I’m a newcomer to this industry and would like some advice on choosing medium-pressure pumps. I hope those with more experience will be kind enough to share their insights

When selecting a pump for these eight media—N,N-dimethylformamide, ethyl acetate, dimethyl carbonate, butanediol, ethylene glycol, diethylene glycol, and methylpropylene glycol—what materials could be considered? Should we consider the sealing issue of the pump? What materials can be used for sealing? I’m a newcomer; I’ve looked up their physical properties, but I still lack confidence when it comes to actually using them. I hope everyone can share their thoughts. Thank you.
If we consider only the names of the fluids handled by these eight types of pumps, they are generally all flammable and volatile, as well as **. When choosing a pump type, it is recommended to consider magnetic pumps and shielded pumps. As for the material to be used, it depends on the specific operating conditions and working temperature. The following are those I have come into contact with: (for reference only) N,N-Dimethylacetamide, Ethyl acetate, Diglycol, Methylpropylene glycol: Fluorinated lining (magnetic pump); Butanediol, Ethylene glycol: Stainless steel 304 (centrifugal pump, magnetic pump); Amines, Butadiene, Dimethyl carbonate: (magnetic pump, shielded pump)

So I thought that magnetic pumps, shielded pumps, stainless steel, or fluorinated coatings might not be necessary to consider. But after hearing what you said, I’m confused again. Are you from a equipment manufacturer? Do you have any samples? Could you send one to me? My QQ number is XXXX; I’m in the Haichuan QQ group
