The pressure resistance among several rubber hoses
Peristaltic hose is one of the necessary part for a peristaltic pump. While different usages require types of such hose. Then how many materials can used for such hose? And How to choose a proper hose? Let me introduce you next.
Peristaltic pump has wide range of usages. While the the hose is to deliver general liquid, fluid and other mixed substances. Thus in order to fit various of work, a variety of peristaltic hoses appear. Next let me show you some main materials for such hose.
Silicone peristaltic hose
The main chain of the silicone hose in the peristaltic pump consists of silicon and oxygen atoms. Thus it can bear high and low temp as well as oil. Because of such properties, it’s one of the most used material in bio and medicine. In order to strengthen the physical and chemical properties of silicone, there are 2 methods: platinum vulcanize and peroxide vulcanize.
Silicone hose is expensive. But the inner wall of the tube is smooth and has good bio compatibility. Thus it can serve as medical and sanitary grade hose.
Ordinary rubber tube
There are many kinds of rubber hoses. Besides, types of hose are suitable for variety of usages. The tolerance to organic solution is better than that of silicone hoses. But they have chemical reaction with various organic things. Besides, the property for other aspects are not that good.
Viton tube
It is a synthetic polymer elastomer. While it’s the best choice for strong corrosive and non polar solvents. But the price is very high.
From the above analyze we can see they are different for various of usages. Thus you should choose the better on based on your usage and condition.
