The John Crane product line specific to pulp and paper includes the SmartFlow intelligent seal support system, a revolutionary control system that reduces the amount of water used to lubricate seal faces. By limiting water consumption, pulp and paper processing companies not only save on their water bills, they can also cut any costs associated with filtration and treatment processes — resulting in significant cost savings overall. We also offer modular seals — such as our 5600 Series — that are standardized for use across the entire paper mill, and split seals (37FS) that allow for easy replacement without having to dismantle large equipment such as pulpers, agitators and fan pumps.
