PWM , Chester Music The inspiration for the Dance Preludes came from Tadeusz Ochlewski, the director of PWM Edition in Cracow, who wished to commission a cycle of easy pieces based on folk melodies for violin and piano to be used in secondary schools.

PX Performance Operating Principal. If the set screw is loose when the pump is pressurized, it could eject and cause injury to anyone in the area.

Pump is pre-lubed. Consult Chemical Resistance Guide E4. If diaphragm rupture occurs, material being pumped may be forced out air exhaust. CAUTION: Before any maintenance or repair is attempted, the compressed air line to the pump should be disconnected and all air pressure allowed to bleed from pump. Disconnect all intake, discharge and air lines. Drain the pump by turning it upside down and allowing any uid to ow into a suitable container.

Use an in-line air lter. A 5 micron air lter is recommended. See torque specications in Section 7. Teon gaskets cannot be re-used. Consult PS-TG for installation instructions during reassembly. This excludes Pro-Flo P Advanced metal pumps. NOTE: Before starting disassembly, mark a line from each liquid chamber to its corresponding air chamber.

This line will assist in proper alignment during reassembly. Turbo-Flo pumps can also be used for submersible applications when using the Turbo-Flo submersible option. CAUTION: The gas outlet of CSA configured pumps must be vented to a safe location in accordance with local codes or, in the absence of local codes, an industry or nationally recognized code having jurisdiction over the specified installation. The ground connection is marked with a tag having the grounding symbol.

NOTE: Not all materials are available for all models. Refer to Section 2 for material options for your pump. Example: Viton has a maximum limit of C F but polypropylene has a maximum limit of only 79C F. Certain chemicals will signicantly reduce maximum safe operating temperatures. Consult Chemical Resistance Guide E4 for chemical compatibility and temperature limits. Pump, valves, and containers must be grounded to a proper grounding point when handling ammable uids and whenever discharge of static electricity is a hazard.

Improper grounding can cause improper and dangerous operation. Approved, Side-ported 1 inlet and discharge manifolds U. Wilden UL Listed pumps have been evaluated for use at a 25 C 77F ambient temperature with a maximum inlet pressure of 3. These drawings show ow pattern through the pump upon its initial stroke. It is assumed the pump has no uid in it prior to its initial stroke.

The compressed air is applied directly to the liquid column separated by elastomeric diaphragms. The diaphragm acts as a separation membrane between the compressed air and liquid, balancing the load and removing mechanical stress from the diaphragm. The compressed air moves the diaphragm away from the center of the pump.

The opposite diaphragm is pulled in by the shaft connected to the pressurized diaphragm. Diaphragm B is on its suction stroke; air behind the diaphragm has been forced out to atmosphere through the exhaust port of the pump. The movement of diaphragm B toward the center of the pump creates a vacuum within chamber B. Atmospheric pressure forces uid into the inlet manifold forcing the inlet valve ball off its seat.

Liquid is free to move past the inlet valve ball and ll the liquid chamber see shaded area. FIGURE 2 When the pressurized diaphragm, diaphragm A, reaches the limit of its discharge stroke, the air valve redirects pressurized air to the back side of diaphragm B.

The pressurized air forces diaphragm B away from the center while pulling diaphragm A to the center.

Diaphragm B is now on its discharge stroke. Diaphragm B forces the inlet valve ball onto its seat due to the hydraulic forces developed in the liquid chamber and manifold of the pump. These same hydraulic forces lift the discharge valve ball off its seat, while the opposite discharge valve ball is forced onto its seat, forcing uid to ow through the pump discharge. The movement of diaphragm A toward the center of the pump creates a vacuum within liquid chamber A.

Atmospheric pressure forces uid into the inlet manifold of the pump. The inlet valve ball is forced off its seat allowing the uid being pumped to ll the liquid chamber. FIGURE 3 At completion of the stroke, the air valve again redirects air to the back side of diaphragm A, which starts diaphragm B on its suction stroke.

As the pump reaches its original starting point, each diaphragm has gone through one suction and one discharge stroke. This constitutes one complete pumping cycle. The pump may take several cycles to completely prime depending on the conditions of the application. The Pro-Flo patented air distribution system incorporates two moving parts: the air valve spool and the pilot spool.

The heart of the system is the air valve spool and air valve. This valve design incorporates an unbalanced spool. The smaller end of the spool is pressurized continuously, while the large end is alternately pressurized then exhausted to move the spool. The spool directs pressurized air to one air chamber while exhausting the other. When the shaft reaches the end of its stroke, the inner piston actuates the pilot spool, which pressurizes and exhausts the large end of the air valve spool.

The repositioning of the air valve spool routes the air to the other air chamber. Aluminum 11 kg 24 lbs. Ductile Iron 21 kg 47 lbs. Air Inlet Flow Rate Size Solids Displacement per stroke was calculated at 4. Example: To pump See dot on chart. Flow rates indicated on chart were determined by pumping water. For optimum life and performance, pumps should be specied so that daily operation -parameters will fall in the center of the pump performance curve. Caution: Do not exceed 8. Please read all cautions and suggested installation sections before operating any Wilden product.

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 ow and efciency that best meets the application needs. Pro-Flo X provides higher performance, lower operational exceeds costs and exibility that previous industry standards. Each dial setting represents an entirely different ow curve Pro-Flo X pumps are shipped from the factory on setting 4, which is the highest ow rate setting possible Moving the dial from setting 4 causes a decrease in ow and an even greater decrease in air consumption.

When the air consumption decreases more than the ow rate, efciency is improved and operating costs are reduced. This is an example showing how to determine ow rate and air consumption for your Pro-Flo X pump using the Efciency Management System EMS curve and the performance curve. For this example we will be using 4. This identies the ow X Factor in this case, 0. Step 3: Calculating performance for specific EMS setting.

Multiply the ow rate 8. Multiply the air consumption 9. Step 1: Identifying performance at setting 4. Locate the curve that represents the ow rate of the pump with 4. Mark the point where this curve crosses the horizontal line representing 2. Figure 1. After locating your performance point on the ow curve, draw a vertical line downward until reaching the bottom scale on the chart. Identify the ow rate in this case, 8. Observe location of performance point relative to air consumption curves and approximate air consumption value in this case, 9.

Step 2: Determining flow and air X Factors. Locate your discharge pressure 40 psig on the vertical axis of the EMS curve Figure 2.

Follow along the 2. Mark the points where the EMS curves intersect the horizontal discharge pressure line. The ow rate and air consumption at Setting 2 are found to be 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 specic application.

For this example we will be using an application requirement of This example will illustrate how to calculate the air consumption that could be expected at this operational point. Higher air pressures will typically allow the pump to run more efciently, however, available plant air pressure can vary greatly.
