Displacement per stroke was calculated at 4.8 

bar (70 psig) air inlet pressure against a 2.1 bar 

(30 psig) head pressure. 

Example:

 To pump 310 lpm (82 gpm) against 

a discharge head of 1.4 bar (20 psig) requires 
4.1 bar (60 psig) and 71 Nm

/h (42 scfm) air 

consumption. 

Flow rates indicated on chart were determined by pumping water. For optimum life and performance, pumps 
should be specified so that daily operation parameters will fall in the center of the pump's performance curve. 
 

Caution: Do not exceed 8.6 bar (125 psig) air supply pressure.
