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, disassembling or
servicing your pump.
PRINCIPLE OF PUMP OPERATION
This flap 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
flap-type check valve for each chamber, maintaining flow 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 fittings to a minimum. Do not reduce line size.
For installations of rigid piping, short flexible sections of hose should be
installed between pump and piping. This reduces vibration and strain to the
piping system. A Warren Rupp Tranquilizer
® surge suppressor is recommended
to further reduce pulsation in flow.
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, fill 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 sufficient capacity and pressure required for desired
performance. When the air line is solid piping, use a short length of flexible
hose (not less than ¾" (19mm) in diameter) between pump and piping to
eliminate strain to pipes.

IMPORTANT
Read these safety warnings
and instructions in this
manual completely, before
installation and start-up
of the pump. It is the
responsibility of the purchaser to retain this
manual for reference. Failure to comply with the
recommendations stated in this manual will
damage the pump, and void factory warranty.
Take action to prevent
static sparking. Fire or
explosion can result,
especially when handling
flammable liquids. The pump,
piping, valves, containers or other
miscellaneous equipment must be grounded.
WARNING
Before pump operation,
inspect all gasketed fasteners
for looseness caused by
gasket creep. Re-torque
loose fasteners to prevent leakage. Follow
recommended torques stated in this manual.
CAUTION
Before doing any main-
tenance on the pump, be
certain all pressure is
completely vented from the
pump, suction, discharge,
piping, and all other openings and connections. Be
certain the air supply is locked out or made
non-operational, so that it cannot be started while
work is being done on the pump. Be certain that
approved eye protection and protective clothing are
worn all times in the vicinity of the pump. Failure to
follow these recommendations may result in serious
injury or death.
WARNING
WARNING
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 which is hazardous or toxic, the air exhaust
must be piped to an appropriate area for safe
disposition.
Before maintenance or repair,
shut off the com-pressed air
line, bleed the pressure, and
disconnect the air line
from the pump. The discharge
line may be pressurized
and must be bled of its pressure.
