Magnetic coupling is widely used in various fields such as magnetic drive of sealing vacuum of metering pump of polyurethane foamer, magnetic drive of pneumatic ball valve, magnetic drive of stirring reactor, etc. to prevent leakage of raw gas. Magnetic coupling is mostly used in high vacuum, high cleanliness, poisonous, corrosive, or harsh environment to transfer power from the driving shaft to the driven shaft. Because of the use of isolation seal sleeve, dynamic seal into static seal, zero leakage can be achieved.
