Bell & Gossett 102223 LD3 BI Pump Cast Iron Body 1/4 HP

Description

Keep secondary hydronic water moving with Bell & Gossett 102223 LD3 BI, a 1/4 HP Series LD-3 in-line circulator with a cast-iron body and bronze impeller. The pump suits boiler branches and secondary loops where the system calls for a bronze-fitted rotating component and a flexible spring coupler. Its application also points to systems needing enhanced corrosion resistance. Confirm the electrical data, connection size, pump dimensions, and mounting orientation before replacing an existing circulator.

The three-piece in-line design uses a flexible spring coupler to transfer motor rotation to the bronze impeller. A Buna-N, carbon, and ceramic seal arrangement manages fluid around the shaft during operation. The supplied specifications do not state motor phase, voltage, flow, head, pressure, dimensions, or weight, so compare the existing nameplate and system curve before installation. Make sure the piping is properly supported and purge all trapped air before startup.

Key Features & Benefits

• 1/4 HP Motor: Supports compact secondary-loop circulation and smaller commercial hydronic applications.
• Cast-Iron Body: Provides a defined casing material for compatible boiler and HVAC systems.
• Bronze Impeller: Adds a corrosion-conscious rotating component for specified secondary-loop service.
• Three-Piece In-Line Design: Gives technicians a familiar layout for inspection and component service.

• Build: Cast iron, bronze, flexible spring coupling, and Buna-N/carbon/ceramic sealing provide identified construction details.
• Value: The three-piece arrangement gives service teams a practical layout for inspection and replacement planning.
• Audience: Suited to boiler technicians, HVAC contractors, commercial maintenance teams, and hydronic service companies.

Applications & Use Cases

Use Bell & Gossett 102223 LD3 BI in secondary hydronic loops, boiler branches, and commercial heating circuits where the bronze-fitted construction matches the system fluid. The supplied specifications do not list dimensions, weight, port size, or port-to-port reach, so confirm connection geometry, valve clearance, motor access, and support requirements before ordering.

Warranty & Support

• Warranty Terms Require Confirmation: Verify duration, coverage, exclusions, registration, and authorized service requirements with the seller before purchase.
• Match SKU 102223 and Series LD-3 Bronze Fitted details against the existing pump nameplate.

Fill and purge the loop, inspect the seal area for leakage, check the flexible coupler, and confirm the motor nameplate before wiring. Monitor vibration, noise, and temperature during startup, then verify operation against the approved system curve.
