Caution - Operating temperature limitations are as follows:
Materials
Buna-n - General purpose, oil resistant. Shows good solvent, oil, water and hydraulic fluid resistance. Should not
be used with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
EPDM - Shows very good water and chemical resistance. Has poor resistance to oils and solvents, but is fair on
ketones and alcohols.
Neoprene - All purpose. Resistant to vegetable oil. Generally not affected by moderate chemicals, fats greases
and many oils and solvents. Generally attacked by strong oxidising acids, ketones, esters, nitro hydro carbons and
chlorinated aromatic hydrocarbons.
Santoprene® - Injection moulded thermoplastic elastomer with no fabric layer. Long mechanical flex life.
Excellent abrasion resistance.
Virgin PTFE - Chemically inert, virtually impervious. Very few chemicals are known to react chemically with
PTFE : molten alkali metals, turbulent liquid or gaseous fluorine and a few fluoro-chemicals such as chlorine
trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures.
Viton® - Shows good resistance to a wide range of oils and solvents : especially all alphatic, aromatic and
halogenated hydrocarbons, acids, animal and vegetable oils.
Polypropylene - High strength, light weight, corrosion resistant polyolefin which easily withstands most chemi-
cals, with no known solvent at room temperature.

OPERATION
This ball valve type diaphragm pump is
powered by compressed air and is a 1:1 ratio
design. The inner side of one diaphragm
chamber is alternately pressurised while
simultaneously exhausting the other inner
chamber. This causes the diaphragms, which are
connected by a common shaft secured by plates
to the centres of the diaphragms, to move in a
reciprocating action. (As one diaphragm
performs a discharge stroke the other diaphragm
is pulled to perform the suction stroke in the
opposite chamber.) Air pressure is applied over
the entire inner surface of the diaphragm while
liquid is discharged from the opposite side of
the diaphragm. The diaphragm operates in a
balanced condition during the discharge stroke
which allows the pump to be operated at
discharge heads of over 200 feet (61 meters) of
water.
For maximum diaphragm life, keep the pump as
close to the liquid being pumped as possible.
Positive suction head in excess of 10 feet of
liquid (3.048 meters) may require a back
pressure regulating device to maximize
diaphragm life.
Alternate pressurising and exhausting of the
diaphragm chamber is performed by an
externally mounted, pilot operated, 2 way type
distribution valve. When the spool shifts to one
end of the valve block body, inlet pressure is
applied to one chamber and the other diaphragm
chamber exhausts. When the spool shifts to the
opposite end of the valve body, the pressure to
the chambers is reversed. This alternating

Installation Guide
Fig. 1
movement of the spool inside the valve body is
controlled by a pilot air pressure signal held
against the diaphragm shaft, between seals in the
diaphragm shaft bushes. This signal is released,
triggering the movement of the spool, when pilot
holes in the diaphragm shaft align with the held
pilot signal, sending the signal to exhaust, which
in-turn causes a pressure imbalance around the
spool, sending it to the opposite end of the valve
body. This simultaneously sends inlet pressure
to the opposite chamber.
The chambers are connected by manifolds with a
suction and discharge ball valve for each
chamber, maintaining flow in one direction
through the pump.
INSTALLATION
The typical installation shown in FIG. 1 is only a
guide to selecting and installing system
components. Your installation will depend on
the type of fluid being pumped and your
application needs. To reduce the risk of serious
bodily injury and damage to property, never use
fluids in this pump which are not compatible
with the wetted components. Contact your local
distributor or the manufacturer for system design
assistance & compatibility if necessary.
Mount the pump in an upright position. Failure
to ensure an upright position may result in loss
of or poor priming characteristics. Ensure the
pump is securely mounted to avoid movement
and possible risk of bodily injury.
PRESSURE The pump delivers the same
pressure at the discharge outlet as the air
pressure applied at the air inlet (unless pump is
CAUTION !
