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 45.4 lpm (12.0 gpm)
against a discharge pressure head of 2.7 bar
(40 psig) requires 4.1 bar (60 psig) and 22.1

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

SUCTION LIFT CURVE
Suction lift curves are calibrated for pumps operating at 305 m
(1,000') above sea level. This chart is meant to be a guide only.

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 performance curve.

elbows, viscosity of pumping fluid, elevation (atmospheric
pressure) and pipe friction loss all affect the amount of suction
lift your pump will attain.
