Bell & Gossett 102228LF HD3-AB Circulating Pump Unit

Module Feature102228LF belongs to Bell & Gossett HD3 AB series inline circulator pump under Xylem group. Three-piece split pump structure,all bronze volute and impeller,3-inch flange connection,1/3HP single-phase motor,115/230V dual voltage. Spring coupling and resilient motor mounting reduce vibration and noise. Modular bearing assembly design allows on-site maintenance without removing pump volute from piping. Widely used for potable domestic hot water circulation and water pressure boosting in commercial buildings.

Working principleMotor drives bronze impeller to generate centrifugal force to circulate water inside piping. Bronze wetted parts provide corrosion resistance for clean domestic water. Flexible spring coupling isolates motor vibration from pump casing to achieve quiet continuous operation.

Onboard componentsAll bronze pump volute,bronze impeller,mechanical shaft seal,bearing cartridge assembly,single-phase TEFC motor,spring coupling,3 inch flanges,gaskets and mounting hardware.

LED indicatorsNo built-in LED indicators.

Hardware self-diagnosisVisual inspection for seal leakage,check motor winding insulation resistance,bearing noise and temperature measurement,flow and pressure test.

Programming softwareNo dedicated programming software.
