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
must be replaced if they get
noisy.
Power
supply
cable
All
Check the power supply
cable twice a year for
surface damage, strain,
kinks, etc.
If damaged, the cable must
be replaced by Grundfos.
Gearbox
All
In case of wear, replace lip
seal and wear ring.
If the oil contains water,
replace the shaft seal.
Change the oil whenever it
contains water or is
contaminated. Change the
oil at least every two years.
If refilling is required, see
section
If the shaft seal housing is
not monitored for the
ingress of water, we
recommend that you make
inspections every 6
months.
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.
When tightening the
screws, renew the
threadlocker if necessary.
