DESCRIPTION
Air operated double diaphragm pumps are air-powered, reciprocating
positive displacement pumps.
INSTALLATION
RECOMMENDATIONS
• Install the pump as close as possible to the fluid being pumped to
minimise the suction head.
• For the ease of operation and service, install the pump so there is
enough space around it.
• If the pump is installed in a place where fluid leakage can cause an
environmental impact, the exhaust should be directed to a place
where it can be contained.
UP pumps can be installed with flooded suction, suction lift or submerged
in the fluid pumped. The figure below shows the recommended
configuration for the pump installation.

WARNING
• Remove the pump air muffler.
• Connect a hose with a 1/2" NPT thread to the new exhaust port and
install the muffler at the end of the hose.
• Be sure the air exhaust is directed to a safe place.
AIR CONNECTION
WARNING
• To ensure that the air flow is sufficient to meet the pump
demand, the air pipe diameter must be equal to the pump air
inlet.

They have two opposite pump volumes and a diaphragm divides each
volume into an air and a liquid chamber. The diahphragms are connected
with a shaft. During one pumping stroke, the fluid is suctioned into one
of the liquid chambers while simultaneously the other one is discharged.
• When installing the pump in its place, use brackets to secure its base.
• Fasten all bolts with the torques contained in this manual (REPAIR AND
MAINTENANCE section). Let the pump running for a whole day. After
that, check the torques again.

SUCTION
• Air treatment equipment must be dimensioned to meet pump air
demand. It must be installed as close as possible to the pump unit.
• Using air quick couplers to connect the air hoses facilitates
pump maintenance.
