Description
The Xylem-Bell & Gossett P11150 Washer is a small mechanical fastening component used in pump assemblies to maintain proper alignment and secure internal rotating parts during operation. It acts as an impeller lock washer that helps hold vital pump elements in place, preventing loosening caused by vibration and continuous mechanical load within HVAC systems such as hydronic circulation pumps, boiler water systems, chilled water loops, and closed-loop heating circuits. The washer is placed within the pump shaft assembly where precise mechanical stability is required for consistent operation. Its retaining action improves component stability, reduces internal damage, and assures proper fluid circulation.
