1. Review the NOMAD Chemical Field Guide
for all applications. The information
provided is the “best thinking available”
regarding chemical compatibility. The
guide however, does not provide a
recommendation.
2. Always wear safety glasses during pump
operation. A diaphragm rupture may force
liquid to exit via air exhaust.
3. Whenhandlingammableuids,prevent
static sparking by properly grounding
the pump.
4. Do not exceed 125 psig (8.6 bar).
5. Prior to maintenance, compressed air
line should be disconnected to allow air
pressure to bleed from pump.
6. Tighten all clamp bands and hardware
parts prior to installation. Fittings may
loosen during transportation.

PUMP DESIGNATION SYSTEM

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. NOMAD
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.

2 bar (30 psig) head pressure.
Example: To pump 530 lpm (140 gpm) against
a discharge pressure head of 2.1 bar (30 psig)
requires 4.1 bar (60 psig) and 136 Nm3/h (80
scfm) air consumption. (See dot on chart.)
Caution: Do not exceed 8.6 bar (125 psig) air
supply pressure.
Flow rates indicated on chart were determined by pumping water.
For optimum life and performance, pumps should be specified so that daily operation
parameters
will fall in the center of the pump performance curve.

SUGGESTED INSTALLATION
NTG80 NOMAD TRANS-FLO™
The suction pipe size should be at least 76mm (3")
diameter or larger if highly viscous material is being
pumped. The suction hose must be non-collapsible,
reinforced type as the NTG80 is capable of pulling
a high vacuum. Discharge piping should be at least
76 mm (3"); larger diameter can be used to reduce
friction losses. It is critical that all ttings and con-
nections are airtight or a reduction or loss of pump
suction capability will result.
Every pump location should have an air line large
enough to supply the volume of air necessary to
achieve the desired pumping rate.
Unnecessary elbows, bends and ttings should be
avoided. Pipe sizes should be selected so as to keep
friction losses within practical limits. All piping should
be supported independently of the pump.
Expansion joints can be installed to aid in absorbing
the forces created by the natural reciprocating action
of the pump. Flexible connections between the pump
and rigid piping will also assist in minimizing pump
vibration. A surge suppressor should be installed to
protect the pump, piping and gauges from surges and
water hammer.
When pumps are installed in applications involving
ooded suction or suction head pressures, a gate
valve should be installed in the suction line to permit
closing of the line for pump service.
The NTG80 can be used in submersible applica-
tions only when both wetted and no-wetted portions
are compatible with the material being pumped. If
the pump is to be used in a submersible application,
a hose should be attached to the pump’s air exhaust
and the exhaust air piped above the liquid level.

Note: In the event of a power
failure, the shutoff valve should
be closed, if the restarting of
the pump is not desirable once
power is regained.
TROUBLESHOOTING
NTG80 NOMAD TRANS-FLO™
Pump will not run or runs slowly.
1.Checkairinletscreenandairlterfordebris.
2.Checkforstickingairvalve,ushairvalve
in solvent.
3. Check for worn out air valve. If piston face in air
valve is shiny instead of dull, air valve is worn
beyond working tolerances and must
be replaced.
4. Check center block rings. If worn excessively, they
willnotsealandairwillsimplyowthroughpump
and out air exhaust.
5. Check type of lubricant being used.
ISO 15-5 wt. recommended.
Pump runs but little or no product ows.
1. Check for pump cavitation; slow pump speed down
to match thickness of material being pumped.
2. Check for sticking ball valves. If material being
pumped is not compatible with pump elastomers,
swelling may occur.
3. Make sure all suction connections are
air tight.
Pump air valve freezes.
Check for excessive moisture in compressed air.
Air bubbles in pump discharge.
1. Check for ruptured diaphragm.
2. Check for tightness for clamp bands,
especially at intake manifold.
Product comes out air exhaust.
1. Check for diaphragm rupture.
2. Check tightness of piston plates to shaft.
Pump rattles.
Create false discharge head or suction lift.
