Description
The 72HF is a single coil unbalanced seal: simple in design, reliable, and rugged enough for the most difficult duties. V packing serves as the secondary seal.
Notches in the drive give the torque the seal needs, so it runs the same in either direction of rotation.
Generally used in refineries, fertiliser plants, nuclear plants and petroleum pipelines.
