7 Servicing/Maintenance
7.3.3 Checking the cable bundle
When removing the pump set from the discharge tube, check the hoisting rope and
the cables for any damage. Replace any damaged components by original spare
parts.
Longer sections of combined cables must be dismantled:
1. Remove the cables from the cable clamps.
2. Remove the spacer.
3. Roll up the cables and place them next to the pump set.
4. Undo the shackle to separate the support rope from the pump set.
7.3.4 Checking the earth conductor
1. Measure the resistance between earth conductor and earth.
The resistance must be below 1 Ω.
2. Replace any damaged components by original spare parts.
DANGER
Defective earth conductor
Electric shock!
▷ Never switch on a pump set with a defective earth conductor.
7.3.5 Checking the mechanical seal for leakage
WARNING
Fluids handled, consumables and supplies which are hot and/or pose a health
hazard
Hazard to persons and the environment!
▷ Collect and properly dispose of flushing fluid and any fluid residues.
▷ Wear safety clothing and a protective mask if required.
▷ Observe all legal regulations on the disposal of fluids posing a health hazard.
WARNING
Excess pressure inside the pump set
Risk of injury when opening the pump set!
▷ Take care when opening the inner chambers. Equalise the pressure.
NOTE
Slight wear of the mechanical seal is unavoidable. This will be aggravated by
abrasive substances contained in the fluid handled.
Checking the leakage chamber serves to assess the function of the drive-end
mechanical seal.
