IN MORE DETAIL

Cost-saving technology

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 Type 5600 series and heavy duty SB Series — that are standardised 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.

FREQUENTLY ASKED QUESTIONS

Common questions

What are pulp and paper sealing products?

Pulp and paper sealing products are engineered sealing solutions designed for equipment used in pulp production, paper manufacturing and related mill processes. These products help prevent leakage, control contamination and maintain reliable performance in harsh operating environments involving high temperatures, abrasive media and continuous operation.

What types of sealing solutions are used in the pulp and paper industry?

The pulp and paper industry typically uses mechanical seals, cartridge seals, split seals and support systems designed for pumps, agitators and refiners. These pulp and paper sealing products are built to withstand abrasive slurries, chemical exposure and high-demand continuous production environments while maintaining long-term reliability.

Why are sealing products important in pulp and paper manufacturing?

Sealing products are critical in pulp and paper manufacturing because they help prevent fluid leakage, reduce unplanned downtime and protect rotating equipment from wear and damage. Reliable sealing performance supports production efficiency, improves safety and helps maintain consistent output quality in mill operations.

How do I choose the right sealing solution for pulp and paper equipment?

Selecting the right sealing solution depends on factors such as equipment type, operating pressure, temperature, fluid characteristics and contamination levels. The right pulp and paper sealing products are those that balance durability, efficiency and ease of maintenance while supporting long-term operational reliability.
