Regular maintenance
Visual inspection of the power supply cables
The power supply cables must be examined for bubbles, cracks, scratches, chafe marks and/or crushing. If damage
is found, the damaged power supply cable must be replaced immediately.
Cables may only be replaced by the manufacturer or an authorised or certi昀椀ed service workshop. The pump may
only be put back into operation after the damage has been eliminated properly.
Visual inspection of the cable clips (snap hook) and rope anchor (pull cable)
If the pump is used in reservoirs and/or chambers, the hoisting cables / cable clips /snap hook) and rope anchor
are exposed to constant wear. Regular checks are necessary to prevent the hoisting cables / cable lips (snap hook)
and/or rope anchor wearing through fully and damaging the power cable.
The hoisting cables / cable clips (snap hooks) and rope anchor must be replaced immediately with the 昀椀rst signs
of wear!
Visual inspection of accessories
The accessories such as suspension devices, lifting gear etc. must be checked for their correct 昀椀t. Loose and/or
faulty accessories must be repaired or replaced immediately.
Visual check of pumps with oil boom chamber (model type without a cooling jacket)
Oil level and oil condition:
The condition of the 昀氀oating-ring type shaft seal can be checked by a visual inspection of the oil. Place the pump
horizontally so that the oil chamber control screw on the side of the motor casing (on larger pumps: one of the two
oil chamber control screws) is located at the top.
Remove the screw and extract a small amount of oil. If the oil is cloudy or milky, the shaft seal is probably defective.
In this case, have the KESSEL Factory Customer Service check the condition of the shaft seals.
Functional check of the safety and monitoring devices
Monitoring devices are e.g. temperature sensor in the motor, motor protection relay, overvoltage relay etc. Motor
protection, overvoltage relay and other actuators can generally be triggered manually for testing. In order to test the
temperature sensor, the pump must have cooled down to the ambient temperature and the electrical connection
cable of the monitoring device must be disconnected in the control cabinet. The monitoring device is then checked
using an Ohmmeter. The following values should be measured:
Bimetal sensor: Value equal "0" - passage
If there are major deviations, please contact the manufacturer.
Please refer to the relevant operating instruction for details of checking the lifting gear's safety and monitoring
devices.
