Introduction to the Design Advantages and Classification of Peristaltic Pumps

In the past, peristaltic pumps were almost exclusively used in laboratories. But after redesigning, its flow rate and pressure have been improved. Now, a large number of peristaltic pumps have been successfully applied in the field of chemical process control and production.

The popularity of the peristaltic pump can be attributed to its design, which uses a motor to drive a set of rollers to rotate. The rollers successively run over the soft peristaltic pump tube, compressing and releasing it repeatedly. This squeezing action creates a vacuum, sucking fluid in and passing through the peristaltic pump tube, thereby completing the pumping process. Because only the peristaltic pump tube is the water-passing part, maintenance and cleaning are simple and convenient. And there are more and more peristaltic pump manufacturers.

Ⅰ. Design advantages of peristaltic pump

The design and configuration of the peristaltic pump can make the conveyed fluid always flow in the pump tube.

This is very important for two reasons: one is that the fluid will not contaminate the pump; the other is that the pump will not contaminate the fluid. This is particularly advantageous when transporting chemically corrosive fluids or high-purity fluids.

Since the fluid will not contact gears, sealing elements, diaphragm elements or other moving parts, it is very simple to select a chemically compatible peristaltic pump for a specific solution. Just choose a small peristaltic pump tube that is chemically compatible with the solution.

Most peristaltic pumps require very little maintenance to keep them in good working condition. The peristaltic pump tubing must be replaced regularly to prevent leakage or decrease in flow. The replacement process generally only takes a few seconds, which is an advantage when the same peristaltic pump is used to transport or dispense different chemical solutions.

After changing the solution, only need to replace the peristaltic pump tube. It only takes a few minutes to start and run the peristaltic pump again, which saves time and labor. Moreover, the same peristaltic pump can be used for different chemical processes, which greatly saves costs.

Ⅱ. Peristaltic pumps can be divided into the following types based on operation and use:

1. Speed-regulating peristaltic pump

It has the basic control functions of a peristaltic pump, displaying speed, start-stop direction, speed adjustment, filling and emptying, power-down memory, external control input and other functions.

2. Flow type peristaltic pump

In addition to basic functions, functions such as flow display, flow correction, and communication are added.

3. Distributing peristaltic pump

In addition to basic control functions, functions such as flow display, flow correction, communication, liquid volume distribution, suction, and output control are added.

4. Customized peristaltic pump (OEM)

With a series of peristaltic pump heads with different flow ranges, customers can design different peristaltic pump drive circuits for supporting use according to their own equipment requirements.
