A very important criterion for high-quality cast products is a turbulence-free and gas-free flow of the liquid melt that is as even as possible during the casting process. This can only be inade- quately achieved with mechanically operated means alone. An electromagnetically regulated solution in form of a high-delivery pump would be ideal for this procedure; this pump is able to deliver a large volume of liquid melt with a constantly adjustable performance and very high reliability.

The electromagnetic pumps for liquid metal are based on the principle of a linear motor.
This type of electromagnetic pump results in almost laminar motion of the molten liquid in the pump tube.

Advantages of electromagnetic pumps:

• no mechanical wear
• no moving parts, low maintenance
• usable at high temperatures
• laminar flow

Two pump systems are manufactured and marketed by Carli Precimeter GmbH.
