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 PX800 polypropylene, rubber-fi tted pump operating at EMS set- ting 4, achieved a fl ow rate of 303 lpm (80 gpm) using 88 Nm3/h (52 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 fl ow and wanted to reduce air consumption at his facility. He determined that EMS setting 1 would meet his needs. At 1.4 bar (20 psig) discharge pressure and EMS setting 1, the fl ow “X factor” is 0.28 and the air “X factor” is 0.19 (see dots on EMS curve). Multiplying the original setting 4 values by the “X factors” provides the setting 1 fl ow rate of 85 lpm (22 gpm) and an air consumption of 17 Nm3/h (10 scfm). The fl ow rate was reduced by 72% while the air consumption was reduced by 81%, 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.
