If the water temperature on water-cooled gear reducers is too cold, water could condense and get into the oil. If there is water on the floor, on the cooling water lines going into the gear reducer, or if the gear reducer is sweating, water may have gotten into the oil.

If this occurs, increase the water temperature until the water lines quit sweating, then test for water in the oil. If this issue isn't corrected quickly, it could be catastrophic. (Hack Hensley, predictive maintenance, Mitsubishi Polyester Film)

From "Operator's Guide to Centrifugal Pumps"

An oil's lubricating performance is greatly degraded by contamination due to ingress of atmospheric water and dirt, and oxidation, a chemical reaction between oxygen and oil at high temperatures. Operators must be aware of these two pump killers. Special bearing housing seals can be installed that will greatly reduce external sources of contamination. As for oxidation, synthetic oils can be employed to handle high operating temperatures.

Question: What oil conditions are monitored when doing a condition-based oil change?

Get the answer.

Many companies try to capture leaking fluid - sometimes in elaborate guttering systems - to reclaim and recondition before returning the oil to service, rather than fixing the problem. But is this really a sound strategy?

Learn why you may, or may not want to catch and reclaim leaking oil in this Machinery Lubrication article.
