SERVICE AND OPERATING MANUAL

CONTAINMENT DUTY Type 1

PRINCIPLE OF OPERATION

This ball 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.

This SandPIPER pump differs from others in that it utilizes four diaphragms instead of two. The two rod-connected diaphragms are the driver diaphragms,

and the other two (outermost) diaphragms are the actual pumping diaphragms. Each driver diaphragm (of Neoprene or other elastomer), and the pumping diaphragm (of TFE), are separated by a chamber lled with liquid which transmits the

reciprocating motion of the driver diaphragm to the pumping diaphragm. The pumping diaphragms, create the alternating suction and discharge action to each outer diaphragm chamber. The pumping diaphragms are the only ones in contact with the liquid being pumped.

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 Warren Rupp Tranquilizer

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 10-15 feet

(9-14 meters) or less. For suction lifts exceeding 15 feet of liquid, ll the chambers

with liquid prior to priming.

surge suppressor is recommended to further reduce

et2dl2sm-0614 Model ET2-M Type 1 Page 3

AIR SUPPLY

Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet (see Fig. 1) 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 ¾" [19mm] in diameter) between pump and piping to eliminate strain to

pipes.

AIR INLET & PRIMING

For start-up, open an air valve approximately ½ to ¾ 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 SandPIPER 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 sup-

ply would entail the use of an air line lubricator (available from Warren Rupp) set to deliver one drop of 10 wt., 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.

ESADS: 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 Warren Rupp Distributor, or the Warren Rupp factory Literature Department at the number shown below. To receive the correct manual, you must specify the MODEL and

TYPE information found on the name plate of the pump.

MODELS WITH 1" SUCTION/DISCHARGE OR LARGER, AND NON-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 a retaining ring (each end) securing the end cap on 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

Model ET2-M Type 1 Page 4 et2dl2sm-0614

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, and retaining ring on the valve body. Using the arbor press or bench vise that was used in disassembly, press the sleeve back into the valve body. Re-install the spool, keeping the counter-bored end toward you, and install the spring, opposite end cap and retaining ring on the valve body. After inspecting and cleaning the gasket surfaces on the valve body and intermediate, re-install the valve body on the pump using new gaskets. Tighten the four hex head capscrews evenly and in an alternating cross pattern, at 150 in./lbs.

(16.94 Newton meters).

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 of the air exhaust can occur under certain temperature and humidity conditions. Use of a Warren Rupp Extractor/Dryer unit should eliminate most

icing problems. Check the exhaust periodically for build-up of ice or contaminants (see Fig. 2).

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.

FILLING OF DRIVER CHAMBER WITH LIQUID

The driver chambers are lled at the factory with water.

If you need to substitute another liquid to prevent system contamination, rst con-

sult the factory for chemical compatibility with pump construction.

Follow the steps listed below to replace the liquid in the pump after disassembly or

liquid loss:

1. Filling is accomplished through the pipe plugs at the top of the liquid driver

chamber (see Fig. 3).

2. After the driver uid has been emptied from the pump, the driver diaphragms will

naturally come to center.

3. Remove the entire discharge manifold assembly exposing the ports in the outer

diaphragm chambers.

4. Fill either side with 2640 ml. (89.3 . oz.) by volume with the driver liquid. It is

imperative that the driver liquid chambers be lled with the correct amount of driver

liquid as too little or too much will cause premature diaphragm failure and erratic pumping.

5. After lling with the proper amount of liquid, if the liquid does not come to the top of the ll hole, pressure should be applied to the Virgin PTFE diaphragm with a blunt tool through the discharge material ow port in the outer chamber until it does come to the top (see Fig. 4). To facilitate this lling, a taper punch can be used in the hole of

the rod to manually shift the pump.

6. When the driver uid rises to the top of the ll plug hole, screw the boss plug, with o-ring installed, into the chamber (see Fig. 5). (Do not overtighten.) Remember to keep pressure on the Virgin PTFE diaphragm until the boss plug is tight to prevent air

from drawing back into the chamber.

7. Filling the opposite side is accomplished in the same manner as described in 5 and 6. The correct amount of uid will come to the top of the ll hole. Screw in the

boss plug.

et2dl2sm-0614 Model ET2-M Type 1 Page 5

CHECK VALVE SERVICING

Need for inspection or service is usually indicated by poor priming, unstable cy-

cling, reduced performance or the pump’s cycling but not pumping.

Remove the six ange bolts securing the inlet and outlet anges to the manifold.

Inspect the surfaces of both check valve and seat for wear or damage that could

prevent proper sealing. If pump is to prime properly, valves must seat air tight (see Fig. 6).

DIAPHRAGM SERVICING

Driver Diaphragms:

Drain the driver diaphragm chamber by removing the boss plug on the underside

of the driver chamber. NOTE: This is also the part used for leak detector probes. Remove twelve bolts securing the two manifolds to the chambers. Remove eight bolts

securing the diaphragm chamber. This permits inspection of the TFE diaphragm and

the driver diaphragm. Loosen the plate which secures the diaphragm and plate to the rod by keeping the diaphragm engaged with the inner diaphragm chamber. Insert two or three capscrews through the bolt holes so the diaphragm cannot rotate when loosening. The diaphragm plates, diaphragm and bumper will now come off the assembly. Repeat all actions if the other diaphragm needs to be inspected or replaced.

NOTE: See “Filling of Driver Chamber with Liquid” for the correct procedure to

recharge the pump for operation.

Reassembly is the reverse of the tear down. During reassembly, be sure the rubber bumper is on the rod on each side. Install the diaphragm with the natural bulge to the outside as marked on the diaphragm. Be sure that the large radius side of each plate is toward the diaphragm. Place the sealing washer between the inner diaphragm

plate and the end of the rod. Tighten the plate to approximately 25 ft. lbs. (3.456 pounds/sq. cm.). Torque while allowing the diaphragm to turn freely with the plate.

