Power Bell & Gossett 106192LF Series 100 AB 1/12 HP Lead-Free Bronze Circulator Pump

Keep domestic hot water and hydronic loops circulating quietly with the Bell & Gossett Series 100 AB (model 106192LF). This three-piece, oil-lubricated inline booster is built for easy field service—bearings, shaft, and seal are in a removable assembly—while the 115V, 1/12 HP motor delivers dependable, low-head, high-flow performance up to 33 GPM. All-bronze, lead-free construction (body and impeller) makes it a natural fit for potable-water and non-ferrous systems. It’s the classic, proven B&G design that runs quietly for years and swaps in cleanly on a flange connection.

Quiet, Reliable Circulation

Oil-lubricated sleeve bearings and a spring-type flexible coupler damp vibration for smooth, low-noise operation in occupied spaces. The non-overloading motor is designed for long life across the Series 100 pump curve.

Serviceable Three-Piece Design

Classic B&G architecture (motor, bearing assembly, volute) lets you replace the bearing/shaft/seal assembly from the front without disturbing piping—minimizing downtime and labor on future maintenance.

All-Bronze, Lead-Free Construction

The AB variant ships with a lead-free bronze body and bronze impeller for potable-water and other non-ferrous piping systems—ideal for domestic recirculation and food-service applications.

Installer-Friendly Fit

A compact 14-7/8" length and flanged inline body drop into existing Series 100 layouts. Choose the flange size that matches your piping (3/4" to 1-1/2"), and use the included bolt pack and gaskets for a clean seal.

Made For Low-Head, High-Flow Loops

With up to 33 GPM and 8 ft of head, the 106192LF is tuned for typical domestic hot-water recirculation and short hydronic loops—exactly where the Series 100 has been the industry standard for decades.

Built To Code Expectations

Series 100 circulators are UL listed and rated to 125 psi and 225 °F (standard seal), so you can specify confidently and pass inspections when installed per manufacturer guidance.
