Tesco Engineering in Saudi Arabia, was in need of a different bearing isolator on their Flowserve 12HED 31DS API 610 radial split pump. The HED family of two-stage, radially split pumps is particularly well suited for high-temperature process applications, such as those found in hydrocarbon processing and power generation. Their customer needed to eliminate the stay mist issues they were having with labyrinth isolators that would escape through the leak path. Stray mist creates an oil slick covering surrounding the equipment and walkways, causing unsightly housekeeping and safety issues on slippery walkways. Oil mist bearing lubrication systems are used extensively throughout this refinery, and this was a growing pain point for the maintenance team.
A representative from Tesco Engineering introduced the refinery to Isomag bearing isolators as the perfect solution to their growing problem. Isomag bearing isolators eliminate stray oil mist because they are a positive seal. In addition to providing superior sealing and protection functionality the Isomag bearing isolators offer:
A high level of MTBR – projected operating life of 100,000 hours at 12,000 sfm (60 mps)
Low operating temperature – does not increase the operating temperature of the bearings
Easy installation and removal – O-ring fit on the OD of the Isomag bearing isolator makes it easy to install and if necessary remove and reinstall.
Since the installation the customer has reported that the stray oil mist issue has been alleviated and they pumps in the unit have cooler bearing housings.
A quick reminder; Isomag bearing isolators can be custom made to fit your machine. Contact our customer service team and we will help you find the ideal solution for your needs.
