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 pipe preferably with a
grounding arrangement, and ret the muf-
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
compatibility

FF-MM-344-REV - 05

Operation and Maintenance Guide DP 75 Metal Series
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.

Location selection
Pump location must be easily accessible with reasonable
space around for maintenance operations.
Pump dimensional data for each variant is available in
section showing exploded views
Air supply
Compressed air at 90 PSI ( Stroke pumps can take a max
of 125PSI), free from moisture and having an oil mist is
essential. Use of a lter (50 microns), a lubricator and a
regulator is highly recommended and should be installed
as close as possible to the pump inlet.
Ensure correct grade of oil is used in thelubricator bowl.
Too thick oil may slow down the valve shiing mecha-
nism and aect pump performance. See suggested
lubricants on page no 5.
Piping
see section on safety if used in hazardous area)
See Figure 1.
Suction side 3 inch or larger, non-collapsible
Delivery side 3 inch or larger.
A minimum number of bends and ttings to be used.
A exible connection between suction, delivery and air
supply piping is highly recommended such that piping
stresses and loads do not transfer to pump housing.
Select piping materials such that chemical compatibility is
maintained with the uid being pumped.
Suction
Ensure that the suction head aer installation is well with-
in the pumps suction capabilities
Muffler
Use of supplied muer is recommended to bring pump
operation sounds down to comfortable levels, in case of
hazardous uids handling, please read section of safety
regarding piping away of exhaust see

Maintenance
Regular inspection and maintenance schedules will greatly enhance the life of the pump and
will ensure a trouble free and safe working environment with little chance of breakdowns.
Follow the instructions in “Disassembly and Reassembly” of the pump and in the
troubleshooting section.
Use genuine Teryair spares and if possible mention the serial number of the pump when
ordering spares.
Always replace elastomers as a set, eg diaphragms, balls and seats.
1) Replacement of Diaphragm
a. Unscrew both bolt (25) & nut (26) as shown
in the exploded view and proceed to remove the small
clamp (29). Repeat for the other three small clamps.
Remove the outlet (3) & inlet (2) respectively. Examine
the balls, seals (and seats) for wear.
b. Now unscrew hex socket head bolt (28) &
nut (24) of any one side and proceed to remove the big
clamp (21). Now remove the outer chamber (6). Now
repeat the same procedure to remove the second outer
chamber (6).
c. Now with the help of two spanner hold one of
the across at of one outer ange (5) and rotate the sec-
ond outer ange (5) to disassemble it from the air disc
(1A).Now pull out the sha assembly out of the center
piece (1).Remove the diaphragm (11),& inner ange (4)
by unscrew the hex bolt (22).
*For ALT/SST series pullup backup diaphragm (11),
&PTFE diaphragm (11A), Inner spacer (9) & inner
ange (4). Now pull the sha assembly from the centre
piece (1).
d. Now hold the sha (7) in a vice with proper
packing. Care must be taken not to damage the sha
outer surface. Now remove the outer ange (5) with
spanner. en remove the same parts which mention in
column C.
*For ALT/SST series use same process which mention
in column C.
e. Now replace the diaphragms (11). Ensure that
Diassembly and Re-assembly

Operation and Maintenance Guide DP 75 Metal Series
diaphragm orientation is correct, i.e. For ALB/ ALN/ALV
the sticker side of the diaphragm (11) to be located in the
outer chamber (6). Now assemble the outer ange (5) in re-
verse manner and remove the half sha assembly from vice.
* Refer g. A for ALT & SST model the convex side of outer
ring PTFE diaphragm (11A) to be located in outer chamber
(6). For the backup diaphragm (11) the larger side of outer
ring to be located in air disc (1A) & small in the concave
groove of PTFE diaphragm (11A).
* For ALS/ ALH model AIR SIDE marking to be located
toward the air disc (1A)
f. Lubricate the edge of the sha with specied
lubricant. Slowly insert the sha with rotating motion. Care
should be taken not to damage the rod seal (8).
g. Once the half sha open portion comes out of the
bush, follow the procedure in reverse manner as described in
part (a) & (b) and assemble the pump.
2) Replacement of Shaft O rings
a. For removing the rubber rings from bush, rst
follow the step a, b & c from the diaphragm replacement.
b. Now remove the seals with the help of needle Nose
pliers. Care should be taken not to damage the inner face of
bush.
c. Once all the old seals are have been removed, the
inside of the bushing should be cleaned to ensure no debris
is le that may damage to new seals (Pressurized air is pref-
erable).
d. ese following tools can be used to aid in the
installation of new seals:
• Needle Nose pliers
• Phillips Screwdriver
• Electrical Tape
e. Wrap electrical tape around each leg of the needle
nose pliers (heat shrink may also be used) . is is done to
prevent damaging the inside portion of the new seals.
f. With a new seal in hand, place the two legs of the
nose pliers inside the seal ring. Open the pliers as wide as
the seal diameter will allow, then two ngers pull down on
the top portion of the seal to form kidney bean shape.
g. Lightly clamp the pliers together to hold the seal
into the kidney shape. Be sure to pull the seal into as tight of
a kidney shape as possible, this will allow the seal to travel
down the bushing bore easier.
h. With the seal clamped in the pliers, insert the seal
into the bushing bore and position the bottom of the seal
into the correct groove. Once the bottom of the seal is seated
in the groove, release the clamp pressure on the pliers. is
will allow the seal to partially snap back to its original shape.
i. Aer the pliers are removed, you will notice a slight
bump in the seal shape. Before the seal can be properly
resized, the bump in the seal should be removed as much
as possible. is can be done with either the Phillips screw
driver or your nger, apply light pressure to the peak of the
bump. is pressure will cause the bump to be almost com-
pletely eliminated.
j. Lubricate the edge of the sha with specied lubri-
cant.
k. Slowly insert the sha with rotating motion. is
will complete the re sizing of the seals.
l. Perform these steps for the remaining seals.
3) Replacement of Ball seat & Ball
a) Follow the step (a) of diaphragm replacement.
Replace the ball (12) & seat (13) with new one.
* For ALT, SST series change the valve seat
(13) & oring (13A) with new one.
4) Replacement of air valve and oring
of end cap
a) Unscrew socket head bolt (27) from the centre
piece (1)& remove the air valve assembly. Now remove the
circlips (20) from both ends. Now with the help of bolt (31)
pull the end cap (17) & (19) from both ends. Now slide out
the air valve (16). Change the oring (18) of both end caps.
b) While assembly rst put the end cap with pin (19)
in air valve body (14). Make sure the notch of end cap (19)
matches with the drill hole of body. Push the end cap with
oring (18) gently. Now t the circlip (20). Now slide the air
valve from other side ensuring the drill portion located in
the pin of end cap (18). Now push the end cap (17) with
oring (18) from the other end and t the circlip.
c) You can also change the gasket for air valve body
(14) & Gasket (15). Now assemble the air valve assembly in
reverse manner.
