What vacuum pump is suitable for synthetic reaction vessels?
Thread Content
Hello everyone, for a 1-ton polyester reactor, vacuum pumping is required in the final stage of synthesis to increase the degree of esterification. What type of vacuum pump would be suitable?
Multiple pieces of information, such as vacuum level requirements and whether the medium is corrosive or not.
A Schich water ring vacuum pump will do.
With such a small volume, a water jet pump is inexpensive and reliable.
A water jet pump is sufficient if the vacuum level requirements are not high; for higher requirements, a Roots pump should be used
Water ring vacuum pumps seem to be quite useful
The medium is basically non-corrosive; its main function is to remove the small amount of water vapor produced by the reaction
Thank you for getting back to me. Do you have any good manufacturers to recommend? {:2_30:}
Hello, do you have any recommendations for good manufacturers or models? Also, is it necessary to install a drying device in front of the vacuum pump to protect it from moisture?
Add a gas-liquid separator; jet pumps are quite useful
A small liquid ring vacuum pump works very well.
