RM-TS: The First Magnetically Coupled Centrifugal Pump Without A Sleeve 


Continuous Run Dry Capability: 

Conventional magnetically coupled pumps are not designed for dry run situations.  Renner presents a totally new type of magnetically coupled centrifugal pump that works without any sleeve bearing.  This is the first time this type of bearing is used with magnetically coupled centrifugal pumps.  The coefficient of friction for this new type of bearing is so low only minimal heat is generated.  The bearing does not require any cooling or liquid lubrication.

The below video shows one of these pumps running completely dry for 10+ minutes. You don’t need to watch the whole thing. It just proves the point.
