Product catalog summary

Introduction
The document details the Pro-Flo X™ air distribution system, which incorporates the Efficiency Management System (EMS) for Air-Operated Double-Diaphragm (AODD) pumps. This system enables operators to adjust the balance between flow and efficiency using a control dial, thereby enhancing performance and reducing operational costs.

Operating Principle
The Pro-Flo X™ system functions by adjusting a dial to modify the relationship between air inlet and exhaust porting. The default factory setting is 4, which provides the highest flow rate. Adjusting the dial decreases flow and air consumption, thereby improving efficiency.

Using the EMS Curve
The document includes a step-by-step guide on using the EMS curve to determine flow rate and air consumption, with examples illustrating specific settings and pressures.

Example Calculations
1. For a flow rate of 18.9 lpm (5 gpm) against a 2.8 bar (40 psig) discharge pressure, the inlet air pressure should be set to 4.1 bar (60 psig) with an EMS setting of 1.8, resulting in an air consumption of 9.5 Nm3/h (5.6 scfm).
2. Another example shows a pump operating at EMS setting 4 achieving a flow rate of 250 lpm (66 gpm) using 102 Nm3/h (60 scfm) of air. By adjusting to EMS setting 1, the flow rate is reduced to 82 lpm (22 gpm) and air consumption to 24 Nm3/h (14 scfm), increasing efficiency.

Technical Data
The document provides technical specifications for the PX400 pump, including dimensions, weight, and maximum flow rate. It emphasizes not exceeding 8.6 bar (125 psig) air supply pressure.

Specifications
The Wilden PX400 pump specifications include a height of 668 mm (26.3”), width of 478 mm (18.8”), and depth of 315 mm (12.4”). It is made of polypropylene and weighs 24 kg (52 lbs). The air inlet is 19 mm (3/4”), and both the inlet and outlet are 38 mm (1 1/2”).

Performance
The pump has a maximum flow rate of 447 lpm (118 gpm) and can handle solids up to 6.4 mm (1/4”). The displacement per stroke is 1.1 liters (0.30 gallons) at 4.8 bar (70 psig) air inlet pressure against a 2.1 bar (30 psig) head pressure. The suction lift capability is 5.5 m dry (18.2’) and 9.0 m wet (29.5’).

Efficiency Management System (EMS)
The EMS optimizes pump performance for specific applications. The pump is delivered with EMS set to setting 4 for maximum flow. The EMS curve helps determine flow and air consumption at each setting. For example, at EMS setting 4, the pump achieved a flow rate of 182 lpm (48 gpm) using 95 Nm3/h (56 scfm) of air at 4.1 bar (60 psig) air inlet pressure and 2.1 bar (30 psig) discharge pressure. By adjusting to EMS setting 3, the flow rate was reduced to 158 lpm (42 gpm) and air consumption to 74 Nm3/h (44 scfm), improving efficiency by reducing flow by 13% and air consumption by 22%.

Recommendations
Do not exceed 8.6 bar (125 psig) air supply pressure. The EMS can be adjusted for specific needs, and interpolation between setting curves is possible for intermediate EMS settings.

Suction Lift Curves
The document includes suction lift capability curves for different diaphragm materials, including TPE, traditional rubber, and PTFE diaphragms.
