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.

..................2.1 L (0.55 gal)
Max. Flow Rate ............ 645 lpm (171 gpm)
Max. Size Solids ....................6.4 mm (1/4”)

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 416 lpm (110 gpm)
against a discharge head of 2.1 bar
(30 psig) requires 5.5 bar (80 psig) and
102 Nm
3
/h (60 scfm) air consumption.
Caution: Do not exceed 6.9 bar (100 psig)
air supply pressure.
