Air Seal System for Slurries in Centrifugal Pumps

Designed for centrifugal pumps, the air seal system for slurries is a complete seal system. With two shaft-supporting bushings and a lantern ring, the SAS-P is a noncontact tandem seal that uses air to seal and water to flush and clean the stuffing box/seal chamber. The seal is impervious to these traditional system conditions that are considered pump and seal killers:

• Pipe strain
• Misalignment
• Off-BEP operation
• Cavitation

The new air seal system for slurries was also honored at the end of 2020 as a Processing magazine Breakthrough Product of the year.
