The Ahlstrom APT 53-8 is single-stage stock pump and is an extremely common pump in the pulp mill process. Many mills have multiple Ahlstrom APT 53-8 pumps in service, but only have few spare units, like our customer International Paper in Mansfield, Louisiana. This means having the right choice in bearing protection is a large factor in helping these pumps reach their planned maintenance cycles so the mill doesn't feel the pain of downtime. Isomag magnetic bearing isolators are the seals chosen by the maintenance team to make sure the MTBF is long.
