The Impact of Peristaltic Pump Silicone Tubing on Peristaltic Pump Performance

The tubing is a core component of the peristaltic pump and one of its important consumables. It is mainly used to pump liquids, gases, or mixtures of liquids, gases, and solids. Generally speaking, factors affecting the service life of a peristaltic pump, in addition to the squeezing friction between the pump head and the tubing, include the compression method, compression force, number of compressions, and thermal fatigue wear caused by repeated use. These are all significantly related to the service life of the peristaltic pump tubing.  

Characteristics of Peristaltic Pump Tubing:

1. Good flexibility and resilience, meaning the tubing can quickly return to its original shape after being compressed radially. If the tubing is too hard, it will add unnecessary load to the motor, which may reduce the pump's service life or cause it to stop running.  

2. Good high wear resistance, high compression and tear resistance; can meet food hygiene and other testing standards.

3. Good air tightness, no leakage; smooth inner wall, not easy to adhere to particles, and the inner wall will not stick together after long-term extrusion.

4. Low adsorption, good temperature resistance, not easy to age, does not swell, corrosion resistant, low extractables, etc.

The inner and outer diameter dimensions of the peristaltic pump tubing also have a great impact on the fluid pumping system, that is, the operation of the peristaltic pump. The inner diameter determines the amount of fluid pumped per revolution of the rotor, while the wall thickness determines the ability of the pump tube to return to its original shape after each squeeze. This is also one of the factors affecting its service life. Therefore, in order to save usage costs, it is especially important to choose the appropriate peristaltic pump tubing. This is also the main reason why many customers report that the pump tubing on the market is not durable!
