Abstract:
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.
