Shaft seal
The Aqualine series is equipped with a combination of
seals with grease barriers especially developed for this
application.
The grease barrier of this seal needs regreasing with
the above special lubricating grease in regular inter-
vals of 200 – 300 operating hours. The lubricating nip-
ples are located on the bearing caps on both faces of
the liquid ring pump.
Regrease the machine when it is cold; apply grease
until it emerges from the vent valve (see figure 1.3).
The amount of grease is approx. 10 – 15 grams on
each side. If access to the lubricating nipples is diffi-
cult, an extension of the lubricating line by maximum
0.5 m and 6 – 8 mm diameter may provide easier ac-
cess.
If the operating water has a high pollutant content (es-
pecially solvents) regreasing may be required more of-
ten. The actual intervals are determined by experience.
Caution!
Connecting the Aqualine lubrication to the cen-
tral lubrication of the vehicle is not allowed!
A mixture of grease-water vapour can emerge
from the grease nipple at fist start-up or after
extended downtime, occasionally steam in nor-
mal operation.
