Concept
The Diaphragm Vacuum Pumps
from KNF are based on a simple
principal - an elastic diaphragm,
fixed on its edge, moves up and
down its central point by means of
an eccentric. In this way the medium
is transferred using automatic
valves.
The pumps are equipped with the
patented stress-optimized struc -
tured diaphragm, resulting in a high
pneumatic performance, a durable
product and compact size. Special
valves ensure that the product can
cope easily with vapour and condensation.
Several different drive motors are
available. Please contact us for
more information.
ATEX versions available upon
request.
Features
Uncontaminated flow
No contamination of the media due
to oil-free operation
Maintenance-free
Compact size
due to structured diaphragm
High performance
because of structured diaphragm
High level of gas tightness
Long product life
thanks to structured diaphragm
Very quiet and little vibration
Copes well with vapour and condensation
Starts against vacuum
May be used as roughing pumps for
turbomolecular pumps
Can operate in any installed position
Areas of use
The Diaphragm Pumps offer a high
level of performance despite their
small size, as well as an excellent
price performance ratio. They are
required especially in the fields of
analysis, medicine, production
technology or be used as roughing
pump for turbomolecular pumps.
The pumps are used for sucking
gases, taking samples (even liquids
in a vacuum) and evacuating vessels
and systems.
THE DYNAMIC MASS BALANCING
For applications that demand especially
smooth running throughout the
whole working range of the pump,
KNF has developed, and applied for
patent protection on, a dynamic
mass balancing. It automatically
damps out the out-of- balance resulting
from gas forces.

HINTS ON FUNCTION, INSTALLATION AND SERVICE
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 compress
completely oil-free.
Diaphragm pump
HINTS ON INSTALLATION AND
OPERATION
Range of use: Transferring air and
gases at temperatures between +5°C
and +40°C.
Permissible ambient temperature:
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 vapors - please contact us.
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 designed to start
against vacuum. Pumps that start
against pressure are available on
request.
To prevent the maximum operating
pressure being exceeded, restriction
or regulation of the gas 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.
For pumps with dynamic mass balancing:
the pump must be supported on
rubber mounts or springs so that the
natural frequency of the system is
f ei >1.7 Hz. For lower values of f ei correct
operation of the dynamic mass
balancing cannot be guaranteed.
For pumps with dynamical mass balancing:
if the pump is mounted on a platform
that is itself a vibrating system, or
contains one, care must be taken to
ensure that the two systems do not
interfere with each other.
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
telephone number).
KNF - the competent partner for vacuum
and compressor technology. Especially
for unusual problems.
