Articulating shaft seal to cope with run out
I npro/Seal has introduced a new ver- sion of the Articulating Air Mizer-PS seal that is designed specifically for powder and bulk applications where there may be severe radial run-out and axial shaft movement.
The seal is a development of the existing Air Mizer-PS that is intended to use minimal amounts of air pressure to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored. The new seal is the result of direct customer requests to add the ability to handle the extreme shaft run-out and deflection that is common in this sort of application with the benefits of a non-contacting seal.
The seal uses an air barrier directly on the shaft, allowing for unlimited axial movement without placing any stress or strain on the product. Without any rotating parts, the shaft floats in the seal attaining zero contact and zero wear.
The seals are custom-engineered to suit individual applications and no modifications to the equipment are necessary as it conforms to existing clearances, boltholes and patterns for bearings and/or stuffing boxes. Split designs allow for installation directly on the shaft without the removal of couplings and end plates.
