Flow rates indicated on chart were determined by pumping water with a vertically-mounted, center
-ported ball check
configuration. 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 determine 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 performance curve to calculate the actual flow and air consumption values for that
specific
EMS
setting.
NOTE:
Y
ou
can
interpolate
between
the
setting
curves
for
operation at intermediate EMS settings.
EXAMPLE
A PX15 Saniflo HS, reduced-stroke PTFE-fitted pump operating at EMS setting 4, achieved a flow rate of 522 lpm (138 gpm) using 160 Nm
3
/h (94 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 flow 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
flow
X
factor
is
0.33
and
the
air
X
factor
is
0.17
(see dots on EMS curve). Multiplying
the original
setting
4 values by the
X
factors
provides
the
setting 1 flow rate of 172 lpm (46 gpm) and an air consumption of 27 Nm
3
/h (16 scfm). The flow rate was reduced by 67% while the air con
-
sumption was reduced by 83%, thus providing increased efficiency
.
