• Long bronze sleeve bearings maintain exact shaft alignment and provide constant circulation of oil over bearing surfaces
• Noise dampening coupler for quiet operation
• Precision ground oversized pump shaft provides large bearing surfaces with hardened integral thrust collar to minimize end-thrust and ensure long seal and bearing life
• B&G mechanical seal designed to withstand wide range of water temperatures, pressures, additives and dissolved solids common in hydronic systems
• Plastic impeller
