Bell & Gossett Series 2-1/2" 1/4 HP 115V 110 GPM Oil Lubricated Three Piece Cast Iron Circulator Pump with Non Ferrous Impeller - 102218

Power Bell & Gossett 102218 2-1/2" 1/4 HP Oil-Lubricated Three-Piece Cast-Iron Circulator

Move hot water reliably in closed-loop hydronic systems with the Bell & Gossett 102218 (Series 2-1/2, Model 2-1/2 IB). This oil-lubricated, three-piece inline booster is built for long service with quiet, resilient motor mounts and sleeve bearings. The 115 V, 1/4 HP motor is designed for 1725 RPM operation, and a pair of 2-1/2" flanges is included to streamline change-outs. Rated for up to 125 psi and 225 °F (standard seal), it’s a dependable upgrade for residential and light commercial hydronic circulation.

Everyday Performance You Can Count On

Built for hydronic heating and cooling loops, the 102218 circulates reliably across long duty cycles. Oil-lubricated sleeve bearings, close impeller/volute tolerances, and a resilient motor mount help maintain efficiency and smooth operation over years of use.

Three-Piece, Serviceable Design

The classic B&G layout—motor, bearing assembly, and volute—means you can service the bearing/shaft/seal assembly without disturbing piping. That reduces downtime and keeps total maintenance cost low across the pump’s life.

Quiet, Oil-Lubricated Operation

Bronze sleeve bearings circulate oil over bearing surfaces for low noise and long wear. A spring-type flexible coupler further damps vibration for quiet performance in occupied spaces.

Installer-Friendly Connections

Standard 2-1/2" flanged ends drop into existing inline layouts, and the included flange set speeds replacement. The 115 V, single-phase ODP motor simplifies power and start-up.

Sized Right For Retrofits

With an overall length around 17-1/4" and low profile about 10" high, the Series 2-1/2 fits common mechanical-room clearances. Verify width and service access against your submittal before setting the flanges.

Materials To Match Your System

The 102218 “IB” ships with a cast-iron body and steel impeller for closed-loop heating. For non-ferrous requirements or potable water, choose the sister “BI” bronze-impeller model (102219) or use the bronze impeller service part.

Built For Closed-Loop Hydronics

Designed for hot-water circulation in sealed systems, the pump is rated to 125 psi and to 225 °F on a standard seal—with higher-temperature special-seal options when needed.
