CAUTIONS—READ FIRST!

CAUTION: Do not apply compressed air to the

exhaust port — pump will not function.

CAUTION: Do not over-lubricate air supply —

excess lubrication will reduce pump performance. Pump is pre-lubed.

TEMPERATURE LIMITS:

Neoprene –17.7°C to 93.3°C 0°F to 200°F Buna-N –12.2°C to 82.2°C 10°F to 180°F Nordel Viton® –40°C to 176.7°C –40°F to 350°F Saniﬂ ex™ –28.9°C to 104.4°C –20°F to 220°F Polytetraﬂ uoroethylene (PTFE)

4.4°C to 104.4°C 40°F to 220°F Polyurethane –12.2°C to 65.6°C 10°F to 150°F Tetra - F l ex™ PTFE w/ N e oprene Backed

4.4°C to 107.2°C 40°F to 225°F Tetra - F l ex™ PTFE w/ N ordel® Backed

-10°C to 137°C 14°F to 280°F

NOTE: Not all materials are available for all models. Refer to Section 2 for material options for your pump.

CAUTION: When choosing pump materials, be

sure to check the temperature limits for all wetted components. Example: Viton® has a maximum limit of 176.7°C (350°F) but polypropylene has a maximum limit of only 79°C (175°F).

CAUTION: Maximum temperature limits are

based upon mechanical stress only. Certain chemicals will signiﬁ cantly reduce maximum safe operating temperatures. Consult Chemical Resistance Guide (E4) for chemical compatibility and temperature limits.

WARNING : Prevention of static sparking — If

static sparking occurs, ﬁ re or explosion could result. Pump, valves, and containers must be grounded to a proper grounding point when handling ﬂ ammable ﬂ uids and whenever discharge of static electricity is a hazard.

CAUTION: Do not exceed 8.6 bar (125 psig) air

supply pressure.

CAUTION: The process ﬂ uid and cleaning ﬂ uids

must be chemically compatible with all wetted pump components. Consult Chemical Resistance Guide (E4).

–51.1°C to 137.8°C –60°F to 280°F

CAUTION: Do not exceed 82°C (180°F) air inlet

temperature for Pro-Flo V™ models.

CAUTION: Pumps should be thoroughly ﬂ ushed

before installing into process lines. FDA and USDA approved pumps should be cleaned and/ or sanitized before being used.

CAUTION: Always wear safety glasses when

operating pump. 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 ﬂ uid to ﬂ ow into a suitable container.

CAUTION: Blow out air line for 10 to 20 seconds

before attaching to pump to make sure all pipeline debris is clear. Use an in-line air ﬁ lter. A 5µ (micron) air ﬁ lter is recommended.

NOTE: When installing Teﬂ on® diaphragms, it is

important to tighten outer pistons simultaneously (t urning in opposite dir ections) to e nsure tight ﬁ t. (See torque speciﬁ cations in Section 7.)

NOTE: Cast Iron Teﬂ on®-ﬁ tted pumps come

standard from the factory with expanded Teﬂ on gaskets installed in the diaphragm bead of the liquid chamber. Teﬂ on® gaskets cannot be reused. Consult PS-TG for installation instructions during reassembly.

NOTE: Before starting disassembly, mark a line

fro m each liquid cha mber t o its c orrespo ndin g air chamber. This line will assist in proper alignment during reassembly.

CAUTION: Pro-Flo® pumps cannot be used in

submersible applications. Pro-Flo V™ is available in both submersible and non-submersible options. Do not use non-submersible Pro-Flo V™ models in submersible applications. Turbo-Flo® pumps can also be used in submersible applications.

CAUTION: Tighten all hardware prior to installation.

Section 3 How It Works—Pump & Air

Section 3

HOW IT WORKS—PUMP

The Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show ﬂ ow pattern through the pump upon its initial stroke. It is assumed the pump has no ﬂ uid in it prior to its initial stroke.

FIGURE 1 The air valve dir ects pre ssurized air to the back side of diaphragm A. 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 ﬂ uid into the inlet manifold forcing the inlet valve ball off its seat. Liquid is free to move past the inlet valve ball and ﬁ ll the liquid chamber (see shaded area).

