The most innovative pump in this era is Pneumatic diaphragm pump. This is new transport machinery which is currently one of the most used in both industrial and domestic use.By using compressed gas as a power source, a variety of chemicals, corrosive, high viscous, volatile, flammable, poisonous liquid can be pumped without optical exhaustion.
In BSK four types of pneumatic diaphragm pumps are available ie, Poly propylene, aluminum, cast iron and stainless steel body and the diaphragms are chosen based on the on the liquid medium. The available options are nitrile rubber, neoprene, Viton, Teflon.
The main advantage of AODD pumps are, it can pump a variety of media which the conventional pumps cannot be used and highly flammable liquids as it is using air as the energy source.
