Peristaltic pump is a kind of rotor positive displacement pump. Compared with other types of pumps, it can pump three types of objects: solid, liquid and gas. Peristaltic pump imitates the intestinal food and digestion process of human or animal. When food enters the intestines and stomach, the intestines will peristaltic digestion. The same is true for the peristaltic pump. The hose is equivalent to the intestine and will transport the pumped substances intact. Due to its low shear force and characteristics of high corrosively, the peristaltic pump is widely used in the construction industry, water treatment, paper industry, metallurgical industry, etc. We will talk about the reasons why peristaltic pumps are widely used in the paper industry.

Peristaltic pump deadline is usually 7 to 10 years, the use of one of the decisive role is the quality of the hose, common types of hose to have excellent antiwar properties of natural rubber, oil, lubricating oil, alkaline liquid NBR and detergent, have excellent wear resistance can be conveying acid and alcohol of ternary ethylene propylene rubber. We also provide high pressure hose with excellent wear resistance, steel wire reinforced inner layer, can withstand up to 3MPa.

 Papermaking industry is closely related to people's life and is an industry with development potential. Papermaking is mainly based on wood as the main raw material, adding the corresponding chemical agents in the production process, to produce white or other colors of paper. Peristaltic pump in the paper industry is mainly used to pump chemical agents.

Peristaltic pump is widely used in paper industry for the following reasons:

1. During pulping, bleaching chemicals such as chlorine, caustic soda, peroxide, hypoglycemia, carbon monoxide and oxygen will be added, which may lead to empty operation. Compared with other pumps, peristaltic pump can be empty operation, and no damage to the pump body.

2. Organic fillers such as talcum powder, calcium carbonate, kaolin, titanium dioxide, etc. are used in the process of papermaking. They are highly corrosive and will cause certain damage to the pump body. Peristaltic pump has corrosion resistance characteristics, the only contact with the pumped material is the hose, even if the damage, only need to replace the hose.

3. The process of papermaking needs to use melamine formaldehyde resin, PAE, PPE, polyacrylamide, urea-formaldehyde resin and other wet reinforces, which need to be accurate to the specific grams when added. Peristaltic pump can be used for accurate pumping, and the amount of materials can be accurately controlled, and waste can also be reduced.

4. Dry operation without liquid will not damage any part of the pump. Peristaltic pumps can produce up to 98% vacuum. There are no valves, mechanical seals or packaging seals, so there is no leakage or maintenance. It can also easily transport solids, liquids or gas-liquid mixtures, up to 40% of the diameter of the solids contained in the fluid.
