Settima offers for all pumps model (please contact Settima for more info on the pump model chosen) the magnetic coupling option to replace the standard seals.

The magnetic coupling is a permanent magnetic synchronous coupling that transmits torque through magnetic forces between the internal and external rotor. Using the magnetic coupling, as sealing element, the drive and the driven side are hermetically separated. For critical media works as a reliable seal and prevents serious leaking.

The magnetic coupling is the containment shroud that is fixed to the driven sided power unit and separates internal and external rotor from each other. The vibration torque transmission are very low, due to the absence of mechanical connection with completely leak-proof separation of product and atmosphere.

The magnetic coupling therefore is used to ensure no media leaking or when pumps are used hazardous areas such as explosive areas.

Zero pump maintenance: there is no more the requirement to periodically check /change the sealing. The maintenance cost drop down drastically

NO leakage: there are no rotary parts sealed, but only static sealing

Component protection: the magnetic coupling also protect the motor from damages. If the pump require a torque (power) bigger that the maximum allowed, the magnetic coupling automatically detach the power transmission.
