ABSTRACT:
A process and apparatus for degassing high-boiling liquids, especially polymer melts and solutions, to remove low-boiling liquids and gases as impurities by feeding the polymer melt or similar high-boiling liquid under expansion into the feed chamber of a gear wheel pump to flow downwardly and only partially fill this feed chamber, preferably so as to form a thin layer or pool of the melt atop the upper crown surfaces of the gear wheels. The impurities are withdrawn separately through a suction outlet and the liquid level of the melt is preset and maintained by suitable regulating apparatus adapted to control the speed of the gear wheels and/or the speed at which melt is delivered into the pump feed chamber.
