2006/42/EC. The essential requirements of Annex I of Directive
2006/42/EC (general principles) are applied and observed.
The pumps comply with Directive 2014/34/EU concerning equip-
ment and protective systems for intended use in explosive atmos-
pheres, and with the standards Normen ISO 80079-36 and ISO
80079-37 for ex areas.
The "Directives for the prevention of risks from explosive atmos-
pheres with a collection of examples
– explosion prevention and
protection directives
– (EX-RL)" should be observed when classify-
ing a pump environment in an explosion-proof area.
In special cases or where there is doubt when defining potentially
explosive atmospheres, notify the supervisory authorities and ask
them to decide.
All repairs to the pump(s) must be carried out by the relevant KNF
Customer Service team.
Only use genuine parts from KNF for servicing work.
Safety concept
A risk analysis was carried out in accordance with EN 1127-1.
Ignition sources
If the pump compresses against the maximum permissible operat-
ing pressure, the temperature of the head will not exceed the
maximum surface temperature because the head is able to transfer
heat to its environment. The pump's environment must therefore
be adequately ventilated.
The projected surface area of the non-conductive parts which may
become electrostatically charged is less than 100cm
2
. The total
surface area of electrically insulated metal disks is very small, in
addition to which the screw heads are countersunk in the pump
head. As a result there should be no risk of ignition from the elec-
trostatically chargeable parts.
As a result of the material used inside the pump, the possibility that
critical material combinations may come into contact is excluded.
In addition, these are mounted pumps, which should preferably be
installed in housings and are made of plastic.
The nuts and bolts used are made of stainless steel, so contact
with critical materials is unlikely.
