Standards of hydraulic hose fittings
Peristaltic pump is a common tool in food process and other industries. While in the pump, there is an important part. That is the peristaltic pump hose. In general, the peristaltic hose is a rubber hose. But recent years, the silicone hose is more popular. Then why the peristaltic pump need specific silicone tubing?
We have talked about the principle of the peristaltic pump before. The peristaltic pump uses rollers to drive the liquid in the tube forward. So this also requires that the peristaltic pump hose must be elastic. It also requires that it is able to quickly return to its original shape after extrusion. While if peristaltic hose can not return to its original state, it will cause inaccurate flow.
1. The rollers are constantly rubbing against the outer wall of the peristaltic pump hose. Therefore, the hose of the peristaltic pump must be wear-resistant. This can reduce the maintenance workload. Secondly, it can avoid increased flow, looseness and inaccuracy caused by hose wear;
2. It must have good compression resistance, which is also very necessary;
3. The peristaltic pump transmits liquid, so it must have good air tightness;
4. Many chemicals transported by peristaltic pumps are highly corrosive. Therefore, peristaltic pumps must resist corrosion. Therefore, more and more people choose silicone tubes.
5. Pharmaceutical grade certificate. USP is a globally recognized quality standards body. USP certifies the identity, potency, purity, and quality of finished dietary supplements. Products that pass USP, including GMP review, it will be awarded the “USP Certified” mark. Therefore, USP certified silicone hose is more popular for use in peristaltic pumps.
