CAUTIONS - READ FIRST
CAUTION: Do not apply compressed air to the
exhaust port – pump will not function.
CAUTION: Do not over-lubricate air supply – excess
lubrication will reduce pump performance. Pump is
pre-lubed.
TEMPERATURE LIMITS:
Neoprene -17.7°C to 93.3°C 0°F to 200°F
Buna-N -12.2°C to 82.2°C 10°F to 180°F
EPDM -15.1°C to 137.8°C -60°F to 280°F
Viton -40°C to 176°C -40°F to 350°F
Santoprene -40°C to 107°C -40°F To 225°F
PTFE -4°C to 104°C 40°F to 220°F
Polypropylene 0°C to 79°C 32°F to 175°F
CAUTION: Check temperature limits for all wetted
components. Example: Viton®has a maximum
limit of 176.7°C (350°F) but polypropylene has a
maximum limit of only 79°C (175°F).
CAUTION: Maximum temperature limit are based
upon mechanical stress only. Certain chemicals
will signicantly reduce maximum safe operating
temperatures.
WARNING:Prevention of static parking – if static
sparking occurs, re or explosion could result.
Pump, valves, and containers must be grounded to
a proper grounding point when handling ammable
uids and whenever discharge of static electricity
is a hazard.
CAUTION: Do not exceed 8.6 bar (125psig) air
supply pressure.
CAUTION: The process uid and cleaning uids
must be chemically compatible with all wetted
pump components.
CAUTION: Do not exceed 79°C (174°F) air inlet
temperature.
CAUTION: Pumps should be thoroughly ushed
before installing into process lines.
CAUTION: Always wear safety glasses when
operating pump. If diaphragm rupture occurs,
material being pumped may be forced out air
exhaust.
CAUTION: Before any maintenance or repair is
attempted, the compressed air line to the pump
should be disconnected and all air pressure
allowed to bleed from pump. Disconnect all intake,
discharge and air lines. Drain the pump by turning
it upside down and allowing any uid to ow into a
suitable container.
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to pump to make sure all pipeline
debris is clear. Use an in-line air lter. A 5µ (micron)
air lter is recommended.
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure a tight t.
(See torque specications.)
NOTE: Before starting disassembly, mark a line
from each liquid chamber to its corresponding air
chamber. This line will assist in proper alignment
during reassembly.
CAUTION: Tighten all hardware prior to installation.
CAUTION: 1/4” pump is not submersible

How It Works - Pump
1. Air Chamber
The air chamber is the chamber that houses
the air which powers the diaphragms.
2. Air Distribution System
The air distribution system is the heart of
the pump. The air distribution system is the
mechanism that shifts the pump in order to
create suction and discharge strokes.
3. Lock Nut (Outer Diaphragm Piston)
The outer diaphragm pistons provide a
means to connect the diaphragms to the
reciprocating common shaft and to seal the
liquid side from the air side of the diaphragm.
4. Holding plate (Inner Diaphragm Piston)
The inner piston is located on the air side of
the pump and does not come into contact
with the process uid.
5. Check Valve Ball
NOMAD air-operated pumps use suction and
discharge check valves to produce directional
ow of process uid in the liquid chamber.
The check valve balls seal and release on the
check valve seats allowing for discharge and
suction of process uid to occur.
6. Check Valve Seat
The removable seats provide the ball valves a
site to check.
7. Discharge Manifold
Process uid exits the pump from the
discharge port located on the discharge
manifold at the top of the pump.
8. Liquid Chamber
The liquid chamber is lled with the process
uid during the suction stroke and is emptied
during the discharge stroke. It is separated
from the compressed air by the diaphragms.
9. Diaphragm
The diaphragm membrane provides for
separation of the process uid and the
compressed air power source. To perform
adequately, diaphragms should be of
sufcient thickness and of appropriate
material to prevent degradation or permeation
in specic process uid applications. TABLA
offers a variety of diaphragm materials for
your specic application requirements.
10. Inlet Manifold
Process uid enters the pump from the intake
port located on the inlet manifold at the
bottom of the pump.
The NOMAD diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show ow pattern through the pump
upon its initial stroke. It is assumed the pump has no uid in it prior to its initial stroke.

