To find Fluid Outlet Pressure
(bar/psi) at a specific fluid flow (lpm/gpm)
and operating air pressure (bar/psi):
1. Locate desired flow along bottom of chart.
2. Follow vertical line up to intersection with selected fluid outlet pres-
sure curve (black). Follow left to scale and read fluid outlet pressure.
To find Pump Air Consumption
(m
#
/min or scfm) at a specific fluid flow
(lpm/gpm) and fluid pressure (bar/psi):
1. Locate desired flow and pressure on chart.
2. Interpolate air consumption, noting gray lines of constant air con-
sumption.
This pump was tested in water, with a
diaphragm
and the inlet submerged. For conditions different from this, reduce the
flow as follows.
