Pneumatic pumps are framed within the category of positive displacement volumetric pumps, in which we also find currently used industrial pumps, such as industrial  peristaltic pumps or lobular pumps. There are many types of pneumatic pumps, although double diaphragm or double diaphragm pumps, patented by Jim Wilden in 1955, are one of the most widespread for industrial use. These pumps stand out for their flexibility, and low maintenance costs, which make them ideal for countless tasks. Are you thinking of modernizing your industrial equipment with a new pump? Here’s  everything you need to know about pneumatic pumps, their main uses and applications.

Operational advantages of pneumatic pumps

·         The technology of pneumatic pumps makes them incredibly versatile, allowing them to work with all types of fluids, including toxic and abrasive, flammable or corrosive products. They are also suitable for liquids with air content or with high sensitivity to cutting.

·         They are self-aspirating and can operate dry.

·         Light and easy to handle industrial pumps, with very simple maintenance.

·         Pneumatic pumps can operate with flow rates of up to 50,000 liters / hour, with discharge pressures of up to 8 bar.

·         These industrial pumps are constructed with plastic or metallic materials of great durability and resistance. For the most extreme work environments, there are also anti-corrosive versions.

Pneumatic pumps: applications and activity sectors

Pneumatic pumps allow the transfer of almost any type of fluids, from liquids to fluids with gases or solid particles in suspension. They are also able to work with toxic or corrosive fluids, so these industrial pumps are a common solution in the chemical industry, for the transfer of dyes, inks, paints, acids, solvents, alcohols, galvanic baths or ceramic slip.

The main applications of pneumatic pumps also include sludge transfer and water treatment. In addition, these pumps offer a totally aseptic working environment, since the pump does not interact with the fluid, which makes them ideal for sectors such as the food industry. Pneumatic pumps are also an excellent choice for the transfer of vegetable oils, wine, vinegar or spirits.

Accessories for pneumatic pumps

Within the current catalog of industrial pumps you can find many accessories to adapt the pneumatic pumps to the specific needs of your activity and improve the performance of your equipment, incorporating options such as pneumatic pressure regulators for flow control or pulsation damping lungs.

The pulsation damper, like the one you can find in Boyser, allows to eliminate vibrations and reduce noise, achieving more continuous flows. Using this type of equipment will be of great help to extend the useful life of your facilities, especially those of great length, in addition to allowing the use of measurement systems, such as flow meters or pressure switches. The air pressure is regulated by a pneumatic pressure reducer or with a filling valve of the automobile type. The installation of a pulsation damper is a very simple process, with variable lengths, which we can adapt according to our needs, and sanitary versions, indicated for the food, pharmaceutical or cosmetic industry.
