Lubricants posing a health hazard and/or hot lubricants
Hazard to persons and the environment!
 When draining the lubricant take appropriate measures to protect persons and the
environment.
 Wear safety clothing and a protective mask if required.
 Collect and dispose of any lubricants.
 Observe all legal regulations on the disposal of fluids posing a health hazard.
Excess pressure in the lubricant reservoir
Liquid spurting out when the lubricant reservoir is opened at operating temperature!
 Allow the pump set to cool down to ambient temperature.
 Carefully pull off the mechanical seal.
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 coolant is
severely contaminated by the fluid handled, this suggests a defect at the
mechanical seals.
