Displacement per stroke was calculated at 4.8 bar (70 psig)
air inlet pressure against a 2.1 bar (30 psig)head 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
determine fl ow 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 fl ow and air consumption values
for that specifi c EMS setting. Note: you can
interpolate between the setting curves for
operation at intermediate EMS settings.
EXAMPLE
A PX800 polypropylene, reduced stroke PTFE-fi tted pump operating
at EMS setting 4, achieved a fl ow rate of 439 lpm (116 gpm) using 146
Nm
3
/h (86 scfm) of air when run at 5.5 bar (80 psig) air inlet pressure and
0.7 bar (10 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 2
would meet his needs. At 0.7 bar (10 psig) discharge pressure and
EMS setting 2, the fl ow “X factor” is 0.67 and the air “X factor” is
0.46 (see dots on EMS curve).
Multiplying the original setting 4 values by the “X factors” provides
the setting 2 fl ow rate of 294 lpm (78 gpm) and an air consumption
of 67 Nm
3
/h (40 scfm). The fl ow rate was reduced by 33% while the
air consumption was reduced by 54%, 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.
