Capacity curves
The performance curves are based on water at 20°C.Other circumstances might change the
performance. See below how the capacity will change at different viscosities and suction lifts.
Example:
A flow of 30 litre/minute is desired. The discharge pressure is calculated to 25 mWC. We
choose a T80 pump. It requires an air pressure of 4 bar and will consume approximately 0.20
Nm
3
of air per minute.
Recommended flow is half of the max flow, e.g. recommended flow for a T80 is 40 l/min.
