Selection of Roots vacuum pumps
Thread Content
I would like to ask the experts: which manufacturer’s Roots vacuum pump is the best for distilling 3-mercaptopropionic acid? Thank you
They’re more or less the same; the quality of Shanghai Kaini is slightly more stable, but whether it’s useful depends mainly on the system design! ——This is key!
Rotary vane pumps cannot be used alone; they need to be paired with a pre-stage pump to form a unit, so unit design is very important.
Hello, the pumping speed of the primary pump is 320 cubic feet per hour, while that of the Roots pump is 150 liters per second. What is its ultimate vacuum level?
