How to effectively prevent corrosive media from affecting vacuum pumps
Thread Content
Regarding highly corrosive substances such as hydrochloric acid, bromides, and fluorides encountered in industrial production processes, apart from using steam jet vacuum pumps, are there any other good recommendations for selecting vacuum pumps?
Among liquid ring vacuum pumps, the steam jet pump is the one that has more developed solutions for dealing with corrosive media. With increasingly strict environmental regulations, the problems related to wastewater and exhaust gas emissions, which are inevitable for various liquid ring vacuum pumps, have become more prominent. Recently, many customers have been asking how dry vacuum pumps can effectively handle highly corrosive substances such as hydrochloric acid and hydrofluoric acid. We have some experience and insights in this regard, and we would like to share them with everyone for discussion. . .
Using water ring pumps made entirely of non-metallic materials creates a closed-loop system that is resistant to corrosion and environmentally friendly; we have handled many cases involving hydrochloric acid applications.
After purchasing the vacuum pump, the user should carry out pre-protection again on their own.
Given the increasing pressure to protect the environment, it is recommended to choose dry vacuum pumps, such as screw or claw type pumps, as they provide a higher level of vacuum. For corrosion resistance, careful selection is necessary; in the case of hydrochloric acid, things become even more complex! It’s necessary to understand the specific operating conditions before anything can be said
