1.11 Instructions concerning explosion protection
The instructions below are to be considered and kept to when using
pumps in potentially explosive areas in order to guarantee durable
explosion protection of the pumps and avoid any danger of ignition.
In accordance with the regulations 94 / 9 / EC, the pumps are admitted
for use in the area II 2G IIB T 4 or II 2G IIB T 3
(pls. see manufacturer’s declaration or declaration of conformity).
It is to be taken into account that in case of aggregates the components
(e.g. gears, couplings) mounted on the pumps must comply with the
regulations 94 /9 / EC as well. The relevant documentation concerning
these components is to be considered.
The application area of aggregates is determined by the application area
of the mounted component with the lowest approval and thus may
deviate from the allowed application area of the pump.
The maximum conveying product temperatures apply when mechanical
seals of Messrs. Burgmann with carbide – carbide and carbide – carbon
as sliding material combinations are used.
In the case of other manufacturers or other sliding material combinations
it is necessary to consult the manufacturer.
1. Assembly and repair in potentially explosive areas
When performing assembly and repair work, it is to be seen to it that
no dangers of ignition arise especially during heating up the pump parts.
This means e.g. heating up by explosion-proof heating devices or exclusively
in non-explosive areas. The temperature of the heated part and the ignition
temperature of the materials by which the danger of explosion may be
caused are to be considered.
2. Dry-running protection
Under no circumstances is the pump to run dry.
The pump is to be equipped with an appropriate dry-running protection
device.