The air exhaust should be piped
to an area for safe disposition of
the product being pumped, in the
event of diaphragm failure.
configured as a 2:1 ratio model).
NOTE: Pressure Regulator (H) should be
installed where air supply could exceed 125
psi.
SAFETY
Your BLAGDON PUMP is a high
performance unit capable of achieving
high outputs at high efficiencies. However, as
is common with pneumatic equipment, the
pump efficiencies is reliant upon the air being
clean, dry and filtered. Failure to comply with
these requirements may lead to loss of
performance and reduced component life and in
extreme cases, permanent damage to the pump.
To avoid leaks, ensure that all fluid connections
are tight. The use of PTFE thread tape correctly
applied should be used to ensure 100% leak
proof connections. Failure to ensure 100%
sealability of the suction connection could
adversely affect suction performance.
If you are pumping hazardous fluids, or
operating the pump in an enclosed area, it is
essential that the exhaust from the pump is
piped away to a safe location. When pumping
hazardous fluids the above instructions must be
adhered to in order to ensure safe operating
procedures. (Under certain operating
conditions the failure of internal components
can lead to the pumped fluid being exhausted
via the pump exhaust outlet).
WARNING
NEVER place your hands over or near the
pump suction inlet. Powerful suction could
cause serious bodily injury.
FLUSH THE PUMP This pump was tested
with water containing an oil-based rust
inhibitor. If this solution could contaminate or
react with the fluid you are pumping, flush the
pump thoroughly with a solvent/detergent to
clean internal components. The solvent/
detergent must be compatible with the pump
materials of construction. Care should be taken
to flush the pump each time it is disassembled
for maintenance or repair.
CAUTION
All BLAGDON PUMPS are built lubricated
with grease during assembly and need no
further lubrication. If the use of oil cannot be
avoided, this will not present any problems. A
light No. 2 class lithium grease is
recommended. Other grades may cause the Air
Logic System to operate intermittently, thereby
causing a loss of output and failure to operate.
Other seals are available for “clean room”
conditions
If the pump accelerates or is running too fast
due to a lack of fluid, then stop it immediately
by shutting off the air supply. A dry pump will
accelerate to a high speed causing wear to
elastomers.
If the fluid you are pumping tends to dry up or
set when it is not moving, then flush the pump
as often as necessary to prevent the fluid from
drying in the pump. Drain the pump thoroughly
before storing.
If feasible, invert pump to allow any fluid to
drain from the non-return valves.

Important Warnings and Safety Information
IMPORTANT
Read these safety warnings and instructions in this manual completely, before installation and start-up of the pump. It
is the responsibility of the purchaser to retain this manual for reference. This manual must be kept with, and supplied
with the pump at all times. Failure to comply with the recommendations stated in this manual will damage the pump,
and void factory warranty. These instructions are available if required, in the language or languages of the country or
countries in which the equipment is used. Please refer to the manufacturer for details.
IMPORTANT!
This pump is pressurized internally with air pressure during operation. Always make certain that all bolting is in good condition and that
all of the correct bolting is reinstalled during assembly. End-user must ensure correct fitting of Inlet / Outlet connections. Crossed
threads or over tightening of connections will result in leaks. Quick action/release connections are not recommended. If thei r use is
unavoidable, the levers must be locked to avoid them being forced apart in a hazardous manner.
WARNING!
Before maintenance or repair, shut off the compressed air line, bleed the pressure, and disconnect the air line from the pump. The discharge line may be pressurized and must be bled of its pressure. End-user must ensure correct regulation of air supply pressure, as any
increase in air pressure results in a similar increase in product pressure if stalled-out.
WARNING!
Before doing any maintenance on the pump, be certain all pressure is completely vented from the pump, suction, discharge, piping, and
all other openings and connections. Be certain the air supply is locked out or made non-operational, so that it cannot be started while
work is being done on the pump. Be certain that approved eye protection and protective clothing are worn at all times in the vicinity of
the pump. Failure to follow these recommendations may result in serious injury or death.
WARNING!
