Obstructions and/or blockades on the load side of the system happen often. For example, an unexpected event in the process by which a conveyor belt gets blocked, or the impelllor of a pump gets blocked suddenly, etc. Many different examples could be given. The consequence is that the installation can be seriously damaged. In such a situation a fixed coupling (claw, gear, pen, rubber or fluid coupling) is normally broken. It can also create very dangerous situations caused by loose components.
In case of frequent obstructions and/or blockades the contact-free magnetic coupling will not result in damage to the system. In case of flow dip the motor needs to be switched off. The magnetic coupling prevents serious damage and system downtime.
