Abstract

Displacement pumps belong to a subcategory of transfer pumps. The general characteristic of these pumps is continuous displacement of gases from a vacuum system via the pump interior to discharge them into the atmosphere or to a higher-pressure zone, from where they are removed by another pump. Most displacement pumps work against atmospheric pressure.
