Diaphragm pumps are positive displacement pumps which are used to pump fluids with the help of reciprocating motion of the diaphragm. Diaphragm pumps mainly consist of a reciprocating diaphragm made up of rubber or other polymeric materials and check valves which control the incoming and outgoing fluid. Moreover, selection of a suitable diaphragm material according to the application is the most important factor for longer life of diaphragm pumps.
For better service life of diaphragm pumps structured diaphragms are used in many applications. Sometimes, for higher capacity, double diaphragm pumps are used in place of single diaphragm pumps. The energy required for the reciprocating motion of diaphragm can be derived from a mechanical drive or a hydraulic drive. Furthermore, the output fluid volume can be controlled in two ways, either by changing the length of the diaphragm stroke or by varying the speed of diaphragm stroke. Diaphragm pumps are employed for high to medium flow rates at high pressures. Because of their ability to handle different types of fluids, diaphragm pumps are used in various industries like construction industry and chemical industry.

Diaphragm Pumps Market: Market Dynamics
Technological advancements have led to the development of many compact diaphragm pumps which are relatively simpler in design. This has resulted in an increase in adoption of diaphragm pumps in many industries, thus resulting in steady growth of diaphragm pumps market during the forecast period. Moreover, characteristics of diaphragm pumps like variable flow control, relatively lower maintenance cost and relatively lower downtime tends to render diaphragm pumps ideal for a gamut of applications. In many offshore drilling applications diaphragm pumps are well suited to transport toxic and corrosive fluids without leakage, this tend to promote growth of diaphragm pumps market during the forecast period. Introduction of air operated double diaphragm pumps for transport of liquids containing large solids without utilization of electricity is expected to drive the growth of diaphragm pumps market.
Air operated double diaphragm pumps sometimes tend to result in problem of water hammering, this tends to limits the use of diaphragm pumps, thus acting as an impediment to growth of diaphragm pumps market. Moreover, the operating cost of air operated double diaphragm pump is relatively higher as compared to that of conventional electric drive pumps, this is another factor that is expected to have an adverse impact on growth of diaphragm pumps market. Efficiency of larger diaphragm pumps is reported to be relatively lower. Furthermore, the problem of pulsation is also associated with diaphragm pumps, causing vibration in diaphragm pumps, thus limiting their application in certain areas.
Developments in double diaphragm pumps have led to introduction of high speed and high pressure Air Operated Double Diaphragm (AODD) pumps in the market. These AODD pumps find applications in construction and chemical industries.
