Type Service instructions Lubrication Inspection
Electric motor All
Keep the motor housing clean
(otherwise cooling is affected).
The motor housing may only be
dismantled by Grundfos.
The roller bearings are
maintenance-free. They should be
replaced if they get noisy. For motors filled with dielectric
oil, oil level check and oil change
are not required.
Supply cable All
The supply cable must be
checked twice a year for surface
damage, strain, kinks, etc.
If damaged, the cable must be
replaced by Grundfos.
Gearbox All
Check the gearbox for leaks twice a
year.
Change the oil after 500 operating
hours.
Then every 8,000 operating hours
or after one year of operation.
Check lip seals, speedy sleeve and
wear ring and replace them in case
of wear.
If the oil contains water, replace the
mechanical shaft seal.
Check the oil level twice a year.
If refilling is required. See
section
9.3.2 Oil quantity
.
Impeller All
Check the impeller regularly for
wear and tear. Remove any
material wound round the
impeller, such as ropes, threads,
etc. which may cause uneven
running and oscillation of the
installation. In case of strong
turbulence, cleaning is
absolutely necessary.
Winch All
Spray the winch with a protective
coating of oil at regular intervals to
prevent corrosion. The gear teeth and the bearing
bushes must be lubricated twice
a year with an all-purpose grease.
Lifting wire All
Regular oiling or greasing
increases the life of the wire.
Check the wire regularly and
always before using the winch.
Replace the wire, if required.
Screws All
Always check that all screws in the
pump rack are properly tightened.
