No an overview valves are needed.

Peristaltic pumps Suitable applications can operate dry without risk. Peristaltic pumping is ideal for most fluids, including How they work viscous, shear-sensitive, corrosive and abrasive flu- ids, and those containing suspended solids.

They are particularly suitable for ating a partial vacuum which is filled by fluid drawn metering, dosing and dispensing applications. from the inlet port. Pumps are easy to install, simple to operate and inexpensive to maintain. Before the roller reaches the end of the track, a sec- ond roller compresses the tube at the start of the track, isolating a packet of fluid between the com- pression points. As the first roller leaves the track, the second continues to advance, expelling the packet of fluid through the pump’s discharge port. At the same time, a new partial vacuum is created behind the second roller into which more fluid is drawn from the inlet port.
