Air Operated Double Diaphragm Pumps

Design Features

Air operated diaphragm pumps are reciprocating pumps where the working elements are flexible diaphragms. The drive is by means of compressed air acting directly upon the diaphragm. Another possibility is hydraulically drive instead of compressed air. At least two valves, one on the discharge and one on the suction side, are necessary. Several types of valves are used. The most popular valves are flap, cylindrical and ball valves.

Air-operated double diaphragm pump is a self-promised pump to work hard against huge number of Liquids and atmosphere donate driver seat to user.

It can move anything from fine chemicals (gentle, non-shearing action), to abrasive and viscous slurries (no close-fitting parts, low internal velocities), and almost any other product.
