Bell & Gossett DP0708 Propeller Stem Assembly

Bell & Gossett DP0708 Propeller Stem is an OEM replacement part for Hoffman Specialty/Bell & Gossett Series B-35 centrifugal pumps, serving as the shaft-to-propeller interface within the pump’s impeller assembly. In Bell & Gossett/Xylem parts catalogs, DP0708 is listed as the Propeller Stem for Series B-35, 3500 rpm, low-NPSH configuration and appears in the D-421P-F Domestic Pump Series B-35 parts sheet, confirming its place in the standard propeller assembly. This stem is designed to integrate with the propeller and its associated hardware—propeller, propeller set screw, stem locking pin, and diffuser—as part of the complete propeller assembly that drives the pump’s flow. As a genuine Xylem/Hoffman Specialty component, DP0708 is intended for use with compatible B-35 pump configurations and should be installed with the matching hardware per the pump’s service documentation to ensure proper alignment, reliable operation, and serviceable wear characteristics over the pump’s life. Designed as a wear part within the impeller assembly, it is commonly replaced during scheduled maintenance or rebuilds to restore original alignment and flow characteristics.