Airborne particles and loud noise hazards. Wear ear and eye protection.
WARNING!
Take action to prevent static sparking. Fire or explosion can result, especially when handling flammable liquids. The pump, piping,
valves, containers or other miscellaneous equipment must be grounded. Refer to exhaust safety instructions on page 9.
WARNING!
When used for toxic or aggressive fluids, the pump should always be flushed clean prior to disassembly. User must ensure chemical
compatibility, and any pressure / temperature limits are not exceeded. These instructions include all the information for relevant
diaphragm temperature limits. Pump temperature range can also be found on data-plate attached to the pump.
If pump is not used for more than 5 days, care must be taken when restarting. If in any doubt, remove pump from line and flush with a
suitable cleaner. Solidified deposits within the pump may cause damage to the diaphragms.
HG-CF-910 – REV Q 06.04.11
CAUTION!
Before pump operation, inspect all gasketed fasteners for looseness caused by gasket creep. Re-torque loose fasteners to prevent
leakage. Follow recommended torques stated in this manual. In cases of excess vibration, Blagdon recommend fitting a Pulsation
Dampener to remove effects of pulse actions from pump operation. Flexible connections can be used, but must be kept to a minimum
length necessary to avoid sharp flexing or straining movements.

SERVICE
The following sections give a general
overview on how to service all
models of BLAGDON Diaphragm
Pumps. For details on individual part
numbers, quantities, materials, etc.,
please consult the parts list supplied
with the pump.
NOTE : Before commencing
any service or maintenance work
on the pump, ensure that the air
supply has been disconnected or
isolated.
AIR VALVE SYSTEMS
PNEUMATIC TYPE Remove the 4
screws securing the valve block to
the valve chest, together with any
associated gaskets or seals.
Remove slide valve plate & slide
valve from the valve block assembly.
Clean all parts thoroughly and
inspect for excessive wear, replacing
where necessary.
The slide valve and valve plate
contact faces should be flat and free
from scratches. A light polishing on a
flat surface with a fine abrasive paper
will remove most scratches.
If excessive wear is suspected in the
valve block bore or valve carrier,
remove the valve block plugs and
withdraw the valve carrier. Check
valve block plug o-rings for wear or
attack & replace where required.
Clean the valve carrier & valve block
bore with white spirits to remove any
oil films.
NOTE : T h e n o m i n a l
diametrical clearance between the
valve carrier and the valve block
bore should be 0.05 - 0.09mm. A
clearance in excess of this will
cause the valve system to run
erratically.
Apply a light grease to the valve
bl oc k p lu g O -rings whe n reassembling into the valve block bore.
Any damage to the O-ring may cause
the valve system to malfunction.
Re-a sse mbl e the val ve blo ck
assembly & re-torque in accordance
to the settings shown in the parts list.
In the event of a complete air-side
overhaul, the pump should be disassembled down to the centre
section assembly as described later
in the “Wet-Side Overhaul” section.
With the valve block assembly
dismantled, remove the inner covers
where appropriate.
A careful note of the position of all
related seals and gaskets should be
made to facilitate re-assembly.
Remove diaphragm shaft bushes,
where appropriate, and check all
seals and „O‟ rings for wear or
d a m a g e. I f wo r n , r ep l ac e
immediately.
NOTE:- The integrity of the
diaphragm shaft seals is essential
for the correct functioning of all
pneumatically actuated valve
systems.
Check the diaphragm shaft for
excessive wear as this will result in
premature seal failure. Replace as
required. Lubricate all components
and re-assemble as detailed above,
in reverse order. Ensure the correct
position of all components detailed in
all sectional assembly drawings.
WET-SIDE OVERHAUL
REP L A CING BAL L VA L VES
Remove discharge manifold from
pump asse mb ly to gether with
associated valve balls, seats and „O‟
rings.
NOTE :- The orientation of the
valve seat relative to the valve ball
should be noted as incorrect
positioning may result in a
performance loss.
