MODIFIED ROTATING SURFACE FOR MECHANICAL SEALS IN CENTRIFUGAL PUMPS.

摘要

The present invention consists in an improved single-piece Modified Rotating Surface made of phenolic resin by an injection molding method, which advantageously substitutes the rotating surfaces of two pieces currently used in mechanical seals of the D and F type for sanitary centrifugal pumps of the C and SP Purity-Waukesha type.
