If a water ring vacuum pump is to be used, it is recommended to opt for 316L material; 304 can be used for both types, but its service life is likely to be short

Besides liquid ring pumps, what other types of vacuum pumps are suitable?

Then there are dry oil-free vacuum pumps, with anti-corrosion treatment applied inside. Our company currently offers two special coatings for you to choose from: new materials and Hastelloy. You can refer to the company’s website at www.sdtlhs.com
