Peristaltic pumps have been used for pumping materials in laboratories once they have been developed due to their good sealing properties. With the advancement of science and technology, peristaltic pumps are gradually used in construction engineering, food engineering and other industries. The peristaltic pump is mainly composed of three parts: driver, pump head and hose. The hose is the only loss part, which greatly reduces the cost of repairing equipment. We are mainly here to talk about the advantages and disadvantages of the hose pump and its main application, which can help us better, understand the peristaltic pump and reduce the damage to the equipment.

The working principle of peristaltic pump:

The peristaltic pump is called a peristaltic pump because its behavior mimics the digestion process of the intestines when people and animals swallow food and liquid. When the peristaltic pump pumps materials, the opening and closing of the tube on the peristaltic pump moves the material forward. When the material moves internally, when it is transported to the vacuum outlet, the material will be transported out of the pump port. The size of the tube, the amount of material being transported and the speed of the roller determine the flow rate of the peristaltic pump, which allows you to precisely control the moving speed and quantity of the material.

Advantages of peristaltic pumps：

1. Zero pollution

The peristaltic pump is designed and configured to ensure that the supplied fluid always flows through the pump tube. There are two reasons for this design: one is that the liquid is not contaminated by the pump, and the other is that the pump is not contaminated by the liquid. This is especially useful for transporting corrosive liquids and high purity chemicals. It is very easy to choose a chemically compatible pump with a specific solution, because the liquid does not come into contact with gears, sealing elements, diaphragm elements or other moving parts, so when transporting corrosive materials, just consider the characteristics of the hose.

2. Low loss

Because only the pump tube is a water-passing part, there is no need to worry about corrosion, wear and loss of other parts. Therefore, when transporting abrasive fluids, a peristaltic pump is the best choice. The moving parts of other types of pumps are easily worn out when transporting this type of fluid, which leads to frequent replacement of the above-mentioned parts and increases the potential for component failure.

Peristaltic pumps have also been successfully used to transport solutions that tend to settle or harden. When cleaning after use, only need to flush or replace the hose.

Application of peristaltic pump：

We will briefly introduce the application of peristaltic pumps, because there are too many uses for peristaltic pumps, so our summary may not be very complete. Peristaltic pumps are used for pizza sauce preparation, juice production and vitamin injection. It is also used for the circulation of suspended solids in the fermentation process. It is used for uptake in tissue and cell culture. Peristaltic pumps can be used to spray paint, transport sterile media, acidic or alkaline media, fuels and lubricants. Peristaltic pumps are also used to produce circuit boards and adhesives. Generally, if the transported materials have purity and precision requirements, a peristaltic pump is also the best choice.