Hold the opposite side with a wrench on the plate to prevent rotation of the rod. If the opposite chamber is assembled, this will not be necessary.

When reassembling the outer chambers and the manifold, the bolts securing the

manifold ange to the chamber should be snugged prior to tightening the manifold ange. Finish tightening the manifold ange bolts after the chamber bolting is

secured.

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

(see Fig. 9).

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 held in the inner chambers with retaining rings. An o-ring is behind each bushing. If the plunger has any sideways motion check o-rings and bushings for deterioration or wear. 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 intermedi-

Model ET2-M Type 1 Page 6 et2dl2sm-0614

ate. 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 (see Fig. 10 and Fig. 11).

SERVICE INSTRUCTIONS: TROUBLE SHOOTING

1. Pump will not cycle

A. Check to make sure the unit has enough pressure to operate and that the air inlet valve is open. B. Check the discharge line to insure that the discharge line is neither closed nor blocked. C. If the spool in the air distribution valve is not shifting, check the main spool. It must slide freely. D. Excessive air leakage in the pump can prevent cycling. This condition will be evident. Air leakage into the discharge line indicates a ruptured diaphragm. Air leakage from the exhaust port indicates leakage in the air distribution valve. See further service instructions. E. Blockage in the liquid chamber can impede movement of diaphragm.

2. Pump cycles but will not pump

A. Suction side of pump pulling in air. Check the suction line for air leaks and be sure

that the end of the suction line is submerged. Check ange bolting. Check valve anges and manifold to chamber ange joints.

B. Make certain the suction line or strainer is not plugged. Restriction at the suction is indicated by a high vacuum reading when a vacuum gauge is installed in the suction line. C. Check valves may not be seating properly. To check, remove the suction line and

cover the suction port with your hand. If the unit does not pull a good suction (vacuum), the check valves should be inspected for proper seating.

D. Static suction lift may be too high. Priming can be improved by elevating the suction and discharge lines higher than the check valves and pouring liquid into the unit through the suction inlet. When priming at high suction lifts or with long suction lines operate the pump at maximum cycle rate.

E. Incorrect driver uid level or air has not been properly purged.

3. Low performance

A. Capacity is reduced as the discharge pressure increases, as indicated on the performance curve. Performance capability varies with available inlet air supply. Check air pressure at the pump inlet when the pump is operating to make certain that adequate air supply is maintained. B. Check vacuum at the pump suction. Capacity is reduced as vacuum increases. Reduced ow rate due to starved suction will be evident when cycle rate can be varied without change in capacity. This condition will be more prevalent when pumping viscous liquids. When pumping thick, heavy materials the suction line must be kept as large in diameter and as short as possible, to keep suction loss minimal.

C. Low ow rate and slow cycling rate indicate restricted ow through the discharge line. Low ow rate and fast cycling rate indicate restriction in the suction line or air

leakage into suction. D. Unstable cycling indicates improper check valve seating on one chamber. This condition is conrmed when unstable cycling repeats consistently on alternate exhausts. Cycling that is not consistently unstable may indicate partial exhaust restriction due to freezing and thawing of exhaust air. Use of an anti-freeze lubricant in an air line lubricator should solve this problem.

E. Incorrect driver uid level or air has not been properly purged. For additional information, see the Warren Rupp Trouble Shooting Guide.

Repair Parts shown in bold face (darker) type are more likely to need replacement after extended periods of normal use. They are readily available from most Warren Rupp distributors. The pump owner may prefer to maintain a limited inventory of these parts in his own stock to reduce repair downtime to a minimum.

IMPORTANT: When ordering repair parts always furnish pump model number, serial number and type number.

Safety Information

IMPORTANT

Read the safety warnings and instructions in this manual before pump installation and start-up. Failure to comply with the recommendations stated in this manual could damage the pump and void factory warranty.

When the pump is used for materials that tend to settle out

or solidify, the pump should be ushed after each use to

prevent damage. In freezing temperatures the pump should be completely drained between uses.

CAUTION

Before pump operation, inspect all fasteners for loosening

caused by gasket creep. Retighten loose fasteners to prevent leakage. Follow recommended torques stated in this manual.

Nonmetallic pumps and plastic components are not UV stabilized. Ultraviolet radiation can damage these parts and negatively affect material properties. Do not expose to UV light for extended periods of time.

WARNING Pump not designed, tested or certied to be powered by compressed natural gas. Powering the pump with natural gas will void the warranty.

WARNING

When used for toxic or aggressive uids, the pump should always be ushed clean prior to disassembly.

Before maintenance or repair, shut off the compressed air line, bleed the pressure, and disconnect the air line from the pump.

Be certain that approved eye protection and protective clothing are worn at all times. Failure to follow these recommendations may result in serious injury or death.

Airborne particles and loud noise hazards. Wear eye and ear protection.

In the event of diaphragm rupture, pumped material may enter the air end of the pump, and be discharged into the atmosphere. If pumping a product that is hazardous or toxic, the air exhaust

must be piped to an appropriate area for safe containment.

Take action to prevent static sparking. Fire or explosion can

result, especially when handling ammable liquids. The pump, piping, valves, containers and other miscellaneous equipment

must be properly grounded.

This pump is pressurized internally with air pressure during operation. Make certain that all fasteners are in good condition and are reinstalled properly during reassembly.

Use safe practices when lifting

RECYCLING

Many components of SANDPIPER® AODD pumps are made of recyclable materials. We encourage pump users to recycle worn out parts and pumps whenever possible, after any hazard-

ous pumped uids are thoroughly ushed.
