PRINCIPLE OF PUMP OPERATIONThis ball type check valve pump is
powered by compressed air and is a 1:1ratio design. The inner side of onediaphragm chamber is alternatelypressurized while simultaneouslyexhausting the other inner chamber. Thiscauses the diaphragms, which areconnected by a common rod securedby plates to the centers of thediaphragms, to move in a reciprocatingaction. (As one diaphragm performs thedischarge stroke the other diaphragmis pulled to perform the suction strokein the opposite chamber.) Air pressureis applied over the entire inner surfaceof the diaphragm while liquid isdischarged from the opposite side of thediaphragm. The diaphragm operates ina balanced condition during thedischarge stroke which allows the pumpto be operated at discharge heads over200 feet (61 meters) 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 (3.048meters) may require a back pressureregulating device to maximizediaphragm life.
Alternate pressurizing andexhausting of the diaphragm chamberis performed by an externally mounted,pilot operated, four way spool type airdistribution valve. When the spool shiftsto one end of the valve body, inletpressure is applied to one diaphragmchamber and the other diaphragmchamber exhausts. When the spool
shifts to the opposite end of the valvebody, the pressure to the chambers isreversed. The air distribution valve spoolis moved by a internal pilot valve whichalternately pressurizes one end of theair 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 end ofthe 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 direction throughthe pump.
INSTALLATION AND START-UPLocate the pump as close to the
product being pumped as possible. Keepthe suction line length and number offittings to a minimum. Do not reduce thesuction line diameter.
For installations of rigid piping, shortsections of flexible hose should beinstalled between the pump and thepiping. The flexible hose reducesvibration and strain to the pumpingsystem. A Warren Rupp Tranquilizer®
surge suppressor is recommended tofurther reduce pulsation in flow.
AIR SUPPLYAir supply pressure cannot exceed
125 psi (8.6 bar). Connect the pump airinlet to an air supply of sufficientcapacity and pressure required fordesired performance. When the air
supply line is solid piping, use a shortlength of flexible hose not less than ½"(13mm) in diameter between the pumpand the piping to reduce strain to thepiping. The weight of the air supply line,regulators and filters must be supportedby some means other than the air inletcap. Failure to provide support for thepiping may result in damage to thepump. A pressure regulating valveshould be installed to insure air supplypressure does not exceed recommendedlimits.
AIR VALVE LUBRICATIONThe air distribution valve and the pilot
valve are designed to operate WITHOUTlubrication. This is the preferred modeof operation. There may be instances ofpersonal preference or poor quality airsupplies when lubrication of thecompressed air supply is required. Thepump air system will operate withproperly lubricated compressed airsupply. Proper lubrication requires theuse of an air line lubricator (available fromWarren Rupp) set to deliver one drop ofSAE 10 non-detergent oil for every 20SCFM (9.4 liters/sec.) of air the pumpconsumes at the point of operation.Consult the pump’s publishedPerformance Curve to determine this.
AIR LINE MOISTUREWater in the compressed air supply
can create problems such as icing orfreezing of the exhaust air, causing thepump to cycle erratically or stopoperating. Water in the air supply can bereduced by using a point-of-use air dryer
to supplement the user’s air dryingequipment. This device removes waterfrom the compressed air supply andalleviates the icing or freezing problems.
AIR INLET AND PRIMINGTo start the pump, open the air valve
approximately ½ to ¾ turn. After thepump 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 materials
that tend to settle out or solidify whennot in motion, the pump should be flushedafter each use to prevent damage.(Product remaining in the pump betweenuses could dry out or settle out. This couldcause problems with the diaphragms andcheck valves at restart.) In freezingtemperatures the pump must becompletely drained between uses in allcases.

TROUBLESHOOTINGPossible Symptoms:• Pump will not cycle.• Pump cycles, but produces no flow.• Pump cycles, but flow rate is
unsatisfactory.• Pump cycle seems unbalanced.• Pump cycle seems to produce
excessive vibration.
What to Check: Excessive suction liftin system.Corrective Action: For lifts exceeding20 feet (6 meters), filling the pumpingchambers with liquid will prime the pumpin most cases.
What to Check: Excessive floodedsuction in system.Corrective Action: For floodedconditions exceeding 10 feet (3 meters)of liquid, install a back pressure device.
What to Check: System head exceedsair supply pressure.Corrective Action: Increase the inlet airpressure to the pump. Most diaphragmpumps are designed for 1:1 pressureratio at zero flow.
What to Check: Air supply pressure orvolume exceeds system head.Corrective Action: Decrease inlet airpressure and volume to the pump ascalculated on the publishedPERFORMANCE CURVE. Pump iscavitating the fluid by fast cycling.
What to Check: Undersized suction line.Corrective Action: Meet or exceedpump connection recommendationsshown on the DIMENSIONALDRAWING.

SOLENOID SHIFTED AIRDISTRIBUTION VALVE OPTIONWarren Rupp’s solenoid shifted, airdistribution valve option utilizes electricalsignals to precisely control yourSANDPIPER’s speed. The solenoid coilis connected to a customer - suppliedcontrol. Compressed air provides thepumping power, while electrical signalscontrol pump speed (pumping rate).
OPERATIONThe Solenoid Shifted SANDPIPER hasa solenoid 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 distribution valve,an electric solenoid is utilized. As thesolenoid is powered, one of the pump’sair chambers is pressurized while theother chamber is exhausted. Whenelectric power is turned off, the solenoidshifts and the pressurized chamber isexhausted while the other chamber ispressurized. By alternately applying andremoving power to the solenoid, thepump cycles much like a standardSANDPIPER pump, with one exception.This option provides a way to preciselycontrol and monitor pump speed.
BEFORE INSTALLATIONBefore wiring the solenoid, make certainit is compatible with your systemvoltage.

PUMPING HAZARDOUS LIQUIDSWhen a diaphragm fails, the pumped
liquid or fumes enter the air end of thepump. Fumes are exhausted into thesurrounding environment. When pumpinghazardous or toxic materials, theexhaust air must be piped to anappropriate area for safe disposal. Seeillustration #1 at right.
This pump can be submerged if thepump materials of construction arecompatible with the liquid being pumped.The air exhaust must be piped abovethe liquid level. See illustration #2 atright. Piping used for the air exhaust mustnot be smaller than 1" (2.54 cm)diameter. Reducing the pipe size willrestrict air flow and reduce pumpperformance. When the pumped productsource is at a higher level than the pump(flooded suction condition), pipe theexhaust higher than the product sourceto prevent siphoning spills. Seeillustration #3 at right.
CONVERTING THE PUMP FORPIPING THE EXHAUST AIR
The following steps are necessary toconvert the pump to pipe the exhaustair away from the pump.
Remove the muffler (item 36). Theair distribution valve (item 1) has 1" NPTthreads for piped exhaust.
IMPORTANT INSTALLATIONNOTE: The manufacturer recommendsinstalling a flexible conductive hose orconnection between the pump and anyrigid plumbing. This reduces stresses onthe molded threads of the air exhaustport. Failure to do so may result indamage to the air distribution valve body.
Any piping or hose connected to the pump’s air exhaust port must beconductive and physically supported.Failure to support these connectionscould also result in damage to the airdistribution valve body.
