PRINCIPLE OF PUMP OPERATIONThis ball type check valve pumpis powered by compressed air and isa 1:1 ratio design. The inner side ofone diaphragm chamber is alternatelypressurized while simultaneouslyexhausting the other inner chamber.This causes the diaphragms, whichare connected by a common rodsecured by plates to the centers of thediaphragms, to move in a reciprocatingaction. (As one diaphragm performs thedischarge stroke the other diaphragm ispulled to perform the suction stroke inthe opposite chamber.) Air pressure isapplied over the entire inner surface ofthe diaphragm while liquid is dischargedfrom the opposite side of the diaphragm.The diaphragm operates in a balancedcondition during the discharge strokewhich allows the pump to be operatedat discharge heads over 200 feet (61meters) of water.For maximum diaphragm life, keepthe pump as close to the liquid beingpumped as possible. Positive suctionhead in excess of 10 feet of liquid(3.048 meters) may require a backpressure regulating device to maximizediaphragm life.Alternate pressurizing andexhausting of the diaphragm chamberis performed by an externally mounted,pilot operated, four way spool typeair distribution valve. When the spoolshifts to one end of the valve body, inletpressure is applied to one diaphragmchamber and the other diaphragmchamber exhausts. When the spoolshifts to the opposite end of the valvebody, the pressure to the chambersis reversed. The air distribution valvespool is moved by a internal pilot valvewhich alternately pressurizes one endof the air distribution valve spool whileexhausting the other end. The pilot valveis shifted at each end of the diaphragmstroke when a actuator plunger iscontacted by the diaphragm plate. Thisactuator plunger then pushes the endof the pilot valve spool into position toactivate the air distribution valve.The chambers are connected withmanifolds with a suction and dischargecheck valve for each chamber,maintaining flow in one directionthrough the pump.INSTALLATION AND START-UPLocate the pump as close to theproduct being pumped as possible.Keep the suction line length andnumber of fittings to a minimum. Do notreduce the suction line diameter.For installations of rigid piping,short sections of flexible hose shouldbe installed between the pumpand the piping. The flexible hosereduces vibration and strain to thepumping system. A surge suppressoris recommended to further reducepulsation in flow.AIR SUPPLYAir supply pressure cannot exceed100 psi (7 bar). Connect the pumpair inlet to an air supply of sufficientcapacity and pressure required fordesired performance. When the airsupply line is solid piping, use a shortlength of flexible hose not less than1/2" (13mm) in diameter betweenthe pump and the piping to reducestrain to the piping. The weight of theair supply line, regulators and filtersmust be supported by some meansother than the air inlet cap. Failure toprovide support for the piping may resultin damage to the pump. A pressureregulating valve should be installedto insure air supply pressure does notexceed recommended limits.AIR VALVE LUBRICATIONThe air distribution valve and thepilot valve are designed to operateWITHOUT lubrication. This is thepreferred mode of operation. There maybe instances of personal preferenceor poor quality air supplies whenlubrication of the compressed airsupply is required. The pump air systemwill operate with properly lubricatedcompressed air supply. Properlubrication requires the use of an air linelubricator (available from Warren Rupp)set to deliver one drop of SAE 10 nondetergentoil for every 20 SCFM (9.4liters/sec.) of air the pump consumesat the point of operation. Consult thepump’s published Performance Curveto determine this.AIR LINE MOISTUREWater in the compressed air supplycan create problems such as icing orfreezing of the exhaust air, causingthe pump to cycle erratically or stopoperating. Water in the air supply canbe reduced by using a point-of-useair dryer to supplement the user’s airdrying equipment. This device removeswater from the compressed air supplyand alleviates the icing or freezingproblems.AIR INLET AND PRIMINGTo start the pump, open the air valveapproximately 1/2" to 3/4" turn. Afterthe pump primes, the air valve can beopened to increase air flow as desired.If opening the valve increases cyclingrate, but does not increase the rate offlow, cavitation has occurred. The valveshould be closed slightly to obtain themost efficient air flow to pump flow ratio.BETWEEN USESWhen the pump is used for materialsthat tend to settle out or solidify whennot in motion, the pump should beflushed after each use to preventdamage. (Product remaining in thepump between uses could dry out orsettle out. This could cause problemswith the diaphragms and check valvesat restart.) In freezing temperaturesthe pump must be completely drainedbetween uses in all cases.m07nmdl1sm-rev0513 Models M07 Non-Metallic Page 7

Solenoid Shifted AirDistribution Valve OptionWarren Rupp’s solenoid shifted,air distribution valve option utilizeselectrical signals to precisely controlyour SANDPIPER’s speed. Thesolenoid coil is connected to a customer- supplied control. Compressed airprovides the pumping power, whileelectrical signals control pump speed(pumping rate).Solenoid ConnectorBefore wiring, removeterminal block fromconduit connector.WiringDiagram#2 Terminal Neutral(Negative)#1 TerminalPower(Positive)3rd Terminal forground.OperationThe Solenoid Shifted SANDPIPER has asolenoid operated, air distribution valvein place of the standard SANDPIPER’spilot operated, air distribution valve.Where a pilot valve is normally utilizedto cycle the pump’s air distributionvalve, an electric solenoid is utilized.As the solenoid is powered, one of thepump’s air chambers is pressurizedwhile the other chamber is exhausted.When electric power is turned off, thesolenoid shifts and the pressurizedchamber is exhausted while the otherchamber is pressurized. By alternatelyapplying and removing power to thesolenoid, the pump cycles much like astandard SANDPIPER pump, with oneexception. This option provides a wayto precisely control and monitor pumpspeed.To ControlBefore InstallationBefore wiring the solenoid, makecertain it is compatible with your systemvoltage.m07nmdl1sm-rev0513 Models M07 Non-Metallic Page 20

