Water ring vacuum pump
Thread Content
The water ring vacuum pumps in our factory are suffering from severe corrosion; a pump casing made of ordinary carbon steel can last at most half a year. The fluids being pumped are aromatic oils and industrial crude naphthalene. Is there any way to prevent corrosion?
When this happens, the erosion effect also needs to be taken into consideration. Is your water ring vacuum pump connected directly to the working fluid? In that case, it is necessary to consider adding a condenser to reduce the amount of condensable vapor that enters the pump.
It is possible to consider switching to a stainless-steel water ring pump.
It’s probably caused by cavitation; consider that aspect
Consider adding preservatives and using equipment materials of a higher grade
Stainless steel versions are available for purchase. The results will be much better
