EXAMPLE
A PX400 metal, TPE-fitted pump operating at EMS setting 4, achieved
a
flow
rate
of
204
lpm
(54
gpm)
using
90
Nm

/h
(53
scfm)
of
air
when run
at
5.5
bar (80
psig)
air
inlet
pressure
and
2.1
bar
(30
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 1
would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS
setting
1,
the
flow
X
factor
is
0.44
and
the
air
X
factor
is
0.24
(see dots on EMS curve). Multiplying the original setting 4 values by the X factors provides the setting 1 flow rate of 90 lpm (24 gpm) and an air consumption of 22 Nm
3
/h (13 scfm). The flow rate was reduced by 13% while
the air consumption was reduced by 48%, thus providing increased efficiency
.
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
.
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 PX400 metal, TPE-fitted pump operating at EMS setting 4, achieved a flow rate of 227 lpm (60 gpm) using 90 Nm
3
/h (53 scfm) of air when
run at 4.6 bar (67 psig) air inlet pressure and 2.1 bar (30 psig) dis
-
charge 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 1
would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS setting 1, the flow “X factor” is 0.38 and the air “X factor” is 0.23 (see dots on EMS curve). Multiplying the original setting 4 values by the “X factors” provides the setting 1 flow rate of 86 lpm (23 gpm) and an air consumption of 21 Nm
3
/h (12 scfm). The flow rate was reduced by 62% while
the air consumption was reduced by 77%, thus providing increased efficiency
