What is a peristaltic pump? What can it be used for?

A peristaltic pump is a volumetric pump for small and medium flow liquids. This pump is easy to install and consists of only three parts: a driver, a pump head, and a hose. Among these three parts, only the hose needs to be replaced regularly, and the others do not. Here I will share with you some small knowledge about peristaltic pumps.

1. Principle of peristaltic pump

The above has clearly explained the concept of peristaltic pumps. Peristaltic pumps mainly squeeze the hose through rollers to form self-priming pressure inside the hose, suck the liquid into the hose, and transport the liquid to the outlet as the rollers rotate.

2. Pressure

The pressure of the peristaltic pump is formed by the roller squeezing, so the pressure of the peristaltic pump will naturally not be too strong, so it is mostly used for liquid transmission, high-viscosity liquids, or production sites with high pressure requirements. The effect of peristaltic pumps will not be too good.

3. Wide application

The main transmission tool of the peristaltic pump is the hose, so the only contact with the transmission liquid is the inner wall of the hose. The hose is made of various materials, which are resistant to high temperature, corrosion, and strong in stability. Different hoses are suitable for different occasions and can be replaced according to the different liquids you need to transmit.

4. Matching

Because the peristaltic pump is small, it is often used to match other equipment, such as online mixing systems and filling lines, which are matched with the whole peristaltic pump. Equipment such as debridement machines or fermentation tanks are used in conjunction with peristaltic pump heads and OEM.