DIAPHRAGM SERVICINGTo service the diaphragms firstshut off the suction, then shut off thedischarge lines to the pump. Shutoff the compressed air supply, bleedthe pressure from the pump, anddisconnect the air supply line from thepump. Drain any remaining liquid fromthe pump.Step #1: See the pump compositerepair parts drawing, and the diaphragmservicing illustration.Using a 1/2" wrench or socket,remove the 16 capscrews (items 9 &10), and nuts that fasten the elbows(items 16) to the outer chambers(items 13). Remove the elbows with themanifolds and spacers attached.Step #2: Removing the outerchambers.Using a 1/2" wrench or socket,remove the 16 capscrews (items9 and 11), and nuts that fasten theouter chambers, diaphragms, andintermediate bracket (item 4) together.Step #3: Removing the diaphragmassemblies.Use a 3/4" wrench or six pointedsocket to remove the diaphragmassemblies (outer plate, diaphragm,and inner plate) from the diaphragm rod(item 30) by turning counterclockwise.Insert a 6-32 set screw into thesmaller tapped hole in the innerdiaphragm plate (item 26). Insertthe protruding stud and the 6-32fastener loosely into a vise. Use a3/4" wrench or socket to remove theouter diaphragm plate (item 25) byturning counterclockwise. Inspect thediaphragm (item 14) for cuts, punctures,abrasive wear or chemical attack.Replace the diaphragms if necessary.Step #4: Installing the diaphragms.Push the threaded stud of the outerdiaphragm plate through the centerhole of the diaphragm. Thread the innerplate clockwise onto the stud. Use atorque wrench to tighten the diaphragmassembly together to 90 in lbs.(10.17 Newton meters) 120 in lbsSantoprene (13.56 Newton meters).Allow a minimum of 15 minutes toelapse after torquing, then re-torquethe assembly to compensate for stressrelaxation in the clamped assembly.Step #5: Installing the diaphragmassemblies to the pump.Make sure the bumper (item 6) isinstalled over the diaphragm rod.Thread the stud of the one diaphragmassembly clockwise into the tappedhole at the end of the diaphragm rod(item 30) until the inner diaphragm plateis flush to the end of the rod. Insert rodinto pump.Align the bolt holes in the diaphragmwith the bolt pattern in the intermediatebracket (item 4). Make sure the moldeddirectional arrows on the diaphragmpoint vertically.Fasten the outer chamber (item 13)to the pump, using the capscrews (items9 & 11), hex nuts and flat washers.On the opposite side of the pump,pull the diaphragm rod out as faras possible. Make sure the bumper(item 6) is installed over thediaphragm rod.Thread the stud of the remainingdiaphragm assembly clockwise into thetapped hole at the end of the diaphragmrod (item 30) as far as possible and stillallow for alignment of the bolt holesin the diaphragm with the bolt patternin the inner chamber. The moldeddirectional arrows on the diaphragmmust point vertically.Fasten the remaining outer chamber(item 13) to the pump, using thecapscrews (items 9 and 11) and hexnuts.Step #6: Re-install the elbow/spacer/manifold assemblies to thepump, using the capscrews (items 9 &10) and hex nuts.The pump is now ready to bere-installed, connected and returned tooperation.OVERLAY DIAPHRAGM SERVICINGThe PTFE overlay diaphragm(item 15) is designed to fit snuglyover the exterior of the standard TPEdiaphragm (item 14).The molded directional arrowson the overlay diaphragm must pointvertically.Follow the same proceduresdescribed for the standard diaphragmfor removal and installation.Follow the same proceduresdescribed for the standard diaphragmfor removal and installation.

PUMPING HAZARDOUS LIQUIDSWhen a diaphragm fails, the pumpedliquid or fumes enter the air end of thepump. Fumes are exhausted intothe surrounding environment. Whenpumping hazardous or toxic materials,the exhaust air must be piped to anappropriate area for safe disposal. Seeillustration #1 at right.This pump can be submerged ifthe pump materials of constructionare compatible with the liquid beingpumped. The air exhaust must bepiped above the liquid level. Seeillustration #2 at right. Piping used forthe air exhaust must not be smallerthan 1/2" (1.27 cm) diameter. Reducingthe pipe size will restrict air flow andreduce pump performance. When thepumped product source is at a higherlevel than the pump (flooded suctioncondition), pipe the exhaust higher thanthe product source to prevent siphoningspills. See illustration #3 at right.IMPORTANT INSTALLATION NOTE:The manufacturer recommendsinstalling a flexible hose or connectionbetween the pump and any rigid plumbing.This reduces stresses on the moldedplastic threads of the air exhaust port.Failure to do so may result in damage tothe air distribution valve body.Any piping or hose connectedto the pump’s air exhaust port mustbe physically supported. Failure tosupport these connections could alsoresult in damage to the air distributionvalve body.Exhaust Conversion DrawingCONVERTED EXHAUST ILLUSTRATIONPUMP INSTALLATION AREA1" DIAMETER AIREXHAUST PIPINGIllustration #1LIQUIDLEVELSUCTIONLINESAFE AIREXHAUSTDISPOSALAREAMUFFLERMUFFLER1" DIAMETER AIREXHAUST PIPINGConverting the pump forpiping the exhaust airThe following steps are necessaryto convert the pump to pipe the exhaustair away from the pump.Use a Phillips screwdriver toremove the four self-tapping screws(item 1-H).Remove the muffler cap and muffler(items 1-G and 1-F).
