PE PA and PP corrugated hose look the same but quite different from each other
As one of the core part of a peristaltic pump, the peristaltic pump hose is crucial. It directly affects the efficiency, service life of the pump and the purity of the medium.
First of all, we need to make it clear that the material selection of pump hoses is not purely about high performance. Instead, find a balance between performance and cost. An ideal pump hose should be pressure and corrosion resistant. Besides, it should not be easy to age. On this basis, we Everflex recommends three types of peristaltic pump hose.
Silicone tube
The main chain of the silicone tube in the peristaltic pump contains silicone rubber, which is composed of alternating silicon and oxygen atoms. It has high-quality properties of high resistance, low resistance and oil resistance. Silicone tube is one of the most common tubes in the biopharmaceutical industry. There are generally two treatment methods, platinum cure and peroxide cure. Silicone hose is more expensive than other materials. But the inner wall is smooth. Thus it can reduce fluid resistance and improve pumping efficiency.
Fluorine rubber tube
Fluorine rubber pipe has excellent corrosion resistance. So it is the best choice to transport highly corrosive and non-polar solvents. However, such hose is not that flexible and wear resistant. Despite its higher cost, fluorine rubber hose is irreplaceable in certain industries.
PTFE tube
PTFE hose has excellent chemical stability, temperature resistance and low friction coefficient. However, Teflon hose has poor flexibility and is easy to break. Therefore, its advantages and disadvantages need to be weighed when choosing.
