Sleeve bearing, oil lubricated with replaceable resilient motor mounts
Noise dampening coupler
Flexible spring design adds to quiet operation, do not accept a substitute
Long bronze sleeve bearings maintain exact shaft alignment
Provides for constant circulation of oil over bearing surfaces
Precision ground pump shaft is oversized to provide large bearing surfaces
Hardened integral thrust collar minimizes end-thrust to ensure long seal and bearing life
The Bell & Gossett standard mechanical seal is designed to withstand the wide range of water temperatures, pressures, additives and dissolved solids common in hydronic systems
