The LAARS LAARS-A2123420 is a wet end pump bearing assembly designed as a direct replacement component for hydronic heating and hot water system circulation pumps. This assembly encompasses the bearing housing and wet end components that support the pump impeller shaft, maintaining proper alignment and reducing friction during operation. It is typically installed by licensed plumbers or HVAC technicians servicing boiler and water heater systems where pump wear or bearing failure has caused reduced flow, noise, or leakage.
This wet end pump bearing assembly is suited for residential and light commercial hydronic heating applications, including boiler-fed radiant and baseboard heating systems, as well as domestic hot water recirculation configurations. The raw title references Bradford White, indicating cross-brand applicability across LAARS and Bradford White heating product lines where this pump configuration is used. Installers replacing a failed pump bearing will find this assembly restores proper circulation performance without requiring full pump replacement.
Listed as compatible with LAARS and Bradford White heating systems where this pump bearing assembly configuration applies. Verify the existing pump model and assembly configuration before ordering to confirm fitment.
Installation should be performed by a licensed plumber or qualified HVAC technician. Before servicing, shut off system power and isolate the pump from the hydronic loop by closing service valves on both the supply and return sides, then drain any residual pressure from the line. Allow the system to cool to a safe handling temperature before disassembly. Follow local plumbing codes and manufacturer service documentation when reinstalling and recommissioning the system.
