Peristaltic Pump Suction Lift Limit

There are many applications of peristaltic pumps, most of which are used for the transport of liquids. If the distance of transmission is not at the same level, there is no loss, but if you extract water from a lower place from a higher place, you need to Consider the peristaltic pump suction lift limit.

Why consider a peristaltic pump suction lift limit? We all know that a peristaltic pump is a kind of precision instrument. It is used to transmit liquids with a certain precision. If the height of the transmission is very large, it may cause a certain loss to the liquid to be transported. We have tested and used an ordinary OEM peristaltic pump to suck water from a distance of 15 meters upstairs. The flow rate can reach about 80% of the horizontal transmission, which means that there will be a 20% loss.

Of course, different peristaltic pump models use different motors, plus some different components, their suction strokes are also different. In a short distance, there is generally no loss. If the distance is long, it should be tested according to the actual situation.

In many cases, the peristaltic pump and the liquid to be transported are not in direct contact. If the excitation is very long, contact the peristaltic pump manufacturer as much as possible to ask for a suction stroke or a lift limit to ensure a certain accuracy of the liquid.
