PRINCIPLE OF PUMP OPERATION

This ap swing check valve pump is powered by compressed air and is a 1:1 pressure ratio design. It alternately pressurizes

the inner side of one diaphragm chamber, while simultaneously exhausting the other inner chamber. This causes the diaphragms,

which are connected by a common rod, to move endwise. Air pressure is applied over the entire surface of the diaphragm, while

liquid is discharged from the opposite side. The diaphragm operates under a balanced condition during the discharge stroke,

which allows the unit to be operated at discharge heads over 200 feet (61 meters) of water head.

Since the diaphragms are connected by a common rod, secured by plates to the center of the diaphragms, one diaphragm

performs the discharge stroke, while the other is pulled to perform the suction stroke in the opposite chamber.

For maximum diaphragm life, keep the pump as close to the liquid being pumped as possible. Positive suction head in excess

of 10 feet of liquid (3.048 meters) may require a back pressure regulating device. This will maximize diaphragm life.

Alternate pressuring and exhausting of the diaphragm chamber is performed by means of an externally mounted, pilot operated,

four-way spool type air distribution valve. When the spool shifts to one end of the valve body, inlet air pressure is applied to

one diaphragm chamber and the other diaphragm chamber exhausts. When the spool shifts to the opposite end of the valve

body, the porting of chambers is reversed. The air distribution valve spool is moved by an internal pilot valve which alternately

pressurizes one side of the air distribution valve spool, while exhausting the other side. The pilot valve is shifted at each end of

the diaphragm stroke by the diaphragm plate coming in contact with the end of the pilot valve spool. This pushes it into position

for shifting of the air distribution valve.

The chambers are manifolded together with a suction and discharge check valve for each chamber, maintaining ow in one

direction through the pump.

INSTALLATION & START-UP

Locate the pump as close to the product being pumped as possible, keeping suction line length and number of ttings to a

minimum. Do not reduce line size.

For installations of rigid piping, short exible sections of hose should be installed between pump and piping. This reduces

vibration and strain to the piping system. A pulsation dampener is recommended to further reduce pulsation in ow.

This pump was tested at the factory prior to shipment and is ready for operation. It is completely self-priming from a dry start

for suction lifts of 20 feet (6.096 meters) or less. For suction lifts exceeding 20 feet of liquid, ll the chambers with liquid prior to

priming.

AIR SUPPLY

Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet to an air supply of sufcient capacity and

pressure required for desired performance. When the air line is solid piping, use a short length of exible hose (not less than 3/4"

(19mm) in diameter) between pump and piping to eliminate strain to pipes.

AIR INLET & PRIMING

For start-up, open an air valve approximately 1/2" to 3/4" turn. After the unit primes, an air valve can be opened to increase

ow as desired. If opening the valve increases cycling rate, but does not increase ow rate, cavitation has occurred, and the

valve should be closed slightly.

For the most efcient use of compressed air and the longest diaphragm life, throttle the air inlet to the lowest cycling rate that

does not reduce ow.

A NOTE ABOUT AIR VALVE LUBRICATION

The pump’s pilot valve and main air valve assemblies are designed to operate WITHOUT lubrication. This is the

preferred mode of operation. There may be instances of personal preference, or poor quality air supplies when lubrication of

the compressed air supply is required. The pump air system will operate with properly lubricated compressed air supplies. Proper

lubrication of the compressed air supply would entail the use of an air line lubricator set to deliver one drop of 10 weight, non-

detergent oil for every 20 SCFM of air the pump consumed at its point of operation. Consult the pump’s published Performance

Curve to determine this.

It is important to remember to inspect the sleeve and spool set routinely. It should move back and forth freely. This is most

important when the air supply is lubricated. If a lubricator is used, oil accumulation will, over time, collect any debris from the

compressed air. This can prevent the pump from operating properly.

Water in the compressed air supply can create problems such as icing or freezing of the exhaust air causing the pump to

cycle erratically, or stop operating. This can be addressed by using a point of use air dryer (available from Warren Rupp) to

supplement a plant’s air drying equipment. This device will remove excess water from the compressed air supply and alleviate

the icing or freezing problem.

EXTERNALLY SERVICEABLE AIR DISTRIBUTION SYSTEM

Please refer to the exploded view drawing and parts list in the Service Manual supplied with your pump. If you need replacement

or additional copies, contact your local Distributor, or the factory Literature Department at the number shown below. To receive

the correct manual, you must specify the MODEL information found on the name plate of the pump.

