EXAMPLE

A PX400 metal, TPE-fitted pump operating at EMS setting 4,  achieved 

a 

flow 

rate 

of 

204 

lpm 

(54 

gpm) 

using 

90 

Nm

3

/h 

(53 

scfm) 

of 

air 

when run 

at 

5.5 

bar (80 

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 1 

would meet his needs.  At 2.1 bar (30 psig) discharge pressure and  EMS 

setting 

1, 

the 

flow 

X 

factor 

is 

0.44 

and 

the 

air 

X 

factor 

is 

0.24 

(see dots on EMS curve).  

Multiplying the original setting 4 values by the X factors provides  the setting 1 flow rate of 90 lpm (24 gpm) and an air consumption  of 22 Nm

3

/h  (13 scfm).  The flow rate was reduced by 13% while 

the air consumption was reduced by 48%, 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

.

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 PX400 metal, TPE-fitted pump operating at EMS setting 4, achieved  a flow rate of 227 lpm (60 gpm) using 90 Nm

3

/h (53 scfm) of air when 

run at 4.6 bar (67 psig) air inlet pressure and 2.1 bar (30 psig) dis

-

charge 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 2.1 bar (30 psig) discharge pressure and  EMS setting 1, the flow “X factor” is 0.38 and the air “X factor” is  0.23 (see dots on EMS curve).  

Multiplying the original setting 4 values by the “X factors” provides  the setting 1 flow rate of 86 lpm (23 gpm) and an air consumption  of 21 Nm

3

/h  (12 scfm).  The flow rate was reduced by 62% while 

the air consumption was reduced by 77%, thus providing increased  efficiency
