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 certied 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.
WARNING
The use of non-OEM replacement parts will void (or negate)
agency certications, including CE, ATEX, CSA, 3A and EC1935
compliance (Food Contact Materials). Warren Rupp, Inc. cannot
ensure nor warrant non-OEM parts to meet the stringent
requirements of the certifying agencies.
Grounding ATEX Pumps
ATEX compliant pumps are suitable for use in explosive atmospheres when the equipment is properly grounded
in accordance with local electrical codes. Pumps equipped with electrically conductive diaphragms are suitable for
the transfer of conductive or non-conductive uids of any explosion group. When operating pumps equipped with
non-conductive diaphragms that exceed the maximum permissible projected area, as dened in EN 13461-1: 2009
section 6.7.5 table 9, the following protection methods must be applied:
• Equipment is always used to transfer electrically conductive uids or
• Explosive environment is prevented from entering the internal portions of the pump, i.e. dry running
For further guidance on ATEX applications, please consult the factory.

PLEASE NOTE!
The photos shown in this manual are for general instruction only. YOUR SPECIFIC
MODEL MAY NOT BE SHOWN. Always refer to the parts list and exploded view
drawing for your specific model when installing, disasembling or servicing
your pump.
PRINCIPLE OF PUMP OPERATION
This ball check valve pump is powered by compressed air and is a 1:1 pressure ratio
design. The pump is alternately pressurize through the inner side of one diaphragm
chamber, while simultaneously exhausting the other inner chamber. Air pressure
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, and the unit can be operated at discharge heads over
200 feet (61 meters) of water head.
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 air. 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 spool. This pushes the pilot valve into
position for shifting of the air distribution valve.
The chambers are manifolded together with a suction and discharge check valve
for each chamber which maintains ow in one direction through the pump.
INSTALLATION & START-UP
Locate the pump as close to the product being pumped as possible. Keep 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.

pulsation in ow.
This pump was tested at the factory prior to shipment and is ready for operation.
It is 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.

surge suppressor is recommended to further reduce
AIR SUPPLY
Air supply pressures cannot exceed 125 psi (8.61 bar). Connect the pump air inlet
to an air supply of sufcient 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.
