Dimensioning criterias

The dimensioning of pumps and pressure pipelines must be carried out step by step.

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.

Density

The density is an important fluid property that depends on the temperature. The density of the pumped medium has a direct influence on the power requirement of the pump.

Pump Performance Curve

The pumping performance of a centrifugal pump is expressed in the form of an H-Q curve, depicting the Flow Q (e.g. in m³/h) and the Head H (e.g. in m) of the pump.
