Powder mixing equipment result in and extremely aggressive environment for sealing rotating shafts. Mixing equipment typical has high levels of both dynamic and static eccentricity with the seals expected to run without lubrication to prevent contamination of the powder.

To overcome these issues Race-Tec have developed our MT seal, which has been thoroughly tested and has been adopted by an OEM for powder processing. The dynamically loaded self-compensating rotary shaft seal uses an integrated PTFE liner as the only interface with the shaft. This sealing lip design reduces surface wear and running friction whilst accommodating significant radial and angular misalignment. The enclosed, compact (8 x 8mm) designs offers no areas for powder entrapment.

Race-Tec have developed special material formulations have been developed containing only approved ingredients at levels permitted under CFR 21 FDA 177-2600, capable of temperatures up to 230°C
