Suncor Uses Isomag Bearing Isolators To Seal Oil Mist On Flowserve HWX Pump
Suncor Energy in Edmonton, Alberta, was in need of a different bearing isolator on their Flowserve HWX pumps. This vertical in-line API 610 OH3 pump can be found on oil rigs and refineries all around the world. Suncor Energy needed to eliminate the stray mist issues they were having with the factory installed 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 sales representative from John Crane 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 in 2012 the customer has reported that the stray oil mist issue has been alleviated and the motors in the unit have cooler bearing housings.
