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 simultane ously
exhausting the other inner chamber. This
causes the diaphragms, which are
connected by a common rod secured
by plate s to the ce nte rs 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
regul ati ng device to max imi ze
diaphragm life.
Alter nat e p res surizing 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 dis tribution val ve sp ool 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 flow 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
fittings to a minimum. Do not reduce the
suction line diameter.
For installations of rigid piping, short
sections of flexible hose should be
installed between the pump and the
piping. The f lexi ble hose reduces
vibration and strain to the pumping
syste m. A su rge suppressor is
recom men ded to f urth er reduce
pulsation in flow.
AIR SUPPLY
Air supply pressure cannot exceed
100 psi (7 bar). Connect the pump air
inlet to an air supply of sufficient
capacity and pressure required for
desired perfor mance. When the air
supply line is solid piping, use a short
length of flexible hose not less than ½"
(13mm) in diameter between the pump
and the piping to reduce strain to the
piping. The weight of the air supply line,
regulators and filters 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
suppl ies whe n lubricatio n 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 set to
deliv er one drop of S AE 10
non-detergent oil for every 20 SCFM
(9.4 liters/sec.) of air the pump
consumes at the point of operation.
Consu lt the pump ’s publ ish ed
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 er raticall y 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 ½ to ¾ turn. After the
pump primes, the air valve can be
opened to increase air flow as desired.
If opening the valve increases cycling
rate, but does not increase the rate of
flow, cavitation has occurred. The valve
should be closed slightly to obtain the
most efficient air flow to pump flow 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
tempe rat ure s the pump must b e
completely drained between uses in all
cases.

FOR VIRG IN PTFE EQUIP PED
PUMPS CONCEPT
The spill prevention option prevents
the air end components from being
contaminated or damaged when a
pumping diaphragm ruptures while
pumping caustic or toxic materials. It
also helps to protect the environment.
With the installation of optional leak
detec tor s (either mech ani cal or
electronic) the diaphragm rupture can be
detected. The pump can then be shut
down and repaired before any caustic or
toxic materials can enter the air end and
be exhausted into the surrounding
environment.
OPTION DIAPHRAGM SERVICING
To service the diaphragms first shut
of f the suction, then shut off the
discharge lines to the pump. Next shut
off the compressed air supply, bleed the
pressure from the pump, and disconnect
the air supply line from the pump. Drain
any remaining pumped liquid from the
pump. Re mov e the pump bef ore
servicing.
Next, drain the fluid from the spill
prevention chambers. This can be done
by removing the bottom plug (item 50)
from each spill prevention chamber.
After t he fluid from the spil l
prevention chambers has been drained,
the wet end components can now be
removed. See diaphragm servicing
section for detailed instructions. The spill
prevention option has two additional
virgin PTFE pumping diaphragms (item
46).
FILLING CHAMBERS WITH LIQUID
THE CHAMBERS ARE FILLED
WITH WATER AT THE FACTORY.
If you prefer to substitute another
liquid, to prevent system contamination
consult the factory first to determine
compatibility of the substitute with pump
construction.
Follow the steps listed here to replace
the liquid in the pump after disassembly
or liquid loss:
1. Dra in the flu id i n the spil l
prevention chambers by removing the
bottom two boss plugs (items 50).
Replace the bottom two boss plugs after
the fluid is drained.
2. Remove the eight capscrews (item
11) fastening the discharge manifold and
elbows to the outer chambers (items 15).
The discharge manifolds and elbows can
now be removed.
3. Remove the top two boss plugs
(item s 50). T he spill prevent ion
chambers are filled through the exposed
ports.
4. Apply air pressure to the air
distribution valve. Install safety clip
(item 1-F) into the smaller unthreaded
hole in one end cap. This locks the valve
spool to one side, keeping the pump
from shifting.
5. Face the side of the pump with
the installed safety clip. If the safety clip
is installed in the top end cap, fill the left
spill containment chamber. If the safety
clip is installed on the bottom end cap,
fill the right spill prevention chamber. The
volume of fluid is 3770 ml (127.5 fl. oz.).
It is important that the exact amount
of fluid is used. Too little or too much
fluid causes premature diaphragm
failure and erratic pumping.
6. Loosely reinstall one boss plug
to the filled spill prevention chamber.
7. Shut off air supply. Remove safety
clip. Adjust the air line regulator so that
air pressure slowly fills the pump. The
diaphragm expands, forcing the fluid in
the chamber to be slowly displaced.
When the pump shifts to the opposite
side, quickly install the safety clip.
8. Loosen the top boss plug on the
filled chambers. This allows fluid in the
chamber to purge trapped air from the
chamber. This can be seen by watching
the column of fluid in the sight tube. When
fluid appears at the top of the port,
quickly tighten the boss plug. Fluid loss
of 1 to 2ml is acceptable.
9. Tilt the pump so the uppermost
pipe tee (item 53) is in the ver tical
position. Loosen the pipe plug (item 49).
This will allow trapped air to purge
through the pipe tee. When fluid appears
at the tee opening, reinstall the pipe
plug.
NOTE: If all air is not purged using
this procedure, remove the check valve
components from the top port of the outer
chamber (item 15). Apply manual
pressure to the pumping diaphragm by
inserting a blunt instrument into the top
port of the outer chamber and applying
pressure to the diaphragm. Loosen the
pipe plug (item 49) allowing the fluid to
pu rge any remaining trapped air.
Reinstall the plug.
10. Repeat steps 5 through 9 to fill
opposite spill prevention chamber.
11. Reins tal l th e ch eck val ve
components, discharge manifold and
elbows to the pump. The pump is now
ready for operation.
IMPORTANT
Read these instructions
completely, before installation and start-up. It
is the responsibility of
the purchaser to retain
this manual for reference. Fa ilure to
comply with the recommendations stated
in this manual will damage the pump, and
void factory warranty.

