What are the advantages of diaphragm pumps?
A. Liquid does not leak from diaphragm pumps as they do not have mechanical sliding sections at liquid-contacting parts. This makes diaphragm pumps ideal for volatile liquids, liquids that cause hazards when leakage occurs, and liquids that solidify through contact with air. Diaphragm pumps ensure feeding of liquids at constant amounts in such applications even if the pressure changes at the discharge side.
