Product handling applications, like mixers, blenders, agitators and rotary feed valves, often suffer from product loss and contamination due to ineffective sealing on the shaft. Ineffective shaft sealing leads to higher production costs, increased maintenance, environmental concerns and unsafe working conditions.
Traditional shaft sealing methods use contact against the shaft to seal the vessel from product loss and contamination. Over time, the sealing interface wears at the point of contact, and the seal becomes ineffective and needs replacement. The short and unpredictable service life of contact seals makes them inadequate methods of reliably sealing these applications.
A non-contacting shaft sealing solution, like the Inpro/Seal Air Mizer, offers permanent sealing on product handling applications.
The Air Mizer directs small amounts of air through a precision clearance between the throttle and the shaft, pressurising the clearance to seal against both product leakage and contamination. This non-contacting and non-wearing technology is maintenance free and designed to last the lifetime of the equipment. Its unique custom engineered design fully articulates to accommodate radial and angular shaft movement and shaft run-out.