MODELS WITH 1" SUCTION/DISCHARGE OR LARGER AND METAL CENTER SECTIONS

The main air valve sleeve and spool set is located in the valve body mounted on the pump with four hex head capscrews. The

valve body assembly is removed from the pump by removing these four hex head capscrews.

With the valve body assembly off the pump, access to the sleeve and spool set is made by removing four hex head capscrews

(each end) on the end caps of the valve body assembly. With the end caps removed, slide the spool back and forth in the sleeve.

The spool is closely sized to the sleeve and must move freely to allow for proper pump operation. An accumulation of oil, dirt or

other contaminants from the pump’s air supply, or from a failed diaphragm, may prevent the spool from moving freely. This can

cause the spool to stick in a position that prevents the pump from operating. If this is the case, the sleeve and spool set should

be removed from the valve body for cleaning and further inspection.

Remove the spool from the sleeve. Using an arbor press or bench vise (with an improvised mandrel), press the sleeve from

the valve body. Take care not to damage the sleeve. At this point, inspect the o-rings on the sleeve for nicks, tears or abrasions.

Damage of this sort could happen during assembly or servicing. A sheared or cut o-ring can allow the pump’s compressed air

supply to leak or bypass within the air valve assembly, causing the pump to leak compressed air from the pump air exhaust or not

cycle properly. This is most noticeable at pump dead head or high discharge pressure conditions. Replace any of these o-rings as

required or set up a routine, preventive maintenance schedule to do so on a regular basis. This practice should include cleaning

the spool and sleeve components with a safety solvent or equivalent, inspecting for signs of wear or damage, and replacing

worn components.

To re-install the sleeve and spool set, lightly lubricate the o-rings on the sleeve with an o-ring assembly lubricant or lightweight

oil (such as 10 wt. air line lubricant). Press the set into the valve body easily, without shearing the o-rings. Re-install one end cap,

gasket and bumper on the valve body. Using the arbor press or bench vise that was used in disassembly, press the sleeve back

into the valve body. You may have to clean the surfaces of the valve body where the end caps mount. Material may remain from

the old gasket. Old material not cleaned from this area may cause air leakage after reassembly. Take care that the bumper stays

in place allowing the sleeve to press in all the way. Reinstall the spool, the opposite end cap, gasket and bumper on the valve

body. After inspecting and cleaning the gasket surfaces on the valve body and intermediate, reinstall the valve body on the pump

using new gaskets. Tighten the four hex head capscrews evenly and in an alternating cross pattern.

that the bumper stays in place allowing the sleeve to press in all the way. Reinstall the spool, opposite end cap, gasket and

bumper on the valve body. After inspecting and cleaning the gasket surfaces on the valve body and intermediate, reinstall the

valve body on the pump using new gaskets. Tighten the four hex head capscrews evenly and in an alternating cross pattern.

AIR EXHAUST

If a diaphragm fails, the pumped liquid or fumes can enter the air end of the pump, and be exhausted into the atmosphere.

When pumping hazardous or toxic materials, pipe the exhaust to an appropriate area for safe disposition.

This pump can be submerged if materials of construction are compatible with the liquid. The air exhaust must be piped above

the liquid level. Piping used for the air exhaust must not be smaller than 1" (2.54 cm). Reducing the pipe size will restrict air ow

and reduce pump performance .When the product source is at a higher level than the pump (ooded suction), pipe the exhaust

higher than the product source to prevent siphoning spills.

Freezing or icing-up of the air exhaust can occur under certain temperature and humidity conditions. Use of an air dryer unit

should eliminate most icing problems.

BETWEEN USES

When used for materials that tend to settle out or transform to solid form, the pump should be completely ushed after each

use, to prevent damage. Product remaining in the pump between uses could dry out or settle out. This could cause problems

with valves and diaphragms at re-start. In freezing temperatures, the pump must be drained between uses in all cases.

FLAP VALVE SERVICING

Valve inspection requires removal of 3/8" hex nuts and elbows. When the top suction elbows are removed, the valve and

seat are connected as an assembly. When the bottom discharge elbows are removed, the valve and seat stay with the outer

chamber. Visual inspection and cleaning is possible. If parts are to be replaced, remove the self-locking nuts and all parts

are accessible.

