Corrosion resistant vacuum pump material

Looking for corrosion-resistant vacuum pump materials, stainless steel water ring vacuum pump is a kind of water ring pump with stainless steel as vacuum pump material, which has corrosion resistance. Among the corrosion-resistant materials of vacuum pump, the price of stainless steel vacuum pump is moderate. For example, stainless steel is a little more expensive than ordinary (non corrosion resistant) water ring pump, and stainless steel vacuum pump is much cheaper than titanium vacuum pump. In a word, according to the working conditions, stainless steel can be used as a whole, or stainless steel can be used for flow passage parts or impellers.

Corrosion resistant vacuum pump material, stainless steel interpretation:

Stainless steel is the abbreviation of stainless steel, which is resistant to weak corrosive media such as air, steam, water, etc., or stainless steel; and the steel that is resistant to chemical corrosion medium (acid, alkali, salt and other chemical etching) is called acid resistant steel.

Due to the difference in chemical composition, the corrosion resistance of the two steels is different. Ordinary stainless steels are generally not resistant to chemical medium corrosion, while acid resistant steels are generally stainless. The term “stainless steel” not only refers to a kind of stainless steel, but also refers to more than 100 kinds of industrial stainless steel. Each kind of stainless steel developed has good performance in its specific application field. The key to success is to find out the use first, and then determine the correct steel grade. Generally, there are only six kinds of steel related to the application field of building construction. They all contain 17-22% chromium, and the better steels also contain nickel. The addition of molybdenum can further improve the atmospheric corrosion resistance, especially the corrosion resistance of chloride containing atmosphere.

Stainless steel refers to the steel which is resistant to the corrosion of weak corrosive media such as air, steam, water and acid, alkali, salt and other chemical corrosive media, also known as stainless acid resistant steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, while the steel resistant to chemical medium corrosion is called acid resistant steel. Due to the difference in chemical composition, the former is not necessarily resistant to chemical medium corrosion, while the latter is generally rust free. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.

Two kinds of stainless steel are commonly used in EVP stainless steel water ring vacuum pump

304: general model; i.e. 18 / 8 stainless steel. Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment. The standard composition is 18% chromium and 8% nickel. It is a non-magnetic stainless steel which can not be changed by heat treatment.

316 L: low carbon, so it is more corrosion resistant and easy to heat treatment. Products such as: chemical processing equipment, nuclear power generator, refrigerant storage. (Note: other types of stainless steel are also used.)

Stainless steel water ring vacuum pump, EVP vacuum pump material options:

Impeller stainless steel: impeller stainless steel material has 304 stainless steel, 316 stainless steel, 316L stainless steel.

Stainless steel flow parts: pump body, disc, impeller are 304 stainless steel, 316 stainless steel, 316L stainless steel.

Overall stainless steel: pump body, disc, impeller, pump cover, pump shaft are 304 stainless steel, 316 stainless steel, 316L stainless steel; pump body, disc, impeller, pump cover, pump shaft, connecting pipe, upper steam water separator, etc.

Stainless steel vacuum pump manufacturer EVP is a very professional vacuum pump manufacturer. If you have corrosive chemical components in your working conditions, you need to find corrosion-resistant vacuum pump materials. The correct way is to communicate with EVP technicians and make technical evaluation on material selection. In short, stainless steel vacuum pump is a good choice.
