Hi All,
How to find vacuum created or suction created when we use peristaltic pump?

Hi,sophiecentaur said:Hi and welcome.
If you want an answer to this then we need to know a bit more context for your question, I think. I would just make the point that there is strictly no such thing as 'suck'. Fluids move because of excess pressure on one side, which pushes them. A peristaltic pump has an essentially 'floppy' tube which is squeezed (a positive pressure is applied) in parts to force a fluid along it. If the fluid in the tube is squeezed along the tube and the tube is then collapsed, then new fluid would only be forced in by the pressure difference in the upstream reservoir and the inside of the floppy tube. It the tube has walls that naturally (passively) spring back to shape, then you might expect a small pressure difference. A vacuum pump provides a force from a piston to produce a very low pressure in the pump - lower than the pressure in the evacuated reservoir.
A peristaltic pump is a type of positive displacement pump that uses a series of rollers or gears to compress and expand a flexible tube, creating a vacuum or suction effect to move fluids through the pump.
A vacuum is created in a peristaltic pump by the compression and expansion of the flexible tube as it is squeezed and released by the rotating rollers or gears. This action creates a suction effect that pulls the fluid through the pump.
Peristaltic pumps offer several advantages, including gentle handling of delicate fluids, high accuracy and precision, self-priming capabilities, and the ability to handle a wide range of viscosities and corrosive substances.
Yes, peristaltic pumps are commonly used in vacuum or suction systems, as they are able to create a strong vacuum or suction effect to move fluids without causing damage or contamination.
A peristaltic pump differs from other types of pumps in that it uses a flexible tube to compress and expand, rather than impellers or pistons. This makes it suitable for handling sensitive fluids and allows for easy cleaning and maintenance.