SOLEN OID SHIFT ED AIR
DISTRIBUTION VALVE OPTION
The solenoid shifted, air distribution
valve option utilizes electrical signals
to precisely control your pump’s speed.
The solenoid coil is connected to a
custo mer - sup pli ed control.
Compressed air provides the pumping
power, while electrical signals control
pump speed (pumping rate).
OPERATION
The Solenoid Shifted pump has a
solenoid operated, air distribution valve
in place of the standard pump’s pilot
operated, air distribution valve. Where
a pilot valve is normally utilized to
cycle the pump’s air distribution valve,
an electric solenoid is utilized. As the
solenoid is powered, one of the pump’s
air chambers is pressurized while the
other chamber is exhausted. When
elect ric pow er i s tu rned off, the
solenoid shifts and the pressurized
chamber is exhausted while the other
chamber is pressurized. By alternately
applying and removing power to the
solenoid, the pump cycles much like a
standard pump, with one exception. This
option provides a way to precisely
control and monitor pump speed.
Solenoid Connector
Before wiring,
remove terminal
block from conduit
connector.

PUMPING HAZARDOUS LIQUIDS
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
ha zardous or toxic material s, the
exhau st air mus t be pi ped 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
no t b e s maller than 1" (2.54 c m)
diameter. Reducing the pipe size will
restrict air flow and reduce pump
performance. When the pumped product
source is at a higher level than the pump
(flooded suction condition), pipe the
exhaust higher than the product source
to p rev ent sip hon ing spills. See
illustration #3 at right.
IMPORTAN T INS TALLATI ON
NOTE: The manufacturer recommends
installing a flexible hose or connection
betwe en th e pump a nd an y rigid
plumbing. This reduces stresses on the
molded plastic 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 exh aust por t must be
physically supported. Failure to support
these connections could also result in
damage to the air distribution valve body.

9
/16" wrench or socket to remove the
fasteners. Once the elbows are removed,
the modular check valves can be seen
in the cavities of the outer chamber
(items 15).
Next remove the check valve seal
(item 37). Inspect the seal for cuts or
pinched areas. Replace seal as needed.
Disassemble the component parts of
each modular check valve. Inspect the
check valve retainer (item 32) for cuts,
abrasive wear, or embedded materials.
Replace as needed.
Inspect the check balls (items 3) for
wear, abrasion, or cuts on the spherical
surface. The check valve seats (items
38) should be inspected for cuts,
abrasive wear, or embedded material on
the surfaces of both the external and
internal chamfers. The spherical surface
of the check balls must seat flush to
the surface of the inner chamfer on the
check valve seats for the pump to
operate to peak efficiency. Replace any
worn or damaged parts as necessary.
Remove the remaining check valve
seal (item 37). Inspect the seal for cuts
or pinched areas. Replace seal as
needed.
Re-assemble the modular check
valve. The seat should fit snugly into the
retainer.
Place a check valve seal (item 37)
into the cavity of the outer chamber (item
15). Make sure the chamfer side of the
seal faces out. Insert the modular check
valve into the outer chamber with the
retainer facing up. Install a check valve
seal (item 37). Make sure the chamfer
side of the seal faces the chamfer on
the check valve seat or retainer.
