NOTE: Not all materials are available for all

models. Refer to Section 2 for the material

options available 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 177°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 signiﬁcantly reduce maximum

safe operating temperatures. Consult Chemical

Resistance Guide for chemical compatibility and

temperature limits.

WARNING : Prevent static sparking — If static

sparking occurs, ﬁre or explosion could result.

Pump, valves and containers must be grounded

to a proper grounding point when handling

ﬂammable ﬂuids and whenever discharge of

static electricity is a hazard.

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

supply pressure.

CAUTION: The process ﬂuid and cleaning ﬂuids

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

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

temperature for Pro-Flo® SHIFT models.

CAUTION: Pumps should be thoroughly ﬂushed

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 allowing any ﬂuid to ﬂow 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 ﬁlter. A 5μ (micron) air ﬁlter is recommended.

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.

CAUTION: Pro-Flo® SHIFT is available in

both single-point exhaust (submersible) and standard (non-submersible) options. Do not use

standard Pro-Flo

SHIFT models in submersible

applications.

HOW IT WORKS—PUMP

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

FIGUR E 1 The air valve dire cts 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 ac ts as a separation membrane bet ween the compressed air and liquid; a balanced load removes 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. A tmosphe ric pressure forces ﬂuid into the inlet manifold forcing the inlet check valve off its seat. Liquid is free to move past the inlet check valve and ﬁll the liquid chamber (see shaded area).

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 check valve 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 check valve of f its seat, while the opposite discharge check valve is forced onto its seat, forcing ﬂuid to ﬂow 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 ﬂuid into the inlet manifold of the pump. The inlet check valve is forced off its seat allowing the ﬂuid being pumped to ﬁll 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 star ting 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.

NOTE: Unlike other Wilden pumps, the ﬂuid inlet of the Brahma Advanced™ pump is located at the top and the ﬂuid discharge is located at the bottom of the pump.

HOW IT WORKS—AIR DISTRIBUTION SYSTEM

The heart of the patented Pro-Flo® SHIFT Air Distribution System (ADS) is the air valve assembly. The air valve design incorporates an unbalanced spool with the small end of the spool being pressurized continuously while the large end of the spool is alternately pressurized, then exhausted to move the spool. The air valve spool directs pressurized air to one chamber while exhausting the other. The air forces the main shaft/diaphragm assembly to move to one side – discharging liquid on that side and pulling liquid in on the other side. When the shaft reaches the end of the stroke, the inner piston actuates the pilot spool, which controls the air to the large end of the air valve spool. The repositioning of the air valve spool routes the air to the other air chamber. The air control spool allows air to ﬂow freely into the air chamber for the majority of each pump stroke, but it signiﬁcantly restricts the ﬂow of air into the air chamber when activated by the inner piston near the end of the each stroke.

PS1510 METAL SUCTION-LIFT CAPABILITY

Suction-lift curves are calibrated for pumps operating at 305 m (1,000') above sea level. This chart is meant to be a guide only. There are many variables that can affect your pump’s operating characteristics. The

number of intake and discharge elbows, viscosity of pumping ﬂuid, elevation (atmospheric pressure) and pipe friction loss all affect the amount of suction lift your pump will attain.

Section 6

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 wetted-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 ﬂex concerns.

The suction pipe size should be at least the equivalent or larger than the diameter size 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 the equivalent or larger than the diameter of the pump discharge which will help reduce friction losses. It is critical that all ﬁttings 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 ﬂoor. Multiple installations with conﬂicting 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 is 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. Use air pressure up to a maximum of

8.6 bar (125 psig) depending on pumping requirements.

For best results, the pumps should use a 5µ (micron) air ﬁlter, needle valve and regulator. The use of an air ﬁlter 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. Pumping volume can be estimated by counting the number of strokes per minute and then multiplying the ﬁgure by the displacement per stroke.

MUFFLER: Sound levels are reduced below OSHA speciﬁcations using the standard Wilden mufﬂer. Other mufﬂers 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 ensure that loss-of-prime issues will be eliminated. In addition, pump efﬁciency 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 hookup of suction and discharge piping. Unnecessary elbows, bends, and ﬁttings 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 ﬁttings.

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 options have an effect on suction lift parameters. Please refer to the performance section for speciﬁcs.

When pumps are installed in applications involving ﬂooded 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 efﬁcient 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: be used for submersible applications when using the Pro-Flo® SHIFT's single-point exhaust option

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.

CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG) AIR SUPPLY PRESSURE [3.4 BAR (50 PSIG) FOR UL-LISTED MODELS.

SUGGESTED INSTALLATION SUGGESTED OPERATION & MAINTENANCE

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.

NOTE: The ﬂuid inlet to the PS Brahma pump is located at the top and the ﬂuid discharge is located at the bottom of the pump.

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-of f valve should be located far enough away from the pumping equipment such that it can be reached safely in an emergency situation.

WILDEN PUMP & ENGINEERING, LLC 8 WIL-11320-E-01

Page 11

SUGGESTED OPERATION & MAINTENANCE

OPERATION : The PS Brahma is pre-lubricated, and does 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 non-lubricated location, it may need to be disassembled and re-lubricated as described in the DISASSEMBLY/REASSEMBLY 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. Pumpdischarge 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 ﬂow 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

TROUBLESHOOTING

be restarted by reducing the ﬂuid discharge pressure or increasing the air inlet pressure. The Wilden Pro-Flo® SHIFT pumps run solely on compressed air and do not generate heat, therefore your process ﬂuid 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 ﬂuid 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.

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 ﬁlter for debris (see SUGGESTED INSTALLATION).

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

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

5. Check mating surfaces of ﬂap valve assembly.

6. Check for sticking check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace check valves with proper elastomers.

7. Check for broken inner piston that would cause the air valve spool to be unable to shift.

8. Remove plug from pilot spool exhaust.

Pump runs, but little or no product ﬂows.

1. Check for pump cavitation; decrease pump speed to allow thick material to ﬂow into liquid chambers.

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 check valves. If material being pumped is not compatible with pump elastomers, swelling may occur. Replace check valves with proper elastomers.

Pump air valve freezes.

1. Check for excessive moisture in compressed air. Either install a dryer or hot-air generator for compressed air. Alternatively, a coalescing ﬁlter may be used to remove the water from the compressed air in some applications.

Air bubbles in pump discharge.

1. Check for ruptured diaphragm.

2. Check tightness of outer pistons (refer to Section 7).

3. Check tightness of fasteners and integrity of O-rings and seals, especially at intake manifold.

4. Ensure pipe connections are airtight.

Product comes out air exhaust.

1. Check for diaphragm rupture.

2. Check tightness of outer pistons to shaft.

REASSEMBLY HINTS & TIPS

ASS EM B LY:

Upon performing applicable maintenance to the air distrib ution system, t he pump can now be re assembled . 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 ﬁrst, then the diaphragms and ﬁnally 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 amount of NLGI grade 2 white EP bearing grease can be applied to the mufﬂer and air valve gaskets to lubricate gaskets during assembly.

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

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

• Use a mallet to tap 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.

INSTALLATI O N

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 ﬁngers pull down on the top portion of the seal to form a kidney shape. (See Figure B.)

• Lightly clamp the pliers together to hold the seal in 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 ﬁnger. With either the side of the screwdriver or your ﬁnger, 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

NLGI grade 2

white EP bearing grease.

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

• Perform these steps for the remaining seals.
