±
10% of the rated voltage
Impeller inspection
➢
If the performance level has decreased considerably
,
the impeller
may be worn
Semi-annually
Lifting chain or rope inspection
Oil inspection
(see chapter
5.4. Oil inspection and change
)
Yearly
Oil change
(see chapter
5.4. Oil inspection and change
)
Mechanical seal replacement
➢
Every 6000 hours or 12 month, whichever comes first.
NOTICE:
Contact Tapflo for mechanical seal replacement.
Once every 2
to 5 years
Overhaul
➢
The pump must be overhauled even if the pump appears normal
during operation. The pump may need to be overhauled earlier if
it
is
used continuously or repeatedly.

5.3.
Storage after operation
If the pump will not be operated for a long period of time, pull the pump up, allow it to dry,
and store it indoors. For storage recommendations see chapter
2.4. Storage
.
NOTICE:
Be sure to perform a trial operation before reinstalling the pump. If the pump remains
immersed in water
,
operate the pump on a regular basis (i.e. once a week) to prevent the
impeller from seizing due to rust.
5.4.
Oil inspection and change
Oil inspection
➢
Designated oil: Turbine oil VG32
➢
Oil volume: specified volume
➢
Inspection interval: every 3000 hours or 6 months,
whichever comes first.
➢
Changing interval: every 6000 hours or 12 months,
which ever come first.
Remove the oil plug and take out a small amount of oil. The oil
can be extracted easily by tilting the pump so that the oil plug
faces downward
.
If the oil appears discolored or intermixed with
water
,
a likely cause is a broken or worn mechanical seal
,
which
requires that the pump be disassembled and repaired.
Oil change
Remove the oil plug and drain the oil completely. Pour a
specified oil volume into the oil filler inlet.
