The magnetic coupling transmits the power of a motor to the drive shaft without direct contact.
The motor drives the outer rotor. Due to the repulsive or attracting force of the magnets, the inner rotor rotates synchronously with the outer rotor without the two directly touching. Thus the inner rotor drives the drive shaft.
The containment can seals the inner rotor and the medium inside the pump and prevents toxic or corrosive substances from escaping from the pump.
