Isomag Bearing Isolators Protect Pearce Dredge Pumps for the Bauxite Industry

Isomag bearing isolators solve contamination issues for dredge pump applications in the bauxite/aluminum industry. Noranda Alumina, in Gramercy, Louisiana was having bearing contamination issues on their Pearce dredge pumps. The default labyrinth type isolators were allowing dirt and water to reach the bearing oil decreasing the MTBR of the pump. This lead to customer concerns about frequent rebuilds.

The solution was to replace the default isolators with Isomag’s magnetic face seals. Isomags create a positive, liquid-tight seal, eliminating ingress of mud and water, and keeping the bearing lubrication pristine in these harsh environments.
