A peristaltic pump is a fluid delivery device that works by pushing fluid through a compression and release hose. Peristaltic pumps are favored for their excellent flow control capabilities and are now widely used in chemical, food, pharmaceutical, water treatment and other industries. In this article, we will have an in-depth discussion on the principle, classification, application, advantages and other aspects of peristaltic pump, to help you better understand the peristaltic pump, so that your fluid control more accurate!

1, the principle and classification of peristaltic pump

The principle of peristaltic pump is to push the working principle of the fluid through the compression and expansion of the peristaltic pump hose. The hose of peristaltic pump is generally made of wear-resistant thermoplastic elastomer, and the pressure roller is installed on both sides of the hose. When the pressure roller compresses the hose, the fluid in the hose will be pushed to the outlet; When the pressure roller is loosened, the hose will automatically rebound and absorb the external fluid, completing the process of a fluid transport.

According to the supporting equipment and use of peristaltic pump, peristaltic pump can be divided into manual peristaltic pump, motor driven peristaltic pump, gear driven peristaltic pump and other types. Manual peristaltic pumps are generally used for laboratory or sample transportation, equipped with sampler, reactor and other accessories. Motor driven peristaltic pump and gear driven peristaltic pump are widely used in industrial fluid transport.

2, the application and advantages of peristaltic pump

In different fields, peristaltic pumps have a wide range of applications. The following are to introduce the application and advantages of peristaltic pump in chemical, food, pharmaceutical, water treatment and other industries.

(1) Chemical industry

In the chemical industry, peristaltic pumps are mainly used to transport corrosive, viscous and other difficult to transport media. Because the fluid transported by the peristaltic pump is completely isolated from the hose, there will be no leakage problem, so it is very suitable for the transportation of dangerous chemicals.

(2) Food industry

In the food industry, the peristaltic pump is a very excellent fluid transport equipment. Because the peristaltic pump itself is simple in structure and does not require any sealing parts, it will not cause secondary pollution to food, and can transport drinks and juices containing solid particles, etc., under the premise of ensuring food hygiene, it is very suitable for the use of the food industry.

(3) Pharmaceutical industry

In the pharmaceutical industry, peristaltic pumps are also a commonly used fluid delivery equipment. Peristaltic pumps can transport a variety of different solutions, including proteins, suspensions, emulsions, etc. Because the peristaltic pump is a volume pump that can control the flow very accurately and is very convenient to use, it has been widely used in the pharmaceutical industry.

(4) Water treatment industry

In the water treatment industry, peristaltic pumps are widely used in sewage treatment, water treatment and other fields. Because the hose of peristaltic pump has wear-resistant and corrosion-resistant characteristics, it can transport sewage with particulate matter, and the flow control is very accurate, so it has been widely used in the water treatment industry.

3, the advantages of peristaltic pump

Peristaltic pump has the following advantages:

(1) Small size, simple structure: peristaltic pump structure is relatively simple, can reduce maintenance costs.

(2) Precise flow control: the peristaltic pump is a volume pump that can control the flow very precisely when transporting fluids.

(3) Strong suction capacity: the peristaltic pump has a strong suction capacity and can lift the medium from a relatively low liquid level.

(4) Can transport a variety of media: peristaltic pump can transport a variety of media, including liquid, gas, liquid-solid two-phase flow.

(5) The transmission process will not change the nature of the medium: because the peristaltic pump is a volume pump, the transmission process will not change the nature of the medium.

4. Conclusion

In summary, peristaltic pump as a new type of fluid transport equipment, its advantage is that the flow control is accurate, can transport a variety of different media, in chemical, food, pharmaceutical, water treatment and other industries have been widely used. Through in-depth understanding of the principle, classification, application, advantages and other aspects of peristaltic pump, I believe that everyone has a more comprehensive understanding, can better apply peristaltic pump, so that fluid transport becomes more accurate!
