SAFETY MANUAL

PRINCIPLE OF PUMP

OPERATION

This spring loaded check valve 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 rod, 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 230 feet
(70 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
internally mounted, pilot operated, 2 way type
distribution valve. When the spool shifts to one
end of the centre body, inlet pressure is applied
to one chamber and the other diaphragm
chamber exhausts. When the spool shifts to the

Page 1

opposite end of the centre body, the pressure
to the chambers is reversed.
The chambers are connected with rotatable
manifolds with a spring loaded suction and
discharge check valve for each chamber,
maintaining flow in one direction through the
pump.

INSTALLATION

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.

The pump is fitted with spring loaded check
valves, as a result the pump can be mounted in
any position to suit the application needs.
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.

NOTE: A Pressure Regulator should be
installed where air supply could exceed 100
psi.

SAFETY

Your B10 pump is a high performance unit
capable of achieving

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% leakproof
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).

high outputs at high

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 clean water. 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 Ensure that only the

recommended grade of lubricating oil is used.
BLAGDON PUMPS do not require any dedicated

lubrication system, however a periodical
application of an SAE 10 lubricating oil will help to
prolong seal life. Other grades of oil may cause
the Air Logic System to operate intermittently,

Page 2

thereby causing a loss of output and failure to
operate.

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

installation and start-up. It is the
