Abstract

The invention relates to a seal system comprising a stationary assembly having an angled profile, and a rotary assembly comprising a resiliently flexible rotary elastomeric member. When in a rest position, the rotary elastomeric member contacts the angled profile of the stationary assembly to seal a gap therebetween. On rotation of the rotary elastomeric member, the gap between the assemblies is opened to allow fluid flow therethrough.
