Operation and Maintenance Guide ADPB 15 Plastic Pump Series
Please check that the fluid 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 figure 1 and ensure that the
piping system is independently supported
and does not load the pump. The pumps are
not designed to take the continuous and often
pulsating load of a piping system. Important
to use a flexible 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.
The Teryair diaphragm pump generates a alternate stroking of the diaphragms against the
fluid in the liquid chambers of the Pump. This reciprocatory action is responsible for the fluid
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 fluid flowing
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. This 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 fluid deliv-
ery.
