Functional description
sera air driven diaphragm pumps are displacement pumps
which can run dry with no harm to the pump.
They are driven by dry, non-lubricated compressed air.
The control valve ensures that the air chambers behind the
diaphragms are alternatingly supplied with compressed air.
One diaphragm is pushed to the front
= Pressure stroke (A)
and the other to the rear
= Suction stroke (B).
The special construction of the control valve ensures that the
pumps are always driven and cannot come to an undesired
stop.
The valve balls open and close in stroke rhythm with the
diaphragms.

7.1
When setting the air driven diaphragm pumps in place, be sure
that the suction and pressure connections are oriented
properly.
CAUTION !

When installing the air
driven diaphragm pump,
provide for sufficient
space for later
maintenance work.
7.2
Air driven diaphragm pumps made of conductive material,
which should be used for feeding flammable media, must be
sufficiently grounded to prevent the risk of explosion or fire.
CAUTION !
The air driven diaphragm pump must always be grounded
separately from other devices. No ground or improper
grounding renders the required safety regulations with
respect to explosion hazard ineffective.
A high-capacity ground
with appropriate cable
cross-section must be
used!
Subject to technical modifications!
