1. INSTALLATION
1.1. Operation principle
The Tapflo diaphragm pump is driven by compressed air. The two diaphragms are connected
by a diaphragm shaft and pushed back and forth by alternately pressurising the air chambers
behind the diaphragms using an automatically cycling air valve system.
The Suction Cycle:
➢
Suction
One diaphragm creates a suction action in one chamber (on the right) when being pulled
back from the housing.
➢
Discharge
The other diaphragm simultaneously transmits the air pressure to the liquid in the second
chamber (on the left) of the housing, pushing it towards the discharge port.
During each cycle the air pressure on the back of the discharging diaphragm is equal to the
head pressure on the liquid side. Tapflo diaphragm pumps can therefore be operated against
a closed discharge valve with no negative effect to the life of the diaphragms.
1.2. Receiving inspection
Although precaution is taken by us when packing and shipping, we urge you to carefully check
the shipment on receipt. Make sure that all parts and accessories listed on the packing list are
