IMPROVED SEAL SYSTEM FOR CENTRIFUGAL PUMPS HAVING AXIALLY SPLIT CASINGS

摘要

Disclosed invention is an improved sealing system for axially split, centrifugal pumps. The improved sealing system eliminates the need for a gasket between casing halves. In the improved sealing system, a fluid tight seal is provided by an elastomeric cord positioned within a groove carried by the flange of at least one half of the axially split pump casing.
