Complete tightness during the operation of the centrifugal pump is ensured by pumps with a magnetic coupling.In centrifugal pumps with a magnetic drive of the KM series, the motor shaft and the pump shaft are not connected to each other in any way, which means there is no need to make a hole in the pump casing for the shaft to exit. Torque is transmitted using magnets, one of which is attached to the pump shaft and the other to the motor shaft.
