Stator and rotor are wear parts. Their service life largely
depends on the prevailing conditions.
The residual liquid must be emptied through the outrun
piece, before dismounting.
In order to dismantle the stator, the pump foot must
be unscrewed and pulled o forcibly. Force the stator
out of the pump foot (stator sleeve). The soiled screw
thread on the pump tube and stator sleeve must be
cleaned and lightly greased.
To replace the stator, place the rst thrust ring in the
stator sleeve, force the new stator into the stator sleeve
and place the second thrust ring onto the stator. Note
the nose and notch on the sleeve and stator when
replacing solid stators. Screw the stator sleeve onto the
pump tube.
Repairs should only be made by the manufacturer or
authorized Lutz-dealers. Only use original Lutz spare
parts.
Before sending back the appliance, following must be
observed:
• Residuals in the appliance can cause danger to the
environment and human health. The appliance must
be completely emptied, rinsed and cleaned.