DIAPHRAGM SERVICING

Diaphragms can be inspected or the diaphragm assembly removed without removing the suction and discharge anges.

Remove (8) nuts around the chamber ange, and the housing assembly will pull off. Flap valves can be inspected for proper

seating at this point as well as the diaphragm. Use care to keep foreign matter from behind the diaphragm. The opposite

diaphragm may be inspected by the same procedure. If either diaphragm has to be replaced, follow closely these steps:

Pull the outer diameter of one diaphragm off the (8) capscrews. NOTE: One side only! On the free diaphragm assembly, use a 3/8"

allen wrench to turn the assembly (diaphragm, plates and screw) loose from the shaft. Once the assembly has turned, it will turn out by

hand by use of the diaphragm. Now the opposite diaphragm assembly and the drive shaft will pull free from the capscrews and pump

intermediate assembly. The interior components consisting of sleeve bearings, rod seals, and pilot valve actuator bushings are

now accessible for service if required. Hold the shaft in a clamping device making sure to protect surface of shaft so as not to

scratch or mar it in any way. The diaphragm assembly will turn loose. To disassemble the components, turn a 1/4"-20 capscrew

by hand into the tapped hole in the inner plate. This keeps the plate from turning while the socket head capscrew is removed.

To do this, place assembly in a vise so the two protruding ends of screws are loose in the vise jaws (about 3/4" apart). Turn the

center screw loose from the back plate and the assembly will come apart.

REASSEMBLY

All procedures for reassembling the pump are the reverse of the previous instructions with further instructions as shown:

1. The diaphragm assemblies are to be installed with the natural bulge outward or toward the head of the center screw. Make

sure both plates are installed with outer radii against the diaphragm. After all components are in position in a vise and hand

tight, set a torque wrench for 480 inch pounds (40 ft. pounds) (54.23 Newton meters) or, 600 inch pounds (50 ft. pounds)

(67.79 Newton meters) for Santoprene, using a (3/8") allen head socket. After each diaphragm sub assembly has been

completed, thread one assembly into the shaft (held near the middle in a vise having soft jaws to protect the nish) making sure

the stainless steel washer is in place on the capscrew.

Make sure 1/4"-20 mounting screw has been removed and that the bumper (Item #19 on drawing) is in place in the shaft.

Install this sub assembly into the pump and secure by placing the outer chamber housing and capscrews on the end

with the diaphragm. This will hold the assembly in place while the opposite side is installed. Make sure the last diaphragm

assembly is torqued to 30 ft. lbs. (40.67 Newton meters) before placing the outer diaphragm over the capscrews. If the holes

in the diaphragm ange do not line up with the holes in the chamber ange, turn the diaphragm assembly in the direction of

tightening to align the holes so that the capscrews can be inserted. This nal torquing of the last diaphragm assembly will lock

the two diaphragm assemblies together. Place remaining outer chamber on the open end and tighten down the securing nuts

x75mfvmdl2sm-rev0411 Page 8

gradually and evenly on both sides.

Caution should be used while reassembling Flap valves. The valves are designed for some preload over the retainer hinge pad.

This is done to insure proper face contact with the seat. After all parts are in place, tighten the lock nuts down on the assembly

to the point where visual inspection shows that seat and valve face mate without gap. This is important for dry prime. However,

after priming action has started, valves will function due to differential pressure without concern or trouble.

PILOT VALVE

The pilot valve assembly is accessed by removing the main air distribution valve body from the pump and lifting the pilot valve

body out of the intermediate housing.

Most problems with the pilot valve can be corrected by replacing the o-rings. Always grease the spool prior to inserting it

into the sleeve. If the sleeve is removed from the body, reinsertion must be at the chamfered side. Grease the o-rings to slide

the sleeve into the valve body. Securely insert the retaining ring around the sleeve. When reinserting the pilot valve, push both

plungers (located inside the intermediate bracket) out of the path of the pilot valve spool ends to avoid damage.

PILOT VALVE ACTUATOR

Bushings for the pilot valve actuators are threaded into the intermediate bracket from the outside. The plunger may be removed for

inspection or replacement. First remove the air distribution valve body and the pilot valve body from the pump. The plungers can be located

by looking into the intermediate. It may be necessary to use a ne piece of wire to pull them out. The bushing can be turned out through the

inner chamber by removing the outer chamber assembly. Replace the bushings if pins have bent.
