The Effi

 ciency Management System (EMS) 

can be used to optimize the performance of 

your Wilden pump for specifi

 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. 

EXAMPLE

A PX15 aluminum, Full Flow PTFE fi

 tted pump operating at EMS set-

ting 4, achieved a fl

 ow rate of 681 lpm (180 gpm) using 209 Nm3/h (123 

scfm) of air when run at 5.5 bar (80 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 fl

 ow and wanted to reduce 

air consumption at his facility

.  He determined that EMS setting 2 

would meet his needs.  At 1.4 bar (20 psig) discharge pressure and 

EMS setting 2, the fl

 ow “X factor” is 0.73 and the air “X factor” is 

0.59 (see dots on EMS curve).  

Multiplying the original setting 4 values by the “X factors” provides 

the setting 2 fl

 ow rate of 497 lpm (131 gpm) and an air consumption 

of 123 Nm3/h (73 scfm).  The fl

 ow rate was reduced by 27% while 

the air consumption was reduced by 41%, thus providing increased 

effi

 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.
