New Technology of Mechanical Seal Application of Magnetic Drive Seal Pump
　2017-01-13　　
Magnetic drive sealed pump is a new type of mechanical seal technology with no shaft seal structure and no leakage. It separates the pump shaft from the power shaft through an isolating sleeve and is not directly connected. The permanent magnets on the pump shaft and the power shaft transmit power and torque. The coupling is also omitted, so that the dynamic seal becomes a wide and static seal. This is safer for transporting special media, especially toxic media. This technology has been successfully applied to 55[cut propane pumps in some petrochemical companies. But there are also problems, that is, magnets are expensive, and the lubrication of the bearings in the pump is related to the lubricity and corrosiveness of the medium.　　238.html,
