AIR SEALS
SAS Air Seal
The SEPCO SAS is an engineered pneumatic sealing system designed to seal the shafts of equipment where typical contact seals, such as packing and/or mechanical face seals, prove too costly to operate and maintain.
Design Features
» Efficient design minimizes air usage while maintaining an internal sealing pressure profile
» Resilient to angular and parallel shaft movement
» Split seals are available in most designs
» A wide range of materials is available in most designs
» Requires little to no maintenance after installation

SAS-P System for Centrifugal Pumps
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
