For pumping to a vacuum tower, how should the pump outlet pressure be selected?
Thread Content
Hello, everyone! When calculating the pump for a vacuum tower, how should the pump outlet pressure be selected? I’ve encountered two types of engineering scenarios: 1) One involves normal operating pressure (vacuum); 2) The other involves atmospheric pressure, as water flushing is considered in this case (the vacuum system isn’t in use). May I ask, esteemed experts, how do you determine the outlet pressure in such cases? Thank you!

When a vacuum pump is in operation, what is the approximate pumping rate of the vacuum pump? Once these parameters are determined, I can give you suggestions!
