Fusion device for melting solid material at ambient temperature, has pump arrangement that is connected with melting device for conveying liquefied material from melting device to application area

摘要

The fusion device has an upper container (1) for storing the solid material. A melting device (2) is arranged below the upper container to liquefy the solid material. A pump arrangement (3) is connected with melting device for conveying liquefied material from melting device to an application area (4). The pump arrangement is composed of two bellows pumps (18) which are driven by motors (19) in opposite directions.
