The principle of a peristaltic pump is that the runner squeezes the pump tube and rotates to push the fluid in the tubing forward to generate fluid flow, just like using two fingers to squeeze a hose filled with liquid. Moving, negative pressure is formed in the tube, and the liquid flows with it. Therefore, the peristaltic pump is a positive displacement pump. The liquid in the pump tube is pushed out by the runner of the pump head. After the runner leaves, the pump tube will rebound stably to suck in new liquid. Our peristaltic pump head will produce a constant flow rate for each revolution, and the flow rate will increase by the same revolution for each revolution in a unit of time. Therefore, the flow rate generated by the peristaltic pump at the specified speed is constant. Because the peristaltic pump has this characteristic, users often refer to the peristaltic pump as a constant flow pump.

The advantages of constant flow pumps are as follows:
1. Clean and pollution-free: the fluid only passes through and touches the peristaltic pump hose.
2. High precision: constant current, reproducibility up to 0.5%, flow can be adjusted accurately.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: It can transport various fluids, such as organic solvents and corrosive liquids.
5. It can run dry and dry: it can also transport air or gas-liquid-solid three-phase mixed transport.
6, with self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of the shut-off valve, no siphon, no seals, shut-off valve, and check valve function.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9, Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
10. It can withstand higher temperatures: the peristaltic pump can continuously deliver liquids at 80 degrees Celsius.
