Diaphragm pumps are used in different applications in every field of industry. Diaphragm pumps working with compressor air can be produced in different sizes in the range of 0-895 lt/min. Since there is no electrical component, it has an ex-proof feature. For this reason, ATEX can be used easily in many desired applications. Air pumps provide great convenience to the user in the cleaning process of oil and sludge formed in petroleum products tanks. It is widely used in transfer and circulation of all kinds of chemicals, adhesives, solvents, paints and inks. Air pumps work without electricity. Thus, it has ex-proof feature that is safe against fire and explosion. It is used for the storage and transfer of paint and glue raw materials. Nitrile Rubber (Buna-N) diaphragm for water-based fluids and PTFE (Teflon®️) diaphragm types for solvent-based fluids are suitable for the usage process. Air pumps are widely used in the food industry. The fact that it does not deteriorate or thin the chemical properties of the liquid it transfers has made it an indispensable pump for transferring and storing sensitive liquids such as milk, buttermilk, cream, mustard, mayonnaise and ketchup. There are air pumps suitable for food regulations for the transfer of dense materials such as chocolate and marmalade. Air pumps are used in the ceramic industry for mud transfer and filling into molds. In addition, it is used for circulation and spraying in the glaze coating process. They are widely used in shipyards, shipbuilding and repair. In the discharge of wise water, sandblasting and scraping wastes, rusty wastes are among the areas of use of air pumps. Air pumps are used in the transfer and storage of many chemical substances in dyehouses in the textile sector and in the circulation of dyes of printing machines. According to the printing and color capacity of the machine, a separate air pump for each color is used as a paint pump. They are used in machining, in the transfer of boron oils, in painting booths, in the removal of spray waste residues and paints, in auto service stations, in the collection of sump waste and burnt oil, in pumping industrial wastes and sewage to treatment plants. Air pumps are used in the transfer of sludge produced in treatment plants and containing various acid and chemical wastes, and in the dewatering of sedimentation sludge from sedimentation ponds by pressing filter presses. Pumps used in filter presses can compress the press up to 16 bar. Air pumps are used in the transfer of animal wastes generated in livestock slaughtering facilities, in storage and bottling processes in fish oil production facilities.
