How to reduce wear on a diaphram

Air-operated diaphragm pumps are common industrial pumps that use positive displacement to move liquids. These devices, used in a variety of industries and applications, typically include a single diaphragm and chamber, as well as suction and discharge check valves to prevent backflow. Air-operated diaphragm pumps are highly reliable because they do not include internal parts that rub against each other. In fact, prolonged diaphragm life may be possible if the diaphragm pump is run dry to prime.

Typically, wear on the diaphragm or flap is due to the corrosive properties of media fluids or gases and/or excessive air supply pressures. Air-operated diaphragm pumps can handle a range of media that includes abrasive materials, acids, chemicals, concrete or grout, coolants, combustible or corrosive materials, effluents, groundwater, and gasoline or diesel fuel. Some can even handle hazardous materials, highly viscous fluids, liquids with solids, or liquids with oil.

The E6 ¼-inch air-operated double-diaphragm pump, for example, features a leak-free design that reduces downtime, ensuring continuous, reliable pump performance. It is the latest addition to Versa-Matic's line of plastic pumps, and features dual-threaded manifolds; optional manifold configurations; an integrated muffler; and it’s self-priming.