FIGURE 2 When the pressurized diaphragm, diaphr agm A, re ache s the limit of i ts dis charge 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 ﬂ uid to ﬂ 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 ﬂ uid into the inlet manifold of the pump. The inlet valve ball is f or ce d of f its s ea t a llowi ng the ﬂ uid being pumped to ﬁ 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 exhaust stroke. As the pump reaches its original starting point, each diaphragm has gone through one exhaust 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 V moving parts : the air valve spool and the pilot spool. The hear t of the system is the 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 air valve spool directs pressurized air to one air chamber while exhausting the other. The air causes the main shaf t/diaphragm assembly to shift to one side — discharging liquid on that side and pulling liquid in on the other side. 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.

Displacement per stroke was calculated at

4.8 bar (70 psig) air inlet pressure against a 2 bar (30 psig) head pressure.

Example: To pump 265 lpm (70 gpm) against a discharge pressure head of 2.8 bar (40 psig) requires 4.1 bar (60 psig) and 83 Nm3/h (49 scfm) air consumption.

Caution: Do not exceed 8.6 bar (125 psig) air supply pressure.

PERFORMANCE

Flow rates indicated on chart were determined by pumping water with a vertically mounted, side ported ball check conﬁ guration. When alternate check valve options are used, multiply ﬂ ow rate by appropriate factor. Mushroom check valve = 93%, ﬂ ap check valve = 143%. For optimum life and performance, pumps should be speciﬁ ed so that daily operation parameters will fall in the center of the pump performance curve.

SUGGESTED INSTALLATION

Wilden pumps are designed to meet the performance requirements of even the most demanding pumping applications. They have been designed and manufactured to the highest standards and are available in a variety of liquid path materials to meet your chemical resistance needs. Refer to the performance section of this manual for an in-depth analysis of the performance characteristics of your pump. Wilden offers the widest variety of elastomer options in the industry to satisfy temperature, chemical compatibility, abrasion resistance and ﬂ ex concerns.

The suction pipe size should be equivalent or larger than the diameter of the suction inlet on your Wilden pump. The suction hose must be non-collapsible, reinforced type as these pumps are capable of pulling a high vacuum. Discharge piping should also be equivalent or larger than the diameter of the pump discharge to minimize friction losses. It is critical that all ﬁ ttings and connections are airtight or a reduction or loss of pump suction capability will result.

INSTALLATION: Months of careful planning, study, and selection efforts can result in unsatisfactory pump performance if installation details are left to chance.

Premature failure and long term dissatisfaction can be avoided if reasonable care is exercised throughout the installation process.

LOCATION: Noise, safety, and other logistical factors usually dictate where equipment will be situated on the production ﬂ oor. Multiple installations with conﬂ icting requirements can result in congestion of utility areas, leaving few choices for additional pumps.

Within the framework of these and other existing conditions, every pump should be located in such a way that six key factors are balanced against each other to maximum advantage.

ACCESS: First of all, the location should be accessible. If it’s easy to reach the pump, maintenance personnel will have an easier time carrying out routine inspections and adjustments. Should major repairs become necessary, ease of access can play a key role in speeding the repair process and reducing total downtime.

AIR SUPPLY: Every pump location should have an air line large enough to supply the volume of air necessary to achieve the desired pumping rate. Do not exceed the maximum rated air pressure.

For best results, the pumps should use a 5µ (micron) air ﬁ lter, needle valve and regulator. The use of an air ﬁ lter before the pump will ensure that the majority of any pipeline contaminants will be eliminated.

SOLENOID OPERATION: When operation is controlled by a solenoid valve in the air line, three-way valves should be used. This valve allows trapped air between the valve and the pump to bleed off which improves pump performance.

MUFFLER: Sound levels are reduced below OSHA speciﬁ cations using the standard Wilden mufﬂ er. Other mufﬂ ers can be used to further reduce sound levels, but they usually reduce pump performance.

ELEVATION: Selecting a site that is well within the pump’s dynamic lift capability will assure that loss-of-prime issues will be eliminated. In addition, pump efﬁ ciency can be adversely affected if proper attention is not given to site location.

PIPING: Final determination of the pump site should not be made until the piping challenges of each possible location have been evaluated. The impact of current and future installations should be considered ahead of time to make sure that inadvertent restrictions are not created for any remaining sites.

The best choice possible will be a site involving the shortest and straightest hook-up of suction and discharge piping. Unnecessary elbows, bends, and ﬁ ttings should be avoided. Pipe sizes should be selected to keep friction losses within practical limits. All piping should be supported independently of the pump. In addition, the piping should be aligned to avoid placing stress on the pump ﬁ ttings.

