The Worthington / Flowserve 3 FRBH is an extremely popular heavy duty paper stock & process pump found in paper mills across the United States. This horizontal pump is most commonly found in cellulose fiber slurries, evaporators, concentrators, waste stock & black liquor. These pumps have proven to be robust and reliable in paper mills around the country.
Usually the Worthington / Flowserve 3 FRBH line is equipped with a lip seal or labyrinth, however since most of these pumps are stationed in wet and steamy areas, the bearing housings has issues with water vapor ingress. West Rock Paper in Demopolis, Alabama, was looking for a better and more long term solution. Isomag magnetic bearing isolators are a positive seal and will hold oil in, and keep the external contaminates out of the bearing housing. Our customer West Rock Paper found Isomag bearing seals to be their best solution for maintaining their maintenance lifetime goals.
