The AM CEMA shaft seal (photo) has been designed specifically for Conveyor Equipment Manufacturers Association (CEMA) screw conveyors. The AM CEMA shaft seal utilizes a positive air- or inert-gas- purge to create a barrier between the shaft and seal, eliminating product leakage and process contamination. Due to its non-contacting design, the AM CEMA shaft seal has no wearing parts, requiring minimal maintenance or need for rebuild kits. To accommodate shaft movement, the AM CEMA shaft seal fully articulates to allow for radial run-out and angular misalignment simultaneously. — Inpro/Seal, Rock Island, Ill.
