pressure. This also applies when
the pump restarts after the power
has been cut off for a short period.
The components to be connected
to the pump must be designed to
withstand the pneumatic data of
the pumps (see Section 8).
The maximum permissible opera-
ting pressure (1 bar g) must not be
exceeded.
To prevent the maximum permis-
sible operating pressure being
exceeded, restriction or control of
the air or gas flow should only be
carried out in the suction line.
If restriction or control of the air or
gas flow is made on the pressure
side ensure that the maximum per-
missible operating pressure is not
exceeded.
When the pump is at a standstill
the inlet and the outlet must be at
normal atmospheric pressure.
Ensure the pump outlet is not clo-
sed or restricted.
Diaphragm and valve plates are the
only parts subject to wear. Wear is
usually indicated by a drastic
reduction in the pneumatic perfor-
mance. When replacing parts pro-
ceed as described in section 5.
Ambient conditions: see chapter
1.3.
4.2 Operation
Taking the pump into operation
Plug the mains plug of the pump
into a properly installed safety
socket.
Switch the pump on at the pump
mains switch (see fig. 1).
If cyclic drying of the pump heads
is required in the current evacu-
ation process, switch the drying
system on at the mains switch of
the control system (not included in
scope of delivery).
The drying system should only
be switched on if a container
has been attached to the pres-
sure line of the pump which will
catch the condensate; other-
wise the condensate will flow
out uncontrolled.
Check:
Tubing for correct tubing.
Electrical connections for correct
connection.
After the evacuation/process has been
completed, take the pump out of ope-
ration:
Purge the pump including the
connecting hoses with air at full
flow rate for about 5 minutes.
If the drying system is switched
on:
Switch the drying system off at the
mains switch of control system
(not included in scope of delivery).
Switch the pump off at the mains
switch of the pump.
Pull the mains plug of the pump out
of the socket.
5. Servicing:
Changing Diaphragms and Valve
Plates/Sealings
The diaphragms in both pump heads
should be changed at the same time.
When diaphragms are changed, valve
plates/sealings should also be repla-
ced. If the diaphragms are not changed
in both heads at the same time or dia-
phragms and valve plates/sealings are
not changed at the same time the
nominal performance of the pump is
not guaranteed after the service.
If a pump has been used for
aggressive or toxic substances or
other types of substances which
are hazardous, hazardous to health,
or injurious, the following points
must be observed:
1.) Clean the pump and its compo-
nents before servicing.
2.) Ensure that the service personnel
is not subject to a health hazard.
Apply the safety and protection
measures that are necessary for
the medium that has been handled
by the pump (example: the use of
protective gloves).
3.) Ensure that discarded parts and
materials are safely and correctly
