The diaphragm pump has unstable flow rate
Thread Content
When a diaphragm pump switches to its backup unit, it often experiences insufficient flow or no flow at all. Have you encountered this issue? How can it be resolved?
It should be that there’s some air in the system or particles in the medium; just vent it out
Agree with what was said above; we don’t bother with this here either – the inlet and outlet valves are just left open.
