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 used for toxic or aggressive uids, the pump should
always be ushed clean prior to disassembly.
Airborne particles and loud noise hazards. Wear eye and ear
protection.
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.
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.
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.
CAUTION
WARNING
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.
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.
This pump is pressurized internally with air pressure
during operation. Make certain that all fasteners and piping
connections are in good condition and are reinstalled properly
during reassembly.
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.

WARNING
Pump not designed, tested or certied to be powered by
compressed natural gas. Powering the pump with natural
gas will void the warranty.
Use safe practices when lifting

8 • Model PB¼ Non-Metallic
Air-Operated Double Diaphragm (AODD) pumps are powered
by compressed air or nitrogen.
The main directional (air) control valve ①distributes
compressed air to an air chamber, exerting uniform pressure
over the inner surface of the diaphragm
②. At the same time,
the exhausting air ③ from behind the opposite diaphragm
is directed through the air valve assembly(s) to an exhaust
port ④.
As inner chamber pressure (P1) exceeds liquid chamber
pressure (P2), the rod ⑤connected diaphragms shift
together creating discharge on one side and suction on the
opposite side. The discharged and primed liquid’s directions
are controlled by the check valves (ball or ap)⑥orientation.
The pump primes as a result of the suction stroke. The
suction stroke lowers the chamber pressure (P3) increasing
the chamber volume. This results in a pressure differential
necessary for atmospheric pressure (P4) to push the uid
through the suction piping and across the suction side check
valve and into the outer uid chamber ⑦.
Suction (side) stroking also initiates the reciprocating
(shifting, stroking or cycling) action of the pump. The suction
diaphragm’s movement is mechanically pulled through its
stroke. The diaphragm’s inner plate makes contact with an
actuator plunger aligned to shift the pilot signaling valve.
Once actuated, the pilot valve sends a pressure signal to the
opposite end of the main directional air valve, redirecting the
compressed air to the opposite inner chamber.

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. 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.

Principle of Pump Operation
SUBMERGED ILLUSTRATION
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.
Air Supply
Connect the pump air inlet to an air supply with sufcient capacity and pressure to achieve desired performance. A pressure regulating valve should be installed to
insure air supply pressure does not exceed recommended limits.
Air Valve Lubrication
The air distribution system is designed to operate WITHOUT lubrication. This is the standard mode of operation. If lubrication is desired, install an air line lubricator
set to deliver one drop of SAE 10 non-detergent oil for every 20 SCFM (9.4 liters/sec.) of air the pump consumes. Consult the Performance Curve to determine air
consumption.
Air Line Moisture
Water in the compressed air supply may cause 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.
Air Inlet And Priming
To start the pump, slightly open the air shut-off valve. 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.

Diaphragm Servicing
Step 1: Remove the two V-Band clamps securing the outer chambers to
the intermediate housing.
Step 2: Remove the diaphragm assembly (outer plate, diaphragm,
spacer gasket (for PFTE units only, inner plate) by turning the assembly
counterclockwise using a 1/2" (1.27 cm) wrench on the outer plate lugs. (If
a socket is used, it must be a six-point socket.) The interior components
consisting of the shaft seal and pilot valve assembly are now accessible
for service.
Step 3: Procedures for reassembling the diaphragms are the reverse of
the above. Install the diaphragm with the natural bulge outward.
Step 4: Install the outer diaphragm plate on the outside of the diaphragm
and make certain that the large radius side of the inner plate is toward the
diaphragm.
Step 5: Tighten the outer diaphragm plate to approximately 30 in./lbs.
(3.39 Newton meters). Torque while allowing the diaphragm to turn freely
with plates. Use a wrench on the outer diaphragm plate of the opposite
side to keep rod from rotating. If the opposite chamber is assembled, the
rod need not be held.
Diaphragm Rod Seals Servicing
Step 1: To service the rod seals rst remove pilot valve, then remove the
inserts on each of the intermediate brackets by prying them out with a
small at screwdriver.
Step 2: After removing the inserts take the K-R rod seals out of the inserts
and replace.
Step 3: When reinstalling the seals, make sure the open side of the seals
face into thecounterbore in the inserts.
Step 4: To install the inserts into intermediate bracket, simply press the
insert into the counterbore in each of the intermediate bracket, making
sure that the closed side of insert faces out. The inserts should be ush to
the surface of the intermediate bracket or slightly below the surface when
fully installed.
