How a Vacuum Dehydrator Prevented Bearing Failure and Unplanned Outages

Posted by Jim Harlan on Tue, May. 16, 2017

Saves >$15,000,000 by removing water and particulate from common reservoir lube oil.

The Application

In boiler water feed pump applications, water often finds its way into the oil lubricating the pump’s bearings. This was the scenario at a paper manufacturing facility that turned to Hy-Pro for help.

The Problem

In this application, the boiler water feed pump bearing lube system was combined with the facility’s steam turbine lube oil system. The water and the particulate contamination it was bringing with it were decreasing the fluid’s ability to lubricate the bearings and causing premature wear on the bearings.

The facility was attempting to remove free water with water absorbing filters (changed weekly) but the rate of ingression was too high for the filters to be as effective as needed. And since absorbents only remove free water, the filter elements were unable to address the dissolved and emulsified water present in the oil. If the situation were to continue much longer, a premature replacement of the steam turbine and boiler feed pump bearings would be necessary outside of the scheduled maintenance periods. While possible, this solution would cost millions of dollars without addressing the root of the problem.

Selecting the right filter can improve the reliability of a system and eliminate failure. With so many options available, we understand how difficult it can be to choose just the right one. Let’s take a look at some of the hydraulic and lubrication filter types and where/how they are predominantly used to help you make the best choice for your filtration needs.
