Bell & Gossett Series 2-1/2 Cast Iron Inline Booster Pump, 1/4 HP - 102218

The Bell & Gossett 102218 (Series 2-1/2, Model 2-1/2 IB) is an oil-lubricated, three-piece inline booster for closed-loop hydronic heating and cooling. A 115V, 1/4 HP motor turning at 1725 RPM drives water through a cast iron volute with 2-1/2 in. flanged ends.

The three-piece layout separates motor, bearing assembly and volute, so the bearing, shaft and seal can be serviced without breaking the piping. Bronze sleeve bearings run in circulating oil and a spring-type flexible coupler damps vibration, which keeps the pump quiet in occupied buildings. It is rated for 125 psi working pressure and 225 F with the standard seal, or 250 F with special seals. The motor is single-phase ODP, and two 2-1/2 in. flanges come with the pump to simplify change-outs in residential and light commercial mechanical rooms.
