Paper mills across the U.S., like Georgia Pacific in Crossett, Arkansas, have bearing contamination issues on their Warman AH slurry pumps. The default labyrinth type isolators allow dirt and water to reach the bearing oil decreasing the MTBR of the pump. This leads to customer concerns about frequent rebuilds. The solution was to replace the default isolators with Isomag’s magnetic face seals. Isomag bearing isolators create a positive, liquid-tight seal, eliminating ingress of slurry and water, and keeping the bearing lubrication pristine in these harsh environments.
