PRINCIPLE OF PUMP OPERATION
This ball type check valve pump
is powered by compressed air and is
a 1:1 ratio design. The inner side of
one diaphragm chamber is alternately
pressurized while simultaneously
exhausting the other inner chamber.
This causes the diaphragms, which are
connected by a common rod secured by
plates to the centers of the diaphragms,
to move in a reciprocating action. (As
one diaphragm performs the discharge
stroke the other diaphragm is pulled
to perform the suction stroke in the
opposite chamber.) Air pressure is
applied over the entire inner surface of
the diaphragm while liquid is discharged
from the opposite side of the diaphragm.
The diaphragm operates in a balanced
condition during the discharge stroke
which allows the pump to be operated
at discharge heads over 200 feet (61
meters) of water.
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 to maximize
diaphragm life.
Alternate pressurizing and
exhausting of the diaphragm chamber
is performed by an externally mounted,
pilot operated, four way spool type
air distribution valve. When the spool
shifts to one end of the valve body, inlet
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 pressure to the chambers is
reversed. The air distribution valve spool
is moved by a internal pilot valve which
alternately pressurizes one end of the air
distribution valve spool while exhausting
the other end. The pilot valve is shifted
at each end of the diaphragm stroke
when a actuator plunger is contacted
by the diaphragm plate. This actuator
plunger then pushes the end of the pilot
valve spool into position to activate the
air distribution valve.
The chambers are connected with
manifolds with a suction and discharge
check valve for each chamber,
maintaining ow in one direction through
the pump.
INSTALLATION AND START-UP
Locate the pump as close to the
product being pumped as possible. Keep
the suction line length and number of
ttings to a minimum. Do not reduce the
suction line diameter.
For installations of rigid piping, short
sections of flexible conductive hose
should be installed between the pump
and the piping. The exible conductive
hose reduces vibration and strain to the
pumping system. A surge suppressor
is recommended to further reduce
pulsation in ow.
AIR SUPPLY
Air supply pressure cannot exceed
100 psi (7 bar). Connect the pump air
inlet to an air supply of sufcient capacity
and pressure required for desired
performance. When the air supply line
is solid piping, use a short length of
exible conductive hose not less than
1/2" (13mm) in diameter between
the pump and the piping to reduce
strain to the piping. The weight of the
air supply line, regulators and lters
must be supported by some means
other than the air inlet cap. Failure to
provide support for the piping may result
in damage to the pump. A pressure
regulating valve should be installed
to insure air supply pressure does not
exceed recommended limits.
AIR VALVE LUBRICATION
The air distribution valve and the
pilot valve 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 supply. Proper
lubrication requires the use of an air line
lubricator (available from Warren Rupp)
set to deliver one drop of SAE 10 nondetergent oil for every 20 SCFM (9.4
liters/sec.) of air the pump consumes
at the point of operation. Consult the
pump’s published Performance Curve
to determine this.
AIR LINE MOISTURE
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. Water in the air supply can
be reduced by using a point-of-use
air dryer to supplement the user’s air
drying equipment. This device removes
water from the compressed air supply
and alleviates the icing or freezing
problems.
AIR INLET AND PRIMING
To start the pump, open the air
valve approximately 1/2" to 3/4" turn.
After the pump primes, the air valve
can be opened to increase air ow as
desired. If opening the valve increases
cycling rate, but does not increase the
rate of ow, cavitation has occurred.
The valve should be closed slightly to
obtain the most efcient air ow to pump
ow ratio.
BETWEEN USES
When the pump is used for materials
that tend to settle out or solidify when
not in motion, the pump should be
flushed after each use to prevent
damage. (Product remaining in the
pump between uses could dry out or
settle out. This could cause problems
with the diaphragms and check valves
at restart.) In freezing temperatures
the pump must be completely drained
between uses in all cases.

PUMPING HAZARDOUS LIQUIDS
1
When a diaphragm fails, the pumped
liquid or fumes enter the air end of the
pump. Fumes are exhausted into
the surrounding environment. When
pumping hazardous or toxic materials,
the exhaust air must be piped to an
appropriate area for safe disposal. See
illustration #1 at right.
This pump can be submerged if
the pump materials of construction
are compatible with the liquid being
pumped. The air exhaust must be
piped above the liquid level. See
illustration #2 at right. Piping used for
the air exhaust must not be smaller
than 1" (2.54 cm) diameter. Reducing
the pipe size will restrict air ow and
reduce pump performance. When the
pumped product source is at a higher
level than the pump (ooded suction
condition), pipe the exhaust higher than
the product source to prevent siphoning
spills. See illustration #3 at right.
CONVERTING THE PUMP FOR
PIPING THE EXHAUST AIR
The following steps are necessary
to convert the pump to pipe the exhaust
air away from the pump.
Remove the mufer (item 21). The
air distribution valve (item 1) has 1" NPT
threads for piped exhaust.
IMPORTANT INSTALLATION
NOTE: The manufacturer recommends
installing a exible conductive hose
or connection between the pump
and any rigid plumbing. This reduces
stresses on the molded threads of the
air exhaust port. Failure to do so may
result in damage to the air distribution
valve body.
Any piping or hose connected to
the pump’s air exhaust port must be
conductive and physically supported.
Failure to support these connections
could also result in damage to the air
distribution valve body.
