Flow rates indicated on chart were determined by pumping water with a vertically-mounted, center
-ported ball check configuration.
When alternate check valve options are used, multiply flow rate by appropriate factor: Flap check valve = 86%. For optimum life
and
performance, pumps should be specified so that daily operation parameters fall in the center of the pump's performance curve.
EXAMPLE
A PX15 Saniflo HS, full stroke TPE-fitted pump operating at EMS set
-
ting 4, achieved a flow rate of 488 lpm (129 gpm) using 109 Nm
3
/h (64
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 3
would meet his needs. At 1.4 bar (20 psig) discharge pressure and EMS
setting
3,
the
flow
X
factor
is
0.88
and
the
air
X
factor
is
0.73
(see dots on EMS curve). Multiplying the original setting 4 values by the X factors provides the setting 3 flow rate of 430 lpm (114 gpm) and an air consumption of 79 Nm
3
/h (47 scfm). The flow rate was reduced by 12% while
the air consumption was reduced by 27%, 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.

Displacement per stroke was calculated at 4.8 bar (70 psig) air inlet pressure against a 2.1 bar (30 psig) head pressure.
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.
