Liquid ring pumps are an ideal solution when gases are contained in the process medium. Because the pumps are self-priming when the casing is half filled with fluid, they are capable of pumping from a suction line that is partly filled with air or other gases.

Alfa Laval’s liquid ring pumps are specially developed for use in food, chemical and pharmaceutical industries, where they are often used as return pumps in Cleaning-In-Place (CIP) systems.
