Watson Marlow Pumps 620RA ATEX Bedienungsanleitung Seite 10

The pump must be accessible at all times to facilitate operation and maintenance. Access points must not
be obstructed or blocked.
If hazardous fluids are to be pumped, safety procedures specific to
the particular fluid and application must be put in place to protect
against injury to persons.
Ensure the chemicals to be pumped are compatible with the
pumphead, lubricant (where applicable), tubing, pipework and
fittings to be used with the pump. Please refer to the chemical
compatibility guide which can be found at: www.wmftg.com/chemical.
If you need to use the pump with any other chemical please contact
Watson-Marlow to confirm compatibility.
Explosion hazard. Failure to comply may cause severe or even fatal
injuries.
All work, e.g. transportation, storage, installation, connection,
commissioning, servicing and maintenance must be performed in a
non-explosive atmosphere.
Always check to ensure that an Exd motor gearbox is suitably rated for
the hazardous zone area in which it is to be used, including ATEX, Ex
and any other hazardous area legislation for the country in which it is
being installed. Exd motors should only be installed by Exd qualified
personnel.
Primary operator protection from rotating parts of the pump is
provided by the pumphead guard. Note that pumphead guards differ,
depending on the type of pumphead.
