Displacement per stroke was calculated
at 4.8 bar (70 psig) air inlet pressure against
a 2 bar (30 psig) head pressure.
Example: To pump 8.7 lpm (2.3 gpm)
against a discharge pressure head of
2 bar (30 psig) requires 4.1 bar (60 psig)
and 2.4 Nm

/h (1.4 scfm) air consumption.
(See dot on chart.)
Caution: Do not exceed 8.6 bar (125 psig)
air supply press.
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.
