Air Mizer CEMA shaft seal - 3 sizes

New Shaft Seal from Inpro/Seal Eliminates Product Loss on CEMA Screw Conveyors

Inpro/Seal® is excited to announce the latest AM Solutions™ design, the AM CEMA shaft seal, developed specifically for CEMA (Conveyor Equipment Manufacturers Association) Screw Conveyors.

Invented by Inpro/Seal in 2005, AM (Air Mizer®) Solutions are complete shaft seals that permanently protect against product loss and contamination on industrial processing equipment. By utilizing a positive air- or inert gas- purge, Inpro/Seal AM Solutions shaft seals provide a non-contacting and non-wearing seal, lasting the lifetime of your equipment.

Shaft movement and misalignment are common on screw conveyors. Traditional seals rely on dynamic contact to create a seal. Shaft movement creates frictional contact, causing the seal to wear or groove the shaft, leading to seal failure. Seal failure brings higher production costs, increased maintenance, environmental concerns and even unsafe working conditions.

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 unique, 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.

The Inpro/Seal AM CEMA shaft seal is designed specifically to fit standard CEMA Screw Conveyor dimensions. To determine the correct AM CEMA shaft seal for your CEMA Screw Conveyor, visit
