The liquid ring vacuum pump required in this process system; process conditions: medium to be evacuated: HCl gas, along with trace amounts of siloxane and ethanol. System vacuum level: -0.07 to -0.09 MPA. Pumping capacity: 2500 m3/h. The pressure at the outlet of the vacuum pump is slightly positive, around 10 to 25 kPa. Currently, we are considering using two types of vacuum pumps: one that uses concentrated sulfuric acid as the working fluid, and the other that uses water as the working fluid. The former is made of carbon steel and its approximate model is a 2BE1 type vacuum pump; the latter uses FSK-15 vacuum pumps connected in parallel. We would appreciate it if everyone could share their opinions and provide information about the manufacturers. Thank you! My QQ is 171625654
Well-known domestic manufacturers of liquid ring vacuum pumps include Foshan Water Pump Factory and Zibo Vacuum Equipment Factory. The medium is highly corrosive; it is best to discuss this with the supplier, as they have extensive experience in this area.
Geditnas Company, as well as the Kurimura Vacuum Pumps of the Japanese Tsurumi Group
The products from “Kenfulai” in Foshan, Guangdong are good; we will use products from this company
Hello, I recommend using water as the circulating fluid. With concentrated sulfuric acid, if the system isn’t properly sealed, its concentration will decrease, and it will be necessary to replace the pump within a week. Unless materials with excellent corrosion resistance are used, such as fiberglass, these pumps don’t have a long service life due to the properties of their material. Moreover, the cost is relatively high; personally, I think using water as the working fluid is more cost-effective
The domestic Kenfulei brand from Zibo, and the joint venture company Gitedinas (formerly Siemens) are also good options

The Gitedinas Company (formerly Siemens) is also unable to extract hydrochloric acid gas. The owner doesn’t require a high level of vacuum, so an RPP vacuum ejector will suffice. The economy is also cheap.
