Seeking help with a pump issue

During the vacuum distillation of oil, the choice of pump at the bottom of the tower: What type of pump should be selected? Operating conditions: oil washing + diesel separation, vacuum of 200 Pa (absolute pressure), temperature of 150°C, flow rate of approximately 15 m3/h.

Best choice: screw vacuum pump + Roots pump……

The vacuum at the upper level is provided by a Roots pump + another Roots pump + a liquid ring pump. As for the pump to be used for oil transfer at the lower level, what type of pump should be chosen, given that it needs to operate continuously?

Centrifugal pump or screw pump with liquid-inlet turbocharging for material transfer

Practice has shown that centrifugal pumps are the best choice; screw pumps are not as effective as centrifugal pumps.

Personally, I think centrifugal pumps are more useful. If you need information on centrifugal pumps or guidelines for their use, etc., I can provide that to you.

Use centrifugal pumps whenever possible; consult the manufacturer to determine whether they are suitable. Practice has shown that centrifugal pumps are quite durable; it makes sense that most centrifugal pumps are used in chemical processing applications

Centrifugal pumps are indeed useful and easy to maintain; it’s worth contacting a few manufacturers to compare them based on the operating conditions

Hello, OP! A high-vacuum discharge pump can be used, allowing normal discharge at a vacuum level of 5 Pa. Feel free to leave me a message at any time; we can learn from each other*.
