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 stainless steel, reduced-stroke PTFE-fitted pump operating at EMS setting 4, achieved a flow rate of 204 lpm (54 gpm) using 133 Nm
3
/h
(78 scfm) of air when run at 5.5 bar (80 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
0.70
and
the
air
X
factor
is
0.47
(see dots on EMS curve). Multiplying the original setting 4 values by the X factors provides the setting 3 flow rate of 143 lpm (38 gpm) and an air consumption of 62 Nm
3
/h (37 scfm). The flow rate was reduced by 30% while
the air consumption was reduced by 53%, 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 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 multi
-
plier with the original values from the setting 4 performance curve to calculate the actual flow and air consumption values for that spe
-
cific EMS setting. Note: you can interpolate between the setting curves for operation at intermediate EMS settings.
EXAMPLE
A PX400 metal, PTFE-fitted pump operating at EMS setting 4, achieved a flow rate of 170 lpm (45 gpm) using 85 Nm
3
/h (50 scfm)
of air
when
run at 3.6 bar
(52 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 3
would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS setting 3, the flow “X factor” is 0.88 and the air “X factor” is 0.76 (see dots on EMS curve). Multiplying the original setting 4 values by the “X factors” provides the setting 3 flow rate of 150 lpm (40 gpm) and an air consumption of 65 Nm
3
/h (38 scfm). The flow rate was reduced by 12% while
the air consumption was reduced by 24%, thus providing increased efficiency
