How to Read the Diaphragm Pump Curves

Examples:

TR9 (see dotted red line):
A flow of 6 L/min is desired. The discharge head is calculated to 30 mWC. We choose a TR9. It requires an air pressure of 6 bar and will consume approximately 0.10 Nm3 air per minute.

 

 

 

 

 

T25 curve exampleT25 (see dotted red line):
A flow of 10 L/min is desired. The discharge head is calculated to 20 mWC. We choose a T25. It requires an air pressure of 4 bar and will consume approximately 0.10 Nm3 air per minute.
