1. Safety instructions
1.7 Intended use
ATEX gerotor pump units of SKF series 143
are for supplying centralized lubrication sys-
tems with lubricant and are intended for use
in centralized lubrication systems. They feed
mineral and synthetic oils that are compat-
ible with plastic and FKM (FPM) elastomers.
The permissible operating viscosity for the
oils is 20 to 1000 mm
2
/s at a permissible
pumped medium temperature of 0 to 60 °C.
The assembly instructions in Chapter 6
must be adhered to. The information in
Chapter 4, “Technical data,” must be fol-
lowed as well.
Only media approved for these gerotor
pump
units may be used. Unsuitable media may
result in pump unit failure and potentially
severe bodily injury or death and property
damage.
The use of synthetic and biodegradable oils
requires prior approval from SKF.
Commissioning of the gerotor pump unit is
prohibited until such time as the final prod-
uct is determined to confirm with Directive
2006/42/EC.
1.8 Foreseeable misuse
Any usage of the pump differing from the
conditions presented in this manual and the
specified purpose is strictly prohibited. Par-
ticularly prohibited are use:
○
in another, more critical explosion pro-
tection
zone than specified in this manual
○
without a pressure regulating valve
○
outside the specified temperature range
○
in areas with aggressive, corrosive sub-
stances (e.g., high ozone loads); these
may corrode the seals and the finish.
○
in areas with damaging radiation (e.g.,
ionizing radiation)
○
To feed, forward, or store hazardous
substances and mixtures as defined in
Annex I Part 2-5 of the CLP Regulation
(EC 1272/2008)
○
To feed / forward / store gases, liquefied
gases, dissolved gases, vapors, or fluids
whose vapor pressure exceeds normal
atmospheric pressure (1013 mbar) by
more than 0.5 bar at their maximum
permissible operating temperature
○
overcoating the pump
1.9 Modifications to the product
Unauthorized modifications/changes can
have an unpredictable effect on safety. Un-
authorized modifications/changes are there-
fore prohibited.
1.10 Persons authorized to use
