Danger!
Only the pump models tested andap-
proved by SKF Lubrication Systems
Germany GmbH in accordance with
ATEX Directive 2014/34/EC are per-
mitted to be used in areas with explo-
sion protection. The relevant protection
class is engraved on the pump's rating
plate.
sure the lubricant is clean. The reservoir
of lubricant must be removed. Make sure
there is no potentially explosive atmosphere
when doing this.
-
itor must be supplied by an intrinsically
safe circuit, e.g., through the installation
of an ATEX-compliant isolating switch by
the customer.
The unit must be grounded via a ground
connection. The customer must install ad-
equate overload protection for the power
consumption of the motor.
To avoid electrostatic discharge, lay
hydraulic connecting lines in corrosion-re-
sistant metal tubing, e.g., stainless steel pipe.
When setting up the pump, make sure the
setup location is level and not subject to
vibrations or jolts.
During maintenance work, use only tools
intended for use in potentially explosive
spaces or else make certain that there
is no potentially explosive atmosphere
present.
The service life of the pump units is
limited. It must therefore undergo a
function and leak test at regular intervals.
Perform appropriate repairs in the event
of malfunctions, leaks, or rust. Replace
the pump if necessary.
The user must make sure through the
choice of the lubricant to be delivered that
no chemical reactions capable of serving
as ignition sources will occur in con-
junction with the explosive atmospheres
expected.
The lubricant’s ignition temperature has
to be at least 50 kelvin above the pump’s
maximum surface temperature (tempera-
ture class).
Depending on the model design, the product
may be available in an explosion-proof design.