Flexible hose can be installed to aid in absorbing the forces created by the natural reciprocating action of the pump. If the pump is to be bolted down to a solid location, a mounting pad placed between the pump and the foundation will assist in minimizing pump vibration. Flexible connections between the pump and rigid piping will also assist in minimizing pump vibration. If quick-closing valves are installed at any point in the discharge system, or if pulsation within a system becomes a problem, a surge suppressor (SD Equalizer should be installed to protect the pump, piping and gauges from surges and water hammer.

If the pump is to be used in a self-priming application, make sure that all connections are airtight and that the suction lift is within the model’s ability. Note: Materials of construction and elastomer material have an effect on suction lift parameters. Please refer to the performance section for speciﬁ cs.

When pumps are installed in applications involving ﬂ ooded suction or suction head pressures, a gate valve should be installed in the suction line to permit closing of the line for pump service.

Pumps in service with a positive suction head are most efﬁ cient when inlet pressure is limited to 0.5–0.7 bar (7–10 psig). Premature diaphragm failure may occur if positive suction is 0.7 bar (10 psig) and higher.

SUBMERSIBLE APPLICATIONS: Pro-Flo V™ pumps can be used for submersible applications, when using the Pro-Flo V™ submersible option. Turbo-Flo™ pumps can also be used for submersible applications. Pro-Flo pumps are not submersible.

ALL WILDEN PUMPS ARE CAPABLE OF PASSING SOLIDS. A STRAINER SHOULD BE USED ON THE PUMP INTAKE TO ENSURE THAT THE PUMP´S RATED SOLIDS CAPACITY IS NOT EXCEEDED.

NOTE: In the event of a power failure, the shut off valve should be closed, if restarting of the pump is not desirable once power is regained.

AIR OPERATED PUMPS: To stop the pump from operating in an emergency situation, simply close the shut off valve (user supplied) installed in the air supply line. A properly functioning valve will stop the air supply to the pump, therefore stopping output. This shut off valve should be located far enough away from the pumping equipment such that it can be reached safely in an emergency situation.

SUGGESTED OPERATION & MAINTENANCE

OPERATION: The Pro-Flo® and Pro-Flo V™ pumps are pre-lubricated, and do not require in-line lubrication. Additional lubrication will not damage the pump, however if the pump is heavily lubricated by an external source, the pump’s internal lubrication may be washed away. If the pump is then moved to a nonlubricated location, it may need to be disassembled and re-lubricated as described in the ASSEMBLY/ DISASSEMBLY INSTRUCTIONS.

Pump discharge rate can be controlled by limiting the volume and/or pressure of the air supply to the pump. An air regulator is used to regulate air pressure. A needle valve is used to regulate volume. Pump discharge rate can also be controlled by throttling the pump discharge by partially closing a valve in the discharge line of the pump. This action increases friction loss which reduces ﬂ ow rate. (See Section 5.) This is useful when the need exists to control the pump from a remote location. When the pump discharge pressure equals or exceeds the air supply pressure, the pump will stop; no bypass or pressure relief valve is needed, and pump damage will not occur. The pump has reached a “deadhead”

situation and can be restarted by reducing the ﬂ uid discharge pressure or increasing the air inlet pressure. The Wilden Pro-Flo on compressed air and do not generate heat, therefore your process ﬂ uid temperature will not be affected.

MAINTENANCE AND INSPECTIONS: Since each application is unique, maintenance schedules may be different for every pump. Frequency of use, line pressure, viscosity and abrasiveness of process ﬂ uid all affect the parts life of a Wilden pump. Periodic inspections have been found to offer the best means for preventing unscheduled pump downtime. Personnel familiar with the pump’s construction and service should be informed of any abnormalities that are detected during operation.

RECORDS: When service is required, a record should be made of all necessary repairs and replacements. Over a period of time, such records can become a valuable tool for predicting and preventing future maintenance problems and unscheduled downtime. In addition, accurate records make it possible to identify pumps that are poorly suited to their applications.

and Pro-Flo V™ pumps run solely

Pump will not run or runs slowly.

1. Ensure that the air inlet pressure is at least 0.4 bar (5 psig) above startup pressure and that the differential pressure (the difference between air inlet and liquid discharge pressures) is not less than 0.7 bar (10 psig).

2. Check air inlet ﬁ lter for debris (see recommended installation).

3. Check for extreme air leakage (blow by) which would indicate worn seals/bores in the air valve, pilot spool, main shaft.

