1 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 1212 lpm (32 gpm)
against a discharge head of 2.8 bar
(40 psig) requires 4.2 bar (60 psig)
and 48 Nm 3 /h (28 scfm) air consumption.
Caution: Do not exceed 8.6 bar (125 psig)
air supply pressure.
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.
