1.7 Explosion protection information
Danger!
Only the pump models tested and
approved by SKF Lubrication Systems
Germany GmbH in accordance with
ATEX Directive 2014/34/EU are permit-
ted to be used in areas with explosion
protection. The relevant class of protec-
tion is engraved on the pump's rating
plate.
When illing lubricant into the pump,
make sure the lubricant is clean. The
reservoir must be illed in good time (pay
attention to ill level monitoring). Lubricant
must be illed only via the iller socket
G 3/8“ (FF) or G 1/2“ (FB) on the pump
lange. Lubricant may only be illed via
the "reservoir cover" if absolutely certain
that no potentially explosive atmosphere
exists.
In case of overilling, the excessive
amount of lubricant must be removed.
Make sure there is no potentially explosive
atmosphere when doing this.
The switching circuits of the ill level
monitor must be supplied by an intrinsi-
cally safe circuit, e.g., through the installa-
tion 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-
resistant 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 oil lubrication pump
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 conjunc-
tion 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).
