NOTE
Paraffin oil is bright and transparent in appearance. A slight discolouration, caused
by the running-in process of new mechanical seals or small amounts of leakage
from the fluid handled, has no detrimental effect. However, if the lubricant is
severely contaminated by the fluid handled, this suggests a defect at the
mechanical seals.
