What are the design requirements for vacuum pumps?
Thread Content
A new water-ring vacuum pump has been designed for use; is it appropriate to specify an inlet diameter of DN150 and an outlet diameter of DN100? Should a silencer be installed on the outlet? Are there any special requirements for installation?

Is it for venting? That’s not necessary; the pressure at the outlet of a vacuum pump isn’t high, so venting won’t produce much noise. There are no special requirements for installation – just follow the guidelines for centrifugal pumps. Agree with the person above; gas-liquid separation is key.
