Stator tube with
1
non-return valve
2 Eccentric shaft
Required to correctly assemble single components:
• M17 open-end wrench (Fig. 3b, item 1)
• M10 open-end wrench (Fig. 3b, item 2)
• Thread adhesive (within scope of delivery) (Fig. 3b, item 3)
Assembly
1. Apply thread adhesive to the female thread of the eccentric screw (Fig. 3c).
2. Manually screw on the eccentric shaft onto the flexible drive shaft (Fig. 3d).
3. Tighten the eccentric shaft using the M17 open-end wrench and in this process use the
M10 open-end wrench to counter on the flexible drive shaft (Fig. 3e).
4. Apply thread adhesive to the female thread of the stator tube (Fig. 3d).
5. Coat the eccentric screw with clean water (Fig. 3g).
CAUTION: beware of damage!
It is necessary to coat with clean water so it is pos-
sible to slide on the stator.
In any other case the friction resistance between
rubber stator and eccentric screw would prevent
sliding on the progressive cavity or cause damage.
Do not apply adhesive to the eccentric screw!
6. Manually slide the stator tube over the eccentric shaft and slide onto the connecting
pipe (Fig. 3h).
7. Position the pump wrench on the non-return valve and tighten the stator tube by hand
to fasten the connection (Fig. 3i).
CAUTION: beware of damage/malfunctions!
Wait a minimum of 60 minutes before starting up
the pump (Fig. 3j).
In any other case threads may come loose and cause
malfunctions or damage to the pump.
