Circulation pump
3.1. Features
The Eco Runner series of magnetically coupled centrifugal pumps are very quiet in operation.
They have fully encapsulated synchronous motors and can be operated completely safely either
submerged or out of water.
The polished ceramic shaft and bearing is practically wear-resistant, ensuring a long operating life.
An integrated thermal overheat protection device prevents damage to the windings should the
impeller rotation be impeded.
The pumps can easily be taken apart for cleaning. The direction of the rotation is controlled
electronically. This enables a very efficient operation.
All materials are salt water resistant.
