In the pulp and paper processing industry, efficiency and reliability are key to controlling expenses because they help reduce the amount of energy required by critical processes. John Crane maximizes both — and helps companies meet strict pollution regulations — with engineered components and seal support systems that limit emissions, tolerate high temperatures and reduce water consumption. Plus, our 200+ rapid-response facilities can also minimize unplanned downtime by providing service, repair and support worldwide.
We deliver proven mechanical seal technologies and services that improve manufacturing performance through:
- increased operational reliability
- improved equipment uptime
- fewer maintenance interventions
- reduced seal water usage
Recommended for You
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.
