EXAMPLE
A PX15 aluminum, Ultra-Flex-fi
tted pump operating at EMS setting 4,
achieved a fl
ow rate of 719 lpm (190 gpm) using 255 Nm
3
/h (150 scfm)
of air when run at 6.9 bar (100 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 1
would meet his needs. At 0.7 bar (10 psig) discharge pressure and EMS setting 1, the fl
ow “X factor” is 0.48 and the air “X factor” is
0.22 (see dots on EMS curve). Multiplying the original setting 4 values by the “X factors” provides the setting 1 fl
ow rate of 345 lpm (91 gpm) and an air consumption
of 56 Nm
3
/h (33 scfm). The fl
ow rate was reduced by 52% while the
air consumption was reduced by 78%, thus providing increased ef- fi 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.

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.
