Displacement per stroke was calculated at 4.8 bar (70 psig)
air inlet pressure against a 2 bar (30 psig) head pressure.
The Efficiency Management System (EMS)
can be used to optimize the performance of your Wilden pump for specific applications.
The pump is delivered with the EMS adjusted to setting 4, which allows maximum flow
.
The
EMS
curve
allows
the
pump
user to
deter
-
mine flow and air consumption at each EMS setting. For any EMS setting and discharge pressure, the X factor is used as a multiplier with the original values from the setting 4 per
-
formance curve to calculate the actual flow and air consumption values for that specific EMS setting.
NOTE: Y
ou can
interpolate be
-
tween the setting curves for operation at in
-
termediate EMS settings.
EXAMPLE
A PX8 metal, reduced-stroke PTFE-fitted pump operating at EMS setting 4, achieved a flow rate of 401 lpm (106 gpm) using 133 Nm
3
/h
(78 scfm) of air when run at 4.8 bar (70 psig) air inlet pressure and 1.4 bar (20 psig) discharge pressure (see dot on performance curve).
The end user did not require that much flow and wanted to reduce air consumption at his facility
. He determined that EMS setting 3
would meet his needs. At 1.4 bar (20 psig) discharge pressure and EMS
setting
3,
the
flow
X
factor
is
0.82
and
the
air
X
factor
is
0.70
(see dots on EMS curve).
Multiplying the original setting 4 values by the X factors provides the setting 3 flow rate of 329 lpm (87 gpm) and an air consumption of
93
Nm
3
/h
(55
scfm).
The
flow
rate
was
reduced by
18%
while
the
air consumption was reduced by 30%, thus providing increased ef
-
ficiency
.
For a detailed example for how to set your EMS, see beginning of performance curve section.
CAUTION: Do not exceed 8.6 bar (125 psig) air supply pressure.
