How to match a booster pump with a primary pump
Thread Content
Hello, teachers! When the operating vacuum level of the user is 0.7 mbara, how should the pre-pump and the booster pump be configured, and what is the ratio? I hope the teacher can give an example. Thank you
A Roots pump combined with a screw pump: a 600 L/S Roots pump paired with a 150 L/S screw pump. The pumping speed ratio is equal to the compression ratio of 4:1
Is the 70 Pa vacuum requirement for the pump inlet or for the customer’s reactor? If the pump inlet requires a Roots screw unit with a compression ratio of 1:4, then for the requirements at the reactor inlet, it may be necessary to use a combination of Roots + Roots + screw
