Separation Seal (Non-contacting Technology)
The Type 93FR is a non-contacting carbon bushing designed to protect dry gas seals from bearing oil ingress. Segments are specifically designed to prevent oil migration. Separation gas (normally nitrogen or air) is injected between the two segmented bushings, effectively creating a pressure barrier between the bearing and dry gas seal cavity. Advanced materials and design eliminate wear under normal running, promoting long service life.
