Today I will introduce to you: five kinds of coatings commonly used in screw vacuum pumps


Screw vacuum pump is now more and more popular, I believe that the follow-up will only be more commonly used, especially in the future to

 achieve the mass production of screw vacuum pump, the cost of the decline so that the majority of customers on its acceptance will only be 

better. The use of screw vacuum pump can not be separated from the anti-corrosion coating, today Weidu Fluid Equipment (Jiangsu) Co., Ltd. 

to talk about several commonly used coating of screw vacuum pump.

At present, these five coatings are mainly on the market:

1, PTFE coating (PTFE is also called polytetrafluoroethylene), this coating is relatively thin, corrosion resistance is general, wear resistance is gene

ral;

2, PFA coating (PFA also known as fluoroalkylate or teflon), its thickness can be selected according to the working condition, has good corrosion

 resistance, wear resistance;

3, PEEK coating (PEEK is also known as polyether ether ketone), the current application range is very wide, has good corrosion resistance and 

wear resistance, many conditions are used to replace PFA coating;

4, nickel plating or nickel phosphorus coating, has good corrosion resistance and wear resistance, but not suitable for strong corrosion;

5, Hastelloy coating, has strong corrosion resistance and wear resistance, corrosion resistance is stronger than nickel plating or nickel phosphor

us coating, but for strong corrosion conditions, it will be corroded for a long time.

The application of these coatings sometimes even determines the use and service life of the pump, so we should select according to our own 

needs.
