Sleeve bearing, oil lubricated with replaceable resilient motor mount Noise dampening coupler own flexible spring design adds to quiet operation 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 mechanical seal is designed to withstand wide range of water temperatures, pressures, additives and dissolved solid common in hydronic system Centrifugal impeller prevents accumulation of air at seal faces to assure long life, close impeller/body tolerances minimize water slippage and maximize efficiency
