OWNERS OPERATING &
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
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.
