SETTING 4 PERFORMANCE CURVE EMS CURVE Figure 1Figure 2 Example data point = Example data point = > This is an example showing how to determine fl ow rate and air consumption for your Pro-Flo X pump using the Effi cien-cy Management System (EMS) curve and the performance curve. For this example we will be using 4.1 bar (60 psig) inlet air pressure and 2.8 bar (40 psig) discharge pressure and EMS setting 2. Step 3: Calculating performance for specific EMS setting. Step 1: Identifying performance at setting 4. Locate the curve that represents the fl ow rate of the pump with 4.1 bar (60 psig) air...

For this exam-ple we will be using an application requirement of 18.9 lpm (5 gpm) fl ow rate against 2.8 bar (40 psig) discharge pressure. This example will illustrate how to calculate the air consump- tion that could be expected at this operational point. 3 /h (14 scfm). See fi gure 4. > Step 1 : Establish inlet air...

Multiply your setting 4 air consumption (14 scfm) value by the air X Factor obtained above (0.40) to deter- mine your actual air consumption.In summary, for an application requiring 18.9 lpm (5 gpm) against 2.8 bar (40 psig) discharge pressure, the pump inlet air pressure should be set to 4.1 bar (60 psig) and the EMS dial should be set to 1.8. The pump would then consume 9.5 Nm Step 1 : Determine air X Factor. In order to determine...

He determined that EMS setting 1 would meet his needs. At 2.8 bar (40 psig) discharge pressure and EMS setting 1, the fl ow X factorӔ is 0.33 and the air X factorӔ is 0.24 (see dots on EMS curve). Multiplying the original setting 4 values by the X factorsӔ provides the setting 1 fl ow rate of 82 lpm (22 gpm) and an air consumption of 24 Nm 3 EMS CURVE /h (14...

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 factorӔ is 0.74 and the air X factorӔ is 0.51 (see dots on EMS curve). Multiplying the original setting 4 values by the X factorsӔ provides the setting 2 fl ow rate of 244 lpm (64 gpm) and an air consumption of 62 Nm 3 EMS CURVE /h (36...

He determined that EMS setting 3 would meet his needs. At 2.1 bar (30 psig) discharge pressure and EMS setting 3, the fl ow X factorӔ is 0.87 and the air X factorӔ is 0.78 (see dots on EMS curve). Multiplying the original setting 4 values by the X factorsӔ provides the setting 3 fl ow rate of 158 lpm (42 gpm) and an air consumption of 74 Nm 3 EMS CURVE /h (44...
