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.

............ 4.9 L (1.30 gal) AL
5.0 L (1.32 gal) SS
Max. Flow Rate ............ 992 lpm (262 gpm)

1
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 420 lpm (111 gpm)
against a discharge head of 2.8 bar (40
psig) requires 4.8 bar (70 psig) and 110
Nm
3
/h (65 scfm) air consumption.
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.

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 360 lpm (95 gpm)
against a discharge head of 3.4 bar (50
psig) requires 5.5 bar (80 psig) and 118
Nm
3
/h (75 scfm) air consumption.
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.
