The operation of a double diaphragm pump, or pneumatic diaphragm pump, is both simple and effective: they are pneumatic pumps suitable for transferring fluids with reciprocating motion.
The pneumatic diaphragm pumps are equipped with two opposing pumping chambers, hermetically divided into two, one in contact with the compressed air and the other in contact with the pumped fluid.
The diaphragms, placed between two pumping chambers and activated by the pneumatic motor, and the valves, designed to ensure the total passage of the fluid both inlet and outlet, are the only parts in contact with the fluid.
Air operated double diaphragm pumps, or air operated diaphragm pumps, are designed and manufactured to pump a wide range of fluids even with high viscosities and with suspended solids.
They can also be used for heavy-duty applications such as environments with high humidity or potentially explosive atmospheres thanks to the ATEX Directive with which they are equipped.
Unlike other types of pumps, the diaphragm pump for liquids has no limits of use, also adapting to dry operations, to mix fluids, in self-priming and submerged.
Years of experience make Fluimac the ideal choice as a partner for your business. As all operators in the sector know, there are many needs that require the safe use of a diaphragm pump, also called pneumatic double diaphragm pump, diaphragm pump or air pump. From the chemical sector and pharmaceutical to food
diaphragm pumps are used in many processes that need to transfer liquids; even in the presence of an environment made aggressive by the saturation of chemical products. Fluimac has in its catalog a wide range of pneumatic pumps to meet the needs of any type of processing.
The diaphragm pump
It is the ideal type of pump for moving dirty fluids with very high apparent viscosities and also with suspended solid parts. The construction method of these pumps gives them stability and safety, ensuring safe operation without the need for lubricated air. The processing speed can be adjusted, as can the capacity of
draft for unprecedented versatility of use. The quality of the materials used in the construction of the various models of Fluimac diaphragm pumps makes the pneumatic diaphragm pumps suitable and certified for use in hazardous areas and highly saturated with products
aggressive:
