– How do I choose the right nominal diameter for the pump?

1) Determine the delivery capacity (l/min) required and the pump height or counter-pressure
(Example: 50 l/min, pump height or counter-pressure 4.0 bar)

2) The compressed air volume and compressed air demand can be read from the pump curve
(Example: 0.38 Nm3/min at 6.0 bar)
