Operating and Safety Instruc-
tions
Warning: Static Electricity
Static sparks can cause explosion result-
ing in severe injury or death.
Ground the pump and the pump connections
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 be-
ing 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 ex-
haust to a safe remote location using a gener-
ous diameter pipe preferably with a ground-
ing arrangement, and ret the muer at the
end of this arrangement.
Always wear safety glasses while in the vicini-
ty 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 pipelines
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 haz-
ardous 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
intended 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-326-REV -01

Operation and Maintenance Guide SDP 25 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-Resistance) 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 between 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 understanding
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

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 por-
tion of the seal to form kidney bean shape.
(Refer Fig. A)
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 possi-
ble, this will allow the seal to travel down the
bushing bore easier. (Refer Fig. B)
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 pli-
ers. 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 re-sized, 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 completely eliminat-
ed.
j. Lubricate the edge of the sha with specied
lubricant.
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.

with its O-ring (30) out of the air valve body
(25).
(Note - Ensure that the metal cover is always
installed with an end cap 29)
c. Use the same bolt to pull the air piston
assembly (36) with all its seals. is piston
assembly (36) needs to replace as a single
piece.
d. In order to remove the end plug assembly
(37) with its seals, remove the screw (32)
using allen key and push it to remove. End
plug assembly (37) also needs to be replace
with seals.
e. Now remove O- ring (35) from End cap (37)

Re-Assembly
Upon performing applicable maintenance to
the air distribution system, the pump can now
be reassembled. Please refer to the dis-assembly
instructions for photos and parts placement. To
reassemble the pump, follow the dis-assembly
instructions in reverse order. e air distribution
system needs to be assembled rst, then the Dia-
phragms and nally the wetted path. Please nd
the applicable torque specications on this page.
e following tips will assist in the assembly
process.
a. Clean the inside of the center section sha
bore to ensure no damage is done to new
seals.
b. Stainless bolts should be lubed to reduce the
possibility of seizing during tightening.
c. Level the water chamber side of the intake/
discharge manifold to ensure a proper sealing
surface. is is most easily accomplished by
placing them on a at surface prior to tight-
ening their clamp bands to the desired torque
(see below for Torque Specications).
d. Be sure to tighten outer pistons simultane-
ously on PTFE-tted pumps to ensure proper
torque values.
e. Ensure proper mating of liquid chambers to
manifolds prior to tightening vertical bolts.
Overhang should be equal on both sides.
f. Apply a small amount of Loctite 242 to the
sha interval threads before the diaphragm
assembly.
