What are the materials of the diaphragm?

Diaphragm is an important part of diaphragm pump and is very important. If the material is improperly selected, it will affect the use effect. The diaphragm is also a wearing part and needs to be replaced frequently. We must first understand what the diaphragm material is and what occasions it is mainly used for.

Ternary rubber: It can transport low-temperature medium, the lowest is minus 51 degrees, and it can also transport dilute acid or low-corrosion liquid.

Sando rubber: suitable for acid or alkaline corrosion, such as sodium hydroxide, sulfuric acid or hydrochloric acid, etc. It is comparable to neoprene in terms of cost performance, and this material has better wear resistance and durability.
Polyperfluoroethylene propylene: The price is higher than other materials, the corrosion resistance is very good, the flexibility is better than that of PTFE, and it is suitable for corrosive media with lower temperature.

Teflon diaphragm: It can transport more corrosive media, such as sulfuric acid, fragrances, chlorinated hydrocarbons, ketones and acetates.

Neoprene: An excellent general-purpose diaphragm for the transfer of non-corrosive liquids, such as sewage, tap or sea water, cost-effective and durable.

Butadiene nitrile rubber: used for conveying petroleum and oily liquid materials, such as leaded gasoline, diesel oil, hydraulic oil, kerosene oil, etc. It is suitable for conveying non-corrosive and thick slurries.

Understand the selection of the material of the diaphragm of the diaphragm pump, and select the appropriate material to meet the needs. Some diaphragms themselves are of good quality, but the wrong choice can cause damage. Moreover, the diaphragm pump often runs at high speed, which will also affect the quality and life of the diaphragm.

As China Molded Diaphragm Manufacturers and OEM Fabric Reinforced Diaphragms Factory , The company not only has a complete set of rubber molding products such as kneading machine, open mill, filter machine, flat vulcanizing machine, etc., but also set up a mold processing and production center, which can customize various rubbers Diaphragm for customers.
The main products: rubber diaphragm obtained national patent in 1999, the service life of more than 200,0000 times. It has certain advantages in the development of special products such as silicone rubber, fluorine rubber, nitrile rubber, ethylene propylene rubber, butyl rubber and other products resistant to nuclear radiation, high temperature resistant oil, high temperature resistant steam and various chemical media.
