Your
pool pump will
require service to
two main items:
Mechanical
Seal:
This item is
situated between the
pump wet end & the
electric motor &
form the seal around
the the motor shaft
to stop water coming
back along the
shaft.
The mechanical seal
is a wearing part &
will normally
require replacing
each 2-3 years or
earlier if necessary
The seal will burn &
leak if the pump is
ever run dry. Always
replace the seal as
soon as it begins to
leak.
Replacement is done
by disconnecting the
water & electrical
connections & then
removing the wet
end, remove the old
seal & replace with
a new one, be
careful not to break
the ceramic face of
the new seal when
refitting.
Motor
Bearings:
These bearings are a
wearing part & would
normally be replaced
each 4-6 years.
The bearings will
start to grind or
scream as they
become dry or if
water leaks through
the mechanical seal
& flushes the grease
out of them.
Best to disconnect
the water &
electrical
connections for the
pump & motor &
remove the wet end,
then take the motor
to a motor re-winder
who can replace the
bearings for you. It
is better done where
they have bearing
pullers & presses
