Grooves 1, 2 and 10 may not be used.
3.
Insert the O-ring supplied in the selected groove in the extension.
4.
Coat the O-ring and the inside of the taper on the pump chamber
with lubricant (washing-up liquid or even water in an emergency).
5.
Slide the pump chamber extension into the pump chamber until the
O-ring wedges securely in the cone in the taper.
Do not push the O-ring beyond the cone. Make sure that the
O-ring slides cleanly into the taper, does not twist and is not
pushed out of the groove. If necessary, push the O-ring further by
hand when fitting the extension.

6 Surface level substructure
Standard concrete adjusting rings can be used for height compen-
sation to the surface level, up to a maximum of 200 mm above the
top edge of the pump chamber including the pump cover height.
The concrete rings should be provided by the customer.
1.
1. Place the concrete ring centrally on the cover flange
2.
Fill the gap between the concrete ring and the cover flange with
sand or mortar.
3. Place further concrete rings centrally.
To ensure a solid and full-faced contact between the concrete rings
and the cover frame and to minimise additional water ingress by
ground water or surface water, a thin layer of mortar must be applied
to the mating surfaces on the concrete rings and the cover frame.
5.2.6. Installing the pump chamber extension – When using D400 pump
cover
CAUTION!
The max. installation depth of 2750 mm including load distribu-
tion plate, concrete adjusting rings and pump cover may not be
exceeded. Otherwise, deformation or cracks in the body of the
pump chamber could occur.
CAUTION!
When using the load distribution plate, absolute impermeability
to the interior of the pump chamber is not achieved. This can
lead to increased ingress of water into the pump chamber at
a high ground water level. In turn, this can overload the pump
and cause consequential damage to the pumping station.
