Get More Out of Sulzer WPT ANSI Pumps With Isomag Bearing Isolators

May 11, 2018

The Sulzer WPT ANSI Pumps are an extremely popular pump found in paper mills across the United States. Most commonly found in the white and black liquor process as well as the digester process, these pumps have proven to be robust and reliable in paper mills.

Usually the WPT line is equipped with a labyrinth from the OEM.  Which has commonly been found to have an oil leakage issue. Many customers have tried other style labyrinths which typically fair better on the leaks. However since most of these pumps are stationed in wet and steamy areas, the bearing housings have issues with water vapor ingress. Isomag bearing isolators are a positive seal and will hold oil in, and keep the external contaminates out of the bearing housing. Many customers from International Paper, West Rock, & Domtar Paper have found Isomag bearing isolators to be their best solution for maintaining their maintenance lifetime goals.