4. Disassemble pump and check for obstructions in the air passageways or objects which would obstruct the movement of internal parts.

5. Check mating surfaces of ﬂ ap valve assembly.

6. Check for sticking ball check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace ball check valves and seats with proper elastomers. Also, as the check valve balls wear out, they become smaller and can become stuck in the seats. In this case, replace balls and seats.

7. Check for broken inner piston which will cause the air valve spool to be unable to shif t.

8. Remove plug from pilot spool exhaust.

2. Verify that vacuum required to lift liquid is not greater than the vapor pressure of the material being pumped (cavitation).

3. Check for sticking ball check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace ball check valves and seats with proper elastomers. Also, as the check valve balls wear out, they become smaller and can become stuck in the seats. In this case, replace balls and seats.

Remove the air valve spool from the air valve body by threading one air valve bolt into the end of the air valve spool and gently sliding the spool out of the air valve body. Inspect seals for signs of wear and replace entire assembly if necessary. Use caution when handling air valve spool to prevent damaging seals. Note: seals should not be removed from assembly. Seals are not sold separately.

Notched End

Step 10

Using an o-ring pick, gently remove the o-ring from the opposite side of the “notched end” on one side of the pilot spool. Gently remove the pilot spool from pilot spool sleeve and inspect for nicks, gouges and wear. Replace pilot sleeve or outer sleeve o-rings if necessary. During re-assembly, never insert the pilot spool into the sleeve with the “notched end” ﬁ rst, this end incorporates the urethane o-ring and will be damaged as it slides over the ports cut in the sleeve. Note: seals should not be removed from pilot spool. Seals are not sold separately.

REASSEMBLY HINTS & TIPS

ASSEMBLY:

Upon performing applicable maintenance to the air distrib ution system, th e pump can now be reas sembled. Please refer to the disassembly instructions for photos and parts placement. To reassemble the pump, follow the disassembly instructions in reverse order. The air distribution system needs to be assembled ﬁ rst, then the diaphragms and ﬁ nally the wetted path. The following tips will assist in the assembly process.

• Lubricate air valve bore, center section shaft and pilot spool bore with NLGI grade 2 white EP bearing grease or equivalent.

• Clean the inside of the center section shaft bore to ensure no damage is done to new shaft seals.

• A small amoun t NLGI grade 2 white EP bearing grease can be applied to the mufﬂ er and air valve gaskets to locate gaskets during assembly.

• Make sure that the exhaust port on the mufﬂ er plate is centered between the two exhaust ports on the center section.

• Stainless bolts should be lubed to reduce the possibility of seizing during tightening.

• Use a mallet to tamp lightly on the large clamp bands to seat the diaphragm before tightening.

SHAFT SEAL INSTALLATION:

PRE-INSTALLATION

• Once all of the old seals have been removed, the inside of the bushing should be cleaned to ensure no debris is left that may cause premature damage to the new seals.

INSTALLATION

The following tools can be used to aid in the installation of the new seals:

Needle Nose Pliers Phillips Screwdriver Electrical Tape

• Wrap electrical tape around each leg of the needle nose pliers (heat shrink tubing may also be used). This is done to prevent damaging the inside surface of the new seal.

• With a new seal in hand, place the two legs of the needle nose pliers inside the seal ring. (See Figure A.)

• Open the pliers as wide as the seal diameter will allow, then with two ﬁ ngers pull down on the top portion of the seal to form kidney bean shape. (See Figure B.)

• Lightly clamp the pliers together to hold the seal into the kidney shape. Be sure to pull the seal into as tight of a kidney shape as possible, this will allow the seal to travel down the bushing bore easier.

• With the seal clamped in the pliers, insert the seal into the bushing bore and position the bottom of the seal into the correct groove. Once the bottom of the seal is seated in the groove, release the clamp pressure on the pliers. This will allow the seal to partially snap back to its original shape.

• After the pliers are removed, you will notice a slight bump in the seal shape. Before the seal can be properly resized, the bump in the seal should be removed as much as possible. This can be done with either the Phillips screwdriver or your ﬁ nger. With either the side of the screwdriver or your ﬁ nger, apply light pressure to the peak of the bump. This pressure will cause the bump to be almost completely eliminated.

• Lubricate the edge of the shaft with white EP bearing grease.

• Slowly insert the center shaf t with a rotating motion. This will complete the resizing of the seal.

• Perform these steps for the remaining seals.
