Abstract
A seal chamber housing is provided for equipment with rotating shafts and includes a stepped conical bore open at the pumping mechanism end. The bore defines a seal chamber affording greater volume about the associated mechanical seals and a tapered bushing is optionally sealingly seated in the large diameter end of the stepped conical bore for excluding pump fluid from the seal chamber and/or preventing loss of seal flush liquid from within the seal chamber. In addition, the seal chamber includes upper and lower vent and drain ports primarily for use when the optional bushing is in place and said chamber also includes flushing fluid ports, a closed temperature-controlling external fluid channel and external air cooling features, all of which coact in various operating environments to provide longer and more efficient mechanical seal life.
