Domtar Paper in Bennettsville, South Carolina needed a better solution for their Sunds DKB 80 pump. This Sunds pump is a pump through pressure knotter used to eliminate knots and un-cooked chips in the pulp. Designed for hot stock screening, it offers a totally closed system from blow tank to drum washers or from diffusion washer to fine screening system. The problem they were having was both egress of bearing lubrication and ingress of contamination into the bearing housing.
When the mill specified Isomag bearing isolators for their Sunds pump in 2008, they were very happy with their decision. The Sunds pump has been running leak free and contamination free since then.
Isomag bearing isolators are a positive seal that wont damage the shafts of your pump, and work in horizontal or vertical up or down positions. Isomag bearing isolators also work perfectly in grease lubrication environments.
