The hose is the core part of the peristaltic pump and one of its important consumables. The hose is mainly used to pump liquid, gas or liquid-gas-solid mixture. In general, the factors affecting the service life of peristaltic pumps are the compression method, compression force, number of times of compression, and thermal fatigue wear caused by repeated use, which are all related to the service life of peristaltic pump tubes. have a lot to do with it.

The inner and outer diameters of the peristaltic pump hose also have a great influence on the operation of the fluid pumping system, that is, the peristaltic pump. The inner diameter determines the amount of fluid pumped per rotor revolution and the wall thickness determines the ability of the tubing to return to its original shape after each crush. This is also one of the factors affecting its service life, so in order to save the cost of use, special attention should be paid to selecting the appropriate peristaltic pump hose. This is also the main reason why many customers report that the pump tubes on the market are not durable!

Features of peristaltic pump hose:

1. Good flexibility and resilience, that is, the hose can quickly recover its shape after being radially compressed. If the pipe is too hard, it will put unnecessary load on the motor which may reduce the life of the pump or cause it to stop running.

2. It has good high wear resistance, high compression and tear resistance; it can meet food hygiene and other testing standards.

3. Good air tightness and no leakage; the inner wall is smooth and not easy to adhere to particles. If the inner wall is squeezed for a long time, the inner wall will not stick.

4. Low adsorption, good temperature resistance, not easy to age, not swelling, corrosion resistance, low precipitates, etc.
