FUNCTION OF KNF DIAPHRAGM
VACUUM PUMPS AND COM-
PRESSORS
An elastic diaphragm is moved up and
down by an eccentric (see illustration).
On the down-stroke it draws the air or
gas being handled through the inlet valve.
On the up-stroke the diaphragm forces
the medium through the exhaust valve
and out of the head. The compression
chamber is hermetically separated from
the drive mechanism by the diaphragm.
The pumps transfer, evacuate and com-
press compley oil-free.

HINTS ON INSTALLATION AND
OPERATION
• Range of use: Transferring air and gases
at temperatures between +5°C and
+40°C
• Please check the compatibility of the
materials of the pump head, diaphragm
and valves with the medium.
• The KNF product line contains pumps
suitable for pumping aggressive gases
and vapours - please contact us.
• Permissible ambient temperature:
between +5°C and +40°C
• The standard pumps are not suitable
for use in areas where there is a risk
of explosion. In these cases there are
other products in the KNF program -
please ask us for details
• The pumps are not designed to start
against pressure or vacuum; when a
pump is switched on the pressure in
the suction and pressure lines must be
atmospheric. Pumps that start against
pressure or vacuum are available on
request
• To prevent the maximum operating
pressure being exceeded, restriction or
regulation of the air flow should only
be carried out in the suction line
• Components connected to the pump
must be designed to withstand the
pneumatic performance of the pump
• Install the pump so that the fan can
draw in sufficient cooling air
• Fit the pump at the highest point in the
system, so that condensate cannot
collect in the head of the pump - that
prolongs working-life.
HINTS ON SERVICE
The diaphragm and valve plates are the
only parts of the KNF diaphragm pumps
subject to wear. They are easy to change,
as no special tools are needed.
If you have any questions, please call our
application engineers (see below for
contact ephone number).
