Air operated pumps are used for pumping liquids, oil (fat), pastes or powders. Since the pumps are powered by air, they can also be used in explosion hazardous or moist areas (many pneumatic pumps meet the specifications of the ATEX Directive). Air pumps have a reduced noise level and are low in maintenance in relation to many other types of pumps.
Pneumatic pumps can be used for a wide range of applications: in the chemical industry, to pump oils, powdered substances and ink, in the foodstuff industry for sauces and liquid flavourings. Air operated pumps are used to pump lubricants, acids and cleansing agents in the automotive, offshore industry and at shipyards.
