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.
