pumps are designed to prevent internal or external
explosions by enclosing parts that could ignite
either the transfer media or the surrounding
atmosphere. KNF supplies a range of explosion-proof
pumps for use in potentially explosive atmospheres.
All our pumps are ATEX-compliant and certified
in accordance with the 94/9/EC directive on
equipment and protective systems.
emission measurement pumps from KNF are based
on a simple principle ñ an elastic diaphragm,
fixed on its edge, moves up and down its central
means of an eccentric. Thus, the medium is transferred
via automatic valves.
new range of KNF pumps for the first time is
equipped with the patented stress-optimized
structured diaphragm, resulting in a durable
product of high pneumatic performance. Special
valves ensure minimum resistance to low.
and pump drives in this product series are explosion
proof according to 2014/34/eu (ateX) and iecex.
the high gas-tightness of the diaphragm system
is especially important for use in potentially

diaphragm vacuum pumps offer a high level of
performance, as well as an excellent price performance
ratio. They are required especially in the potentially
explosive ields of chemical, analysis, energy
and production technology.
pumps are used for transferring, compressing
and sucking air, gases and vapors, taking samples
(even liquids in a vacuum) and evacuating and
compressing vessels etc.
other applications, pumps are used for gas measurement,
for example for sampling gases out of the ambient
environment, or for exhaust gas and smoke analysis.
