I bought a slightly used jebao dp-4 dosing pump and I have some questions about how it's supposed to run or the pump head assembly:
1. Is the solution supposed to stay in the line after it's perged? After running the pump and removing any air in the lines the solution would slowly drain back through the line.
2. Calibration past maximum 250? When I calibrated each pump, almost all 4 wouldn't even finish pumping the full 100ml before it hit 250 revolutions.
I've been researching this dosing pump and one problem I found was how the peristaltic pump was assembled: does anyone know how the rollers are supposed to be installed correctly?
