The Pro-Flo X™ air distribution system with the

revolutionary Effi ciency Management System (EMS)

offers fl exibility never before seen in the world of

AODD pumps. The

patent-pending EMS

is simple and easy

to use. With the

turn of an integrated

control dial, the operator can select the optimal

balance of fl ow and effi ciency that best meets the

application needs. Pro-Flo X™ provides higher

performance, lower

operational costs

and fl exibility that

exceeds previous

industry standards.

Pro-Flo XTM Operating Principal

S e c t i o n 5 B

Turning the dial changes the relationship between air inlet and exhaust porting.

Each dial setting represents an entirely different fl ow curve

Pro-Flo X™ pumps are shipped from the factory on setting 4, which is the highest fl ow rate setting possible

Moving the dial from setting 4 causes a decrease in fl ow and an even greater decrease in air consumption.

When the air consumption decreases more than the fl ow rate, effi ciency is improved and operating costs are reduced.

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 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 inlet pressure. Mark the point where this curve crosses the horizontal line representing 2.8 bar (40 psig) discharge pressure. (Figure 1). After locating your performance point on the fl ow curve, draw a vertical line downward until reaching the bottom scale on the chart. Identify the fl ow rate (in this case, 8.2 gpm). Observe location of performance point relative to air consump-tion curves and approximate air consumption value (in this case, 9.8 scfm).

Step 2: Determining flow and air X Factors. Locate your discharge pressure (40 psig) on the verti-cal axis of the EMS curve (Figure 2). Follow along the 2.8 bar (40 psig) horizontal line until intersecting both fl ow and air curves for your desired EMS setting (in this case, setting 2). Mark the points where the EMS curves inter-sect the horizontal discharge pressure line. After locating your EMS points on the EMS

curve, draw vertical lines downward until reaching the bottom scale on the chart. This identifi es the fl ow X Factor (in this case, 0.58) and air X Factor (in this case, 0.48).

Step 3: Calculating performance for specific EMS

setting. Multiply the fl ow rate (8.2 gpm) obtained in Step 1 by the fl ow X Factor multi-plier (0.58) in Step 2 to determine the fl ow rate at EMS setting 2. Multiply the air consump-tion (9.8 scfm) obtained in Step 1 by the air X Factor multiplier (0.48) in Step 2 to deter-mine the air consumption at EMS setting 2 (Figure 3).

Figure 3

The fl ow rate and air consumption at Setting 2 are found to be 18.2 lpm (4.8 gpm) and 7.9 Nm3/h (4.7 scfm) respectively.

EMS CURVESETTING 4 PERFORMANCE CURVE

This is an example showing how to determine the inlet air pressure and the EMS setting for your Pro-Flo X™ pump to optimize the pump for a specifi c application. 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.

Step 1: Establish inlet air pressure. Higher air pres-sures will typically allow the pump to run more effi ciently, however, available plant air pressure can vary greatly. If an operating pressure of 6.9 bar (100 psig) is chosen when plant air frequently dips to 6.2 bar (90 psig) pump performance will vary. Choose an oper-ating pressure that is within your compressed air system's capabilities. For this example we will choose 4.1 bar (60 psig).

Step 2: Determine performance point at setting 4. For this example an inlet air pressure of 4.1 bar (60 psig) inlet air pressure has been chosen. Locate the curve that represents the perfor-mance of the pump with 4.1 bar (60 psig) inlet air pressure. Mark the point where this curve crosses the horizontal line representing 2.8 bar (40 psig) discharge pressure. After locat-ing this point on the fl ow curve, draw a verti-cal line downward until reaching the bottom scale on the chart and identify the fl ow rate.

In our example it is 38.6 lpm (10.2 gpm). This is the setting 4 fl ow rate. Observe the loca-tion of the performance point relative to air consumption curves and approximate air consumption value. In our example setting 4 air consumption is 24 Nm3/h (14 scfm). See fi gure 4.

Step 3: Determine flow X Factor. Divide the required fl ow rate 18.9 lpm (5 gpm) by the setting 4 fl ow rate 38.6 lpm (10.2 gpm) to determine the fl ow X Factor for the application.

Step 4: Determine EMS setting from the flow

X Factor. Plot the point representing the fl ow X Factor (0.49) and the application discharge pressure 2.8 bar (40 psig) on the EMS curve. This is done by following the horizontal 2.8 bar (40 psig) psig discharge pressure line until it crosses the vertical 0.49 X Factor line. Typi-cally, this point lies between two fl ow EMS setting curves (in this case, the point lies be-tween the fl ow curves for EMS setting 1 and 2). Observe the location of the point relative to the two curves it lies between and approxi-mate the EMS setting (fi gure 5). For more pre-cise results you can mathematically interpo-late between the two curves to determine the optimal EMS setting.

5 gpm / 10.2 gpm = 0.49 (flow X Factor)

DETERMINE EMS SETTING

For this example the EMS setting is 1.8.

EMS CURVESETTING 4 PERFORMANCE CURVE

Example 2.2

Determine air consumption at a specific

EMS setting.

Step 1: Determine air X Factor. In order to determine the air X Factor, identify the two air EMS set-ting curves closest to the EMS setting estab-lished in example 2.1 (in this case, the point lies between the air curves for EMS setting 1 and 2). The point representing your EMS setting (1.8) must be approximated and plotted on the EMS curve along the horizontal line represent-ing your discharge pressure (in this case, 40 psig). This air point is different than the fl ow point plotted in example 2.1. After estimating (or interpolating) this point on the curve, draw a vertical line downward until reaching the bottom scale on the chart and identify the air X Factor (fi gure 7).

Step 2: Determine air consumption. 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 Nm3/h (5.6 scfm) of compressed air.

For this example the air X Factor is 0.40
