Diaphragm pumps use flexible diaphragms and check valves to move fluid through controlled suction and discharge cycles. This operating principle makes them suitable for a broad range of fluid-transfer duties, including applications involving challenging or chemically aggressive fluids.
Depending on the selected configuration, diaphragm pumps can be supplied in different sizes, materials, port arrangements, and drive options. Air-operated and electric double-diaphragm configurations are available in industrial pump ranges, allowing the pump to be selected according to the required process conditions.
