Clean the sealing surface and firmly reinstall the oil-drain plug (5.1/2) or
(5.1/4) using a gasket which is in perfect condition. Wipe off any oil residues
from the casing.
Fill in new oil at a pump temperature of 15 ºC to 25 ºC. For this use a clean
funnel.
For oil quantities and ordering data see Sections 3.1.1 and 1.4.
Make sure to use the right kind of oil. PFPE pumps are marked with a red
label.
Only use Leybold oil.
Mineral oils, synthetic oils and PFPE do not mix.
Please consult us if you intend to run the pump with other oils or special
lubricants.
The oil filling levels stated in Fig. 3.2 to 3.5 - which apply to the shutdown
(standing still) pump - must be observed.
The filling level visible in the oil-sight glass depends on the size of the pump
and the type of oil used.
If the oil level is too low, the bearings and gearwheels are not lubricated
adequately; if it is too high, oil may enter the pumping chamber or the
pump may overheat.
Clean the oil-fill port and reinstall the plug (5.1/3) using a gasket which is in
perfect condition. Wipe off any oil residues from the casing.
5.3 Cleaning the Fan Cowl and the Cooling Fins
Observe all safety information provided in Sections 0.3 to 0.5 and 5.1.
The slits in the fan cowl as well as the fins on the motor and on the pump
may be contaminated depending on humidity conditions and the degree of
contamination in the ambient air.
In order to ensure a sufficient air flow for the motor and the pump’s casing,
the grid of the fan cowl must be cleaned with a clean brush when contami-
nated.
Any coarse dirt must be removed from the fins on the motor and the pump.
