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: Mushroom check valve = 88%. For optimum
life
and performance, pumps should be specified so that daily operation parameters fall in the center of the pump's performance curve

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.
NOTE:
Y
ou can
interpolate be
-
tween the setting curves for operation at in
-
termediate EMS settings.
EXAMPLE
A PX15 Saniflo HS, reduced-stroke SIPD-fitted pump operating at EMS setting 4, achieved a flow rate of 246 lpm (65 gpm) using 102 Nm
3
/h (60 scfm) of air when run at 4.1 bar (60 psig) air inlet pressure
and
2.1
bar
(30
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 2
would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS
setting
2,
the
flow
X
factor
is
0.71
and
the
air
X
factor
is
0.51
(see dots on EMS curve). Multiplying the original setting 4 values by the X factors provides the setting
2
flow
rate
of
175
lpm
(46
gpm)
and
an
air
consumption
of
52
Nm
3
/h (31 scfm). The flow rate was reduced by 29% while the air con
-
sumption was reduced by 49%, thus providing increased efficiency
.
