Dimensioning criterias
The top four criteria are:
WHAT for a medium? –> Pumping medium
HOW MUCH Amount? –> Flow rate
WHERE, how far, how high? –> Pipe geometry
WHICH pump unit should be used? –> Delivery unit
If the flow rate and pipe geometry are known, the head can be calculated with the help of the pressure loss calculation. Flow rate and head together form the duty point for the pump design.
