What are the differences between traditional peristaltic pump and innovative peristaltic pump?

Peristaltic pump I believe we are not unfamiliar with it, so do you understand the traditional peristaltic pump and innovative peristaltic pump what are the fundamental differences? I believe most of them are not so familiar with it. Please follow the small series of peristaltic pump to understand it.

The traditional peristaltic pump is a section of pump pipe between two rollers to form a pillow shaped fluid“ The volume of the "pillow" depends on the inner diameter of the pump pipe and the geometric characteristics of the rotor.

The flow rate depends on the product of the rotational speed of the pump head, the size of "pillow" and the number of "pillow" produced by each revolution of the rotor.

The innovative peristaltic pump is to squeeze the circular diaphragm in the pump body through the eccentric wheel, and the diaphragm is pushed forward by peristalsis in the cavity, so as to generate vacuum and medium flow.

The biggest advantage of this design is that the peristaltic pump pipe is canceled, the industry pain point is solved, and the maintenance is free forever.
