I am trying to work our it it is worth while buying a Variable speed pump (viron p320) with the below flow curve.
I have 9.5 meters of piping from the skimmer to the pump, and about 8.5m from filter to second outlet point. (about 18m of total piping alone). Does the below curve suggest I need to run on high - achieve a low rate of 100L per minute? Am I reading it right?
If this is the case - it is not worth while me buying this pump - as I will need to run it on high to get a decent flow.
Does the total head axis on these diagrams refer to total pipes of just pipes from skimmer to pump?