Turn pump through 180o and remove
the suction manifold. Clean and
inspect the components. Check for
any wear or damage and replace as
required.
NOTE :- Ball or valve seat wear
may result in loss of performance
and suction lift.
Re-assemble the valve balls/seats
and ensure manifolds are adequately
torqued to the settings shown in the
parts list.
R E P LAC I NG D I A P H R A GM S
Remove both suction and discharge
manifolds as detailed in the previous
section, removing all ball valves,
seats and „O‟ rings.
Loosen and remove both outer
covers from the pump assembly.
The orientation of the covers should
be noted so as to facilitate reassembly.
Holding one of the frontplates in a
vice, („soft jaws‟ should be fitted), or
with an adjustable spanner, loosen
and remove the frontplate from the
opp osi te e nd. Remove th e
diaphragm, backplate and bumpstop
from diaphragm shaft.
Carefully withdraw the diaphragm
shaft from the centre section and
hold the free end in a vice, holding
between the flats machined on the
end. Loosen and remove the
frontplate and remove the diaphragm
tog e t her wi th back plate a n d
bumpstop (where fitted).
NOTE :- Care should be taken with
all plastic, coated and hygienic
pumps, so that the surface of the
frontplate is not damaged.
Thoroughly clean all parts and check
for wear, damage, swelling, cracking,
delamination and chemical attack.
Replace components where required.
NOTE :- Rubber diaphragms
should be replaced if they are
worn to such an extent that the
fabric re-enforcing is evident on
the surface of the diaphragm.
Fo r pu mps fi tte d w ith PT FE
diaphragms, a light coating of grease
should be applied to the back-up
diaphragm prior to re-assembly.
Before re-assembly, it is advisable to
check the condition of the diaphragm
shaft seal/‟O‟ rings for wear or attack.
If either is evident, it is recommended
that they be replaced.
Assemble the diaphragms onto the
shaft in a reverse sequence to their
removal. Care should be taken as to
the orientation of the diaphragm
relative to the front and back plates.
All diaphragms have “AIR SIDE”
moul de d onto one s ide. The

EXHAUST SAFETY WHEN PUMPING HAZARDOUS LIQUIDS
WARNING!
In the event of diaphragm rupture, pumped material may enter the air end of the pump, and be discharged into the atmosphere. If pumping
a product which is hazardous or toxic, the air exhaust must be piped to an appropriate area for safe disposition.
Flooded Suction Installation
Submerged Installation
Suction Lift Installation
Exhaust Safety :-
When a diaphragm fails during operation, pumped liquid can enter and contaminate the air side of the pump. If diaphragm failure is not
severe, i.e. a small split or hole, then the pump can continue to run, with air being forced into the product being pumped. If however the
failure is more serious, then the pump may stop, with fluid or fumes being expelled through the exhaust. Under these conditio ns it is
recommended that the exhaust is piped away to a safe area. In standard suction lift conditions this can simply be done by piping from the
exhaust connection to a safe area. Multiple installations can be piped to a common connection, then to a safe area. In flooded suction
conditions the exhaust must be taken to a point higher than the fluid level to prevent any siphoning away. In submerged conditions ensure
exhaust is piped away above fluid level.
In all conditions ensure exhaust outlet is not expelling across a non-conductive surface. The exhaust must not be placed less than 100mm
from any non-conductive surface, as this may generate a propagating brush discharge resulting in a possible ignition source.
HIGH TEMPERATURE INSTALLATIONS
In situations where the temperature of the fluid to be pumped is likely to exceed 100°C, a high temperature pump
code must be specified. This is signified using an „X‟ in the last part of the pump code as shown.
“XTS” in place of “TTS”.
This indicates the following specification amendments :Diaphragm Shaft Seals will be changed from Polyurethane to Viton. Back-up diaphragms and any bumpstops will
be changed to Viton. In extreme cases only, any gaskets could be changed to a higher temperature spec., and the
diaphragm shaft bushes could be changed from plastic to metal.
