EXAMPLE
A PX800 polypropylene, Ultra-Flex-fi tted pump operating at EMS set-
ting 4, achieved a fl ow rate of 220 lpm (58 gpm) using 131 Nm3/h (77
scfm) of air when run at 6.9 bar (100 psig) air inlet pressure and 4.1
bar (60 psig) discharge pressure (See dot on performance curve).
The end user did not require that much fl ow and wanted to reduce
air consumption at his facility. He determined that EMS setting 3
would meet his needs. At 4.1 bar (60 psig) discharge pressure and
EMS setting 3, the fl ow “X factor” is 0.89 and the air “X factor” is
0.81 (see dots on EMS curve).
Multiplying the original setting 4 values by the “X factors” provides
the setting 3 fl ow rate of 195 lpm (52 gpm) and an air consumption
of 106 Nm3/h (62 scfm). The fl ow rate was reduced by 11% while
the air consumption was reduced by 19%, thus providing increased
effi ciency.
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 Effi ciency Management System (EMS)
can be used to optimize the performance of
your Wilden pump for specifi c applications.
The pump is delivered with the EMS adjusted
to setting 4, which allows maximum fl ow.
The EMS curve allows the pump user to deter-
mine fl ow 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
fl ow and air consumption values for that spe-
cifi c EMS setting. Note: you can interpolate
between the setting curves for operation at
intermediate EMS settings.