Suggested Installation
INSTALLATION:
• Suction pipe equal to/greater than pump
diameter (same for discharge)
• Tighten all fasteners before use
• Suction connection should be non-collapsible
AIR SUPPLY:
• Air line size must be large enough to create
desired volume (see performance curve
section)
• Do not exceed 8.6 BAR (125 PSIG)
• For best results, use 5 micron air lter
PIPING:
• Remove as many turns/elbows as possible
• Piping should be supported
• Flexible hose will avoid stress on pump tting
• Gate Valve should be used in applications
involving ooded suction
• In positive suction head conditions, limit
inlet pressure to 0.5 - 0.7 BAR (7 - 10 PSI).
Premature diaphragm failure will take place
above the parameters.
ALL NOMAD PUMPS ARE CAPABLE OF PASSING
SOLIDS. A STRAINER SHOULD BE USED ON
THE PUMP INTAKE TO ENSURE THAT THE
PUMP’S RATED SOLIDS CAPACITY IS NOT
EXCEEDED.
CAUTION: DO NOT EXCEED 8.6 BAR (125 PSIG)
AIR SUPPLY PRESSURE.

Suggested Installation
This illustration is a generic
representation of an air-operated
double-diaphragm pump.
NOTE: In the event of a power failure, the shut off valve should be
closed, if the restarting of the pump is not desirable once power is
regained.
AIR OPERATED PUMPS: To stop the pump from operating in an
emergency situation, simply shut off valve (user supplied) installed
in the air supply line. A properly functioning valve will stop the air
supply to the pump, therefore stopping output. The shut off valve
should be located far enough away from the pumping equipment
such that it can be reached safely in an emergency situation.

9
Suggested Operation & Maintenance
Pump will not run or runs slowly.
1. Ensure that the air inlet pressure is at least 0.4
Bar (5 psig) above start up pressure and that the
differential pressure (the difference between air
inlet and liquid discharge pressures) is not less
than 0.7 Bar (10 psig).
2. Check air inlet lter for debris
3. Check for extreme air leakage (blow by) which
would indicate worn seals/bores in the air valve.
4. Disassemble pump and check for obstructions
in the air passageway.
5. Check for sticking ball check valves. If material
being pumped is not compatible with pump,
elastomer, swelling may occur. Replace ball
check valves and seals with proper elastomers.
Also, as the check valve balls wear out, they
become smaller and can become stuck in the
seats. In this case, replace balls and seats.
6. Check for broken inner piston which will cause
the air valve spool to be unable to shift.
7. Remove plug from pilot spool exhaust.
Pump runs but little or no product flows.
1. Check for pump cavitation; slow pump speed
down to allow thick material to ow into liquid
chambers.
2. Verify that vacuum required to lift is not greater
than the vapor pressure of the material being
pumped (cavitation).
3. Check for sticking ball valves. If material
being pumped is not compatible with pump
elastomers, swelling may occur. Replace ball
check valves and seats with proper elastomers.
Also, as the check valve balls wear out, they
become smaller and can become stuck in the
seats. In this case, replace balls and seats.
Pump air valve freezes.
1. Check for excessive moisture in compressed
air. Either install a dryer or hot air generator
for compressed air. Alternatively, a coalescing
lter may be used to remove the water from the
compressed air in some applications.
Air bubbles in pump discharge.
1. Check for ruptured diaphragm.
2. Check tightness of outer pistons.
3. Check tightness of fasteners and integrity of
o-rings and seals, especially at intake manifold.
4. Ensure pipe connections are airtight
Product comes out air exhaust.
1. Check for diaphragm rupture.
2. Check tightness of outer pistons to shaft.
