CIP Return Pump Application: CIP reflux pumps are widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments, playing a great role in improving product quality, reducing leakage, preventing pollution and improving the environment. How does it achieve a high sealing state? This question can be explained from the following two aspects.

1. Sealing form

For static seals, there are usually only two forms: gaskets and sealing rings, and o-rings are the most widely used sealing rings; for dynamic seals, CIP reflux pumps rarely use packing seals, and mainly use mechanical seals. Mechanical seals are divided into single-end and double-end, balanced and unbalanced types. Balanced type is suitable for sealing high-pressure media (usually refers to pressure greater than 1.0mpa), and double-end mechanical seals are mainly used for high-temperature, easy-to-crystallize, viscous, particle-containing and toxic volatile media. Double-end mechanical seals should inject isolation liquid into the sealing cavity, and its pressure is generally 0.07~0.1mpa higher than the medium pressure.

2. Sealing material

The material of CIP reflux pump static seals is generally fluorine rubber, and polytetrafluoroethylene materials are used in special cases; the material configuration of mechanical seal dynamic and static rings is more critical, and it is not the best for cemented carbide to cemented carbide. The high price is one aspect, and it is not reasonable that there is no hardness difference between the two, so it is best to treat them differently according to the characteristics of the medium.
