants from equipment sumps prior to commissioning.

Flushing is a clean flushing fluid circulation process with adequate filtration housings designed to remove water, chemical contaminants, and particulate matter resulting from manufacturing, regular ingression, internal generation or component wear.

For in-service machinery after an oil change due to heavy fluid contamination, component failure, extremely degraded lubricant (oxidation), or if a system flushing has not been performed in the past few years.

For gearboxes and bearing housings that are not fitted with filtration, flushing is required to remove contamination and sediment before every fill of new oil. Water, rust, excessive wear debris, sludge, varnish or lacquer, and hard-to-open drain ports suggest system contamination and indicate the need for a thorough flush. Even 5% percent of the old contaminated or depleted lubricant may be enough to use up most of the additives of the new oil, hence flushing is an important proactive procedure in every plant.
