BlSS Chemical Pump And Chemical Compatibilityogs

We have heard a lot about chemical pumps. But do you know, that the pumps need to have excellent chemical compatibility? Now, what is chemical compatibility? It is the resistance of exposed metals to corrosion and causing damage. As one of the leading Chemical Centrifugal Pump Manufacturers in Ahmedabad Vadodara Gujarat, VND Plastico Pumps Pvt. Ltd. The effect on the surface can depend on temperature, abrasive type, inert gases, etc. As the seals and shafts of the pump come in direct contact with the fluids, corrosive in nature, it is very important that the exposed materials have chemical compatibility.

Types Of Pump Corrosions

The pump needs to be chemically compatible. The lack of compatibility will make parts of the pump erode at a very faster rate. Although, there are various types of corrosion and reasons related to it. Here are some of the common types of corrosions mentioned below:

• Uniform Corrosion: The exposed metal component faces consistent and constant deterioration. This is one of the predictable corrosions, thus helping in estimating the operational lifetime of a pump. A coat of protective layer or use of corrosion resistant construction material can help in minimizing the corrosion effect. 
• Galvanic Corrosion: Different bare metal surface is the cause of such corrosion. Thus, to prevent such corrosion, it is important to access the pumping fluid in the system, valves, and pipes.
• Pitting Corrosion: It is the damage that is caused after the protective layer is damaged. The removal of the layer makes the metal surface exposed and thus, prone to corrosion. Further, the irregular pits with sharp edges can create problems for the components.
• Stress Corrosion: The stresses in the components can also lead to corrosion. Thus, stress corrosion and mechanical stress altogether can lead to pump breakdown.
• Inter-Granular Corrosion: The corrosion around the grain boundaries is termed as Inter-Granular Corrosion. This type is very much common in stainless steel pump welds and castings. 
• Crevice Corrosion: This condition may arise because of stagnant fluids in the pump system. If we talk about an example, we can consider the condition around the flanges. 
• Microbiologically Influenced Corrosion: This is a corrosion type witnessed in pumps that are used for the handling of untreated water. There are some bacteria that are said to induce corrosion and promote the same.

Ways To Prevent Corrosion

The components of the pump, namely shafts, plungers, impellers, sleeves, piston rods, containment shells, etc., are made of metallic, non-metallic, or ceramic compounds. In addition to this, a proper protection layer on the exposed surface also ensure the protection of the pump from corrosion.

There are Industrial Pumps and SS Chemical Pump Manufacturers in India, who are praised for delivering pumps that meet the requirements of the application areas and also meet the set international standards. They also provide after sales services, in which h they deploy a team of experts, who look into the working and maintenance of the pumps. Although, the pumps are manufactured using corrosion resistant materials. Some of them are also provided with extra protection coatingin creases crease the service life of the pumps employed for heavy industrial activities.
