RE: Peristaltic pumps
A water-like product with the tank above the pump, producing 5 psi discharge with new hose running around the middle of speed curve should be quite consistent.
A 5000 Cps product, 5ft below the pump, running at full speed with 40 psi discharge is a different story.

RE: Peristaltic pumps
8 bar is pretty high for many peristaltics (depending on design). Most of the pumps I work with are rated less than 3 bar for this size pump.
If the output pressure stays consistent, you should have good repeatability. Hose life at higher pressures will be the downfall. You will probably want to replace them regularily.
RE: Peristaltic pumps
An investigation we did shows that the repeatability of flowrate is not very satisfactory. After a period of use, the hose will not bounce back to the original shape, so it is necessory to re-calibrate it or replace the hose before it blows off if you require certain accuracy. Try talk to the vendor for the accuracy you want.
RE: Peristaltic pumps
Do you have a pump that can do 8 bar with this hose?
