Working Principles

Pumps that require a pressurized air source to work in a healthy way are often called air pumps. In the design of this type of pumps, two diaphragms can be mentioned as opposite. Because of this situation, air operated pumps are sometimes referred to as diaphragm pumps and are directly evaluated in this category.

On the other hand, since some diaphragm pumps can also work with electricity, it would be more appropriate to use the term air/diaphragm pump in order to avoid confusion. Air/diaphragm pumps are considered as extremely attractive and advantageous pumps in terms of their principles. In this type of pumps, apart from the diaphragms mentioned above, there are also two liquid chambers. It is seen that the diaphragms in air diaphragm pumps are connected to each other with the shaft.

The filling of the compressed air to the directional valve takes place with the support of the compressor. In this way, pressurized air is transferred directly to the back of the diaphragm. The said pressure is transmitted to the liquid in the first chamber thanks to the diaphragm. The fluid is pressurized in this process, and as a result, the diaphragm begins to move.

Usage areas

Areas where compressed air supply is mostly in the range of 6-8 bar are quite ideal for this type of pump. Of course, it is possible to reach pressure values suitable for the name of the pump by using pressure reducing valves.

The working principles of air/diaphragm pumps are more like suction pumps. The propulsion method is not by electric motor but by compressed air. It has non-explosion feature thanks to its non-electrical operation. Exactly for this reason, it is used with peace of mind in the transfer processes of fluids such as solvents or fuel oil. Its ability to absorb deeply makes it preferred in different areas.

Today, air diaphragm pumps are mostly; It is used in petrochemical facilities, food processing areas, ceramic production, shipyards, water treatment areas, sawdust production facilities, and the pharmaceutical industry.

Pay Attention to These While Buying an Air Operated Diaphragm Pump

When choosing air diaphragm pumps, it is useful to pay attention to certain criteria. For example, it is important to identify the fluid that will be transferred. On the other hand, you also need to define the flow and pressure needed. Analyze the temperature values with the cleaning fluid. After verifying the viscosity, inspect the maximum size on the solid part.
