There are many industries that make use of pneumatic pumps for their processes. These pumps have received positive responses regarding their practicality and efficiency. However, in order to take advantage of the product, it is helpful to know a few important facts about this type of pump.
Diaphragms for the Pumps
Diaphragms are often considered as a weak component for the pumps. It is essential to find a diaphragm that is strong and will last for a long period of time. This is because the pumps depend on the diaphragm in order for the units to operate continuously. The great news is that there are reliable diaphragms that are available today which come with excellent designs and make use of robust materials to make them durable. Other factors that affect the life of the diaphragm include the corrosiveness of the medium that needs to be pumped and the temperature as well.
Main Features of the Pumps
A pneumatic pump is quite useful for many industries because it possesses proficient features including being self-suctioning and is volumetric which denotes that it can be used similar to a dosifier pump. Aside from that, it is flexible based on its flow rate which can go from zero to its maximum level. Such a pump can be used for a variety of applications even in explosive environments. As a matter of fact, this type of pump can efficiently manage high and charged viscosity liquids.
Two Principal Forms
There are two main types of these pumps namely piston and membrane pumps. A membrane pneumatic pump is the one that makes use of two membranes in order for it to function. These two membranes are outfitted on a shaft that moves in different directions.
On the other hand, pneumatic piston pumps use a piston which is connected to a moving shaft. This particular shaft is connected to the engine that is pneumatically powered. Many industries choose piston pumps because of there are more advantages which they offer in comparison to membrane pumps. According to recent tests, the piston almost never fails so that work will not be disrupted due to issues with the pump. Additionally, output pressures are higher than compressed air pressure. This can be achieved if the piston diameter is significantly smaller than the pneumatic engine cylinder. Users are also allowed to use one engine to simultaneously move more than a single pump. This permits the setting up of several components for dosing systems.
Needless to say, pneumatic pumps can be very useful especially for gas and oil production. It is important however to choose the product to use carefully. The pump should have positive displacement and should be able to exhibit excellent durability.
