ABSTRACT:
A high pressure sealing assembly for a device having a rotatable shaft. The assembly includes a stationary seal member associated with the device which has an opening generally conforming to the rotatable shaft, a rotatable seal member adapted to be mounted on the rotatable shaft to engage and cooperate with the stationary seal member, and a rotatable seal collar adapted to be mounted on the rotatable shaft to engage and cooperate with the rotatable seal member. With this arrangement, the rotatable seal collar cooperates with the rotatable shaft to maintain the rotatable seal member in engagement with the stationary seal member.
