When assembling the pump in the machine/system it is the builder's responsibility that the parts used
conform to the ATEX directive and that the components are assembled and running according to the
operational data/design found in product data sheets and instructions.
Only use the pump as required by the explosion protection shown on the name plate.
Always ensure that the following is maintained:
•
The supporting frame, chassis, or structure of equipment containing the pump shall be constructed
of electrically conducting material and shall be so arranged as to provide a leakage path to earth
(ground) for any static electricity which occurs on the pump.
•
It is compulsory to use oils whose inflammable degree is at least 50K above the maximum surface
temperature of the pump. Maximum surface temperature is 200° C for Group 11G.
•
Make sure that all type of accessory installed on the pump are ATEX specified and have been installed
in accordance with ATEX requirements.
•
There are no creeping metal elements external to the pump.
•
There are no plastic parts that might accumulate electrostatic; or they are shielded.
•
The maximum permissible oil and ambient temperature is monitored and not exceeded for the
category and temperature class of the associated zone.
Manufacture the assembly flange on the machine/system where the pump has to be installed: the
relevant surface has to be perfectly smooth, completely de-greased and non-deforming.
It is necessary to verify the perfect alignment between the pump input shaft and the counter part – the
fitment between pump shaft and application's driven shaft must be executed so that no radial or axial
pre-load is generated – these extra loads reduce the bearings expected lifetime.
