The water & wastewater segment is expected to be the largest and fastest growing market, by end user, during the forecast period.  The water & wastewater segment held the largest market share of the diaphragm pumps market in 2021. Diaphragm pumps find a variety of applications in the water & wastewater treatment industry and are used in feeding filter presses, digestion tanks & thickeners, and pumping stations. These pumps also find applications in wastewater treatment processes like dewatering through filtration (filter press), chemical dosing to neutralize pH levels and treat sludge, wastewater sump transfer and sample, and municipal water treatment. Diaphragm pumps can handle a wide range of debris like stones, sticks, sand, mud, or trash, and hence are ideal for water treatment applications. The wastewater from domestic and industrial sources contains harmful bacteria, viruses, nitrogen, phosphorous, and other pollutants that are harmful to the environment and human health. Hence, stringent laws on urban and industrial wastewater treatment are being introduced in Europe, North America, and the emerging economies of Asia Pacific, Middle East & Africa, and South America. This may lead to an increase in the number of wastewater treatment plants globally which may drive the demand for diaphragm pumps.

Asia Pacific likely to emerge as the largest diaphragm pumps market

The Asia Pacific region accounted for the largest share of the diaphragm pumps market in 2021. The major end users for diaphragm pumps in the Asia Pacific region include water & wastewater treatment, pharmaceuticals, chemicals, and oil & gas industries. The growth of the market in Asia Pacific, hence, can be attributed to the increasing industrialization, investments in water infrastructure, and the growth of industries like pharmaceuticals, chemicals, and oil & gas. The burgeoning population of Asia  Pacific puts an extreme burden on the water resources of the countries in this region. The water and wastewater treatment sector, as a result has huge growth potential in the region. The region is also a global pharmaceuticals hub and the industry is growing thanks to the rising awareness of healthcare in the current population and accessibility to modernized treatment regimens without border restrictions. Economies in the region are experiencing a rapid fall in their oil inventories as a result of the increasing crude oil prices and the reduction in supply induced by the sanctions on Russian crude, leading to an increase in oil & gas exploration and production activities. The growth of these industries is expected to positively drive the diaphragm pumps market in this region during the forecast period.
