Confirm the configuration before ordering Bell & Gossett 622S Series 60 centrifugal pump for commercial HVAC and primary boiler circulation. The supplied data identifies a 3/4 HP single-phase pump with 115 or 208–230-volt service and a 3-inch by 3-inch by 5-1/4-inch arrangement. Official Bell & Gossett data associates SKU 172757LF/622S with a 1-1/2-inch by 1-1/2-inch by 7-inch pump and 5.5-inch impeller.

This dimensional conflict affects flange selection, hydraulic performance, and replacement fit. The official listing identifies SKU 172757LF as model 622S, 3/4 HP, single-phase, with a different pump size and impeller diameter. Verify the nameplate, SKU, flange pattern, impeller trim, voltage, and performance curve before purchase. Do not combine the conflicting specifications.
