The Tuthill 7000 PD Plus series blowers are heavy duty industrial blowers designed for high performance applications in vertical or horizontal positions and airflow. Our customer, Shintech, utilized this Tuthill Blower in closed loop pneumatic conveying. The Tuthill 7000 has 5 bearings in two flooded oil sumps. The lip seals installed at the factory simply cannot be run for a long time, and Shintech was in the market for a positive seal that will hold the oil in the bearing housing.
Shintech found Isomag bearing isolators which complied with the positive seal requirement, but provided them with a seal that possessed a long life cycle. The seal has been running since 2015 and is still going today, with no leaks, while protecting the spherical bearings.
