Caution for pumps with tubular rotors:
Where the walls of tubular rotors are worn in the
wear zones, pumping medium may occur inside the
rotor and may come out when pulling off the
stator.
Ensure that protective measures have been taken
when pumping dangerous media!
Pull the stator (3005) out forward.
A stator extractor can be supplied as special
accessory.

Assembly
Refitting is a simple reversal of this procedure.
When refitting the stator (3005) check direction of
stator (3005) is correct! The funnel-shaped inflow
side (E) of the stator (3005) must show to
– the pump housing (2010) when rotation is
anti-clockwise
– the end stud (2005) when rotation is clockwise
when viewed on pump shaft end.
Elastomer stators (A) have integrated front side
sealing profiles (D). They don't need additional gas-
kets for sealing off the end stud (2005) and the
pump housing (2010).
Solid stators (B) have no integrated front side sea-
ling profiles. Therefore additional gaskets (8005)
should be installed to seal off the end stud (2005) as
well as the pump housing (2010).
