The liquid ring vacuum pump has been in use for a year and a half, and the pump casing is in this condition
Thread Content
There are two liquid ring vacuum pumps, one in operation and one as a backup. The two pumps have been in use for one and a half years, and one of them has developed leaks. Upon disassembly, it turned out to be in such poor condition – it’s hard to believe that the pump casing could get worn down to this extent. Could anyone help analyze what might be the cause?
Impressive. It is usually sand erosion corrosion, medium corrosion, or cavitation; it’s normal.

It seems that medium corrosion and cavitation are quite severe
It seems the pump casing material needs to be upgraded; let’s consider Hastelloy.
1. Use materials resistant to cavitation； 2. Modify the pipe structure to increase the net positive suction head ； 3. Install a filter in front to remove impurities.
The medium is not corroded; it’s just that the vacuum level is a bit high. Cavitation and material issues need to be considered

Your liquid ring vacuum pump is a distributor, not a distribution disk. This type of vacuum pump has a limited suction range, and the corrosion (erosion) is quite severe. Firstly, it’s likely that the medium in question dissolves easily in water, resulting in corrosive effects; secondly, there is cavitation~
Shouldn’t a water ring vacuum pump have an erosion line?
