Diaphragm pumps are categorized under the most common types of industrial pumps. It makes use of the so-called positive displacement method in order to move a liquid from one location to another. Such devices work through the presence of a chamber, diaphragm, suction and discharge check valves. Pistons are also joined to the diaphragm in order to push hydraulic oil as the diaphragm does its work.
Some of the most common diaphragm pump materials are ethylene propylene, plastic, elastomer, rubber and polytetrafluoroelthylene. These materials are used in order to make the pump resistant to chemicals, weathering and sunlight. Housing the diaphragms are other materials such as aluminum, cast iron, plastic, stainless steel, brass and bronze. Rugged versions of housing withstand higher temperatures.
