hello, I'm a final year student doing my graduation thesis, I have a content about aspirating passion fruit juice with a vacuum pump, but I choose the peristaltic pump to do this content. But when reading the number of articles about peristaltic pumps, I see that there are limitations on the inlet suction speed and the flow in the tube is quite low while the flow I want must be above 250 l/h. Hope everyone can point out if I'm on the right track or if there are other better solutions. Thank you for taking the time to read this post

Attaching a simple PFD showing elevations would help us help you.

Peristaltic pumps rely on the elastic return of a flattened rubber tube to a round cross-sectional shape. The amount of suction pressure it can generate falls rapidly as tubing diameter increases. So it is a poor choice for your application, where you must pump large chunks. There a a variety of types of pumps that can work, but they must be particularly designed to handle large chunks of material gently. Sanitary design is also a requirement for food service.

Really, a requirement for food service got me in trouble. Because I'm a mechanical engineer who designed a machine to suck the juice of passion fruit from the original raw fruit, the research about the pump can suck the passion fruit pulp including seeds and passion fruit juice. The amount of liquid that includes solids, I only find the peristaltic pump to be effective in my opinion. The diameter of the suction pipe is about 12.7 mm - 25.4 mm

So, how many 12.7 or 25.4 (or 19) mm peristaltic pumps working in parallel is needed for > 250 l/hr? My guess is, it’s not a large, impractical number of pumps. Maybe 1-3 pumps depending on size? Tell us.

Good Luck,

A peristaltic pump can easily be designed to drive dozens of tubes at once. However, there are other types of pumps that would be more suitable, like progressive cavity pumps, air operated double diaphragm pumps, or even a vacuum conveyor.

Well, I found a method to take advantage of the suction of the vacuum pump to suck the liquid. But I don't know the name of this method to have reading and calculation documentation for the method. Some pictures I found on youtube.The title of the video is "Vacuum pump (liquid suction)".Really , thank you for paying attention to my posts in the past time . Those are good tips for me
