Operating and Safety Instruc-
tions
Warning. Static Electricity
Static sparks can cause explosion resulting
in severe injury or death.
Ground the pump and the pump connec-
tions like hoses and containers into which
or from the uid is being transferred.
Connect the grounding wire to any bolt on
the pump.
Check continuity of electrical path to
ground at regular intervals.
Consult local building and electrical codes
for grounding requirements where needed.
Use hoses containing a grounding wire.
Warning: Pump Exhaust
In case of a diaphragm failure, uid being
pumped may spray out from the exhaust
of the pump. is may cause severe injury
depending on the uid being pumped.
If the uid is hazardous, pipe away the
exhaust to a safe remote location using a
generous diameter ¾” pipe preferably with
a grounding arrangement, and ret the
muer at the end of this arrangement.
Always wear safety glasses while in the
vicinity of an operating pump.
Warning: Overpressure/Haz
ardous Pressure
Do not exceed the max supply air pressure
of 125 PSI.
Make sure all connected hoses and pipe-
lines are rated to operate safely with the
pressures generated by pump of 125 PSI.
Do not open or handle pump or hoses
while pressurized.
Disconnect air supply line and relieve pres-
sure from the system by carefully opening
discharge and supply lines.
Warning: Hazardous Materials
Do not move a pump that contains hazard-
ous uids trapped inside it. Please observe
prescribed handling and safety codes.
Drain the pump safely, by turning it upside
down and collecting the uid safely, before
moving the pump.
Warning :Explosion
Please check compatibility of uids in-
tended to be handled with the materials of
construction of the pump. Severe reactions
and explosions may occur if materials are
incompatible. Caution: Chemical

e Teryair Stroke diaphragm pump generates a alternate stroking of the diaphragms against
the uid in the liquid chambers of the Pump. is reciprocatory action is responsible for the
uid being pumped.
It is possible to control the output of the pump by controlling the supply air pressure.
It is also possible to control the output of the pump by throttling action on the uid owing
in the outlet piping by means of a valve. if such a valve is shut completely the pressure in the
discharge piping increases to a point when the pressure at pump discharge equals it and the
pump comes to a stop. is causes no damage to the pump and the pump consumes no more
energy.
Upon opening of the valve, the pump starts reciprocating once again and resumes uid deliv-
ery.
Operating Instructions
Please check that the uid being pumped
is compatible with the wetted parts of the
pump. Refer Cole Parmer compatibility
(http://www.coleparmer.in/Chemical-Re-
sistance) guide for details. Note that
chemical compatibility may change with
temperature; take this into account while
selecting pump material.
Caution: Structural support
Please refer gure 1 and ensure that the
piping system is independently supported
and does not load the pump. e pumps
are not designed to take the continuous
and oen pulsating load of a piping system.
Important to use a exible connection be-
tween rigid piping and pump casings.
Caution: Running dry,
disconnection of hoses
when not in use
Although these pumps can be run dry for
long periods, it is advisable to avoid this
as it causes unnecessary wear of wearing
parts.
Caution: Operator
understanding
Please ensure that all operators have read
this manual and have the required un-
derstanding of safe working practices and
are equipped with safety equipment when
working on/around the pump.
Caution: Using genuine
teryair fittings & spares
Use genuine teryair parts to ensure correct
pump operation and maximize life.
Warning
Conditions for Certification
1. Control of Environmental humidity to
minimize the generation of the static
electricity.
2. Protection from direct airow causing a
charge transfer.
3. Touch with an insulating object to avoid
electrostatic charge hazard.
4. Clean the surface with damp cloth only to
avoid electrostatic charge hazard.
