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

EXAMPLE
A PX220/PX230 metal, TPE-fitted pump operating at EMS setting 4 achieved a flow rate of 142 lpm (38 gpm) using 49 Nm
3
/h (29 scfm)
of air when run at 4.1 bar (60 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 1
would meet his needs. At 1.4 bar (20 psig) discharge pressure and EMS setting 1, the flow X factor is 0.18 and the air X factor is 0.07 (see dots on EMS curve). Multiplying the original setting 4 values by the X factors provides the setting 1 flow rate of 26 lpm (7 gpm) and an air consumption of 3 Nm
3
/h (2 scfm). The flow rate was reduced by 82% while the
air consumption was reduced by 93%, thus providing increased efficiency
.
For a detailed example for how to set your EMS, see beginning of perfor
-
mance curve section. Caution: Do not exceed 8.6 bar (125 psig) air supply pressure. Canadian Standards Association (CSA) configured pumps should
not exceed 6.9
bar (100 psig) natural gas supply pressure. Please read all cautions and suggested installation sections before operating any Wilden product.
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 determine 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 performance curve to calculate the actual flow and air consumption values for that
specific
EMS
setting.
NOTE:
Y
ou
can
interpolate
between
the
setting
curves
for
operation at intermediate EMS settings.
