1. General Information
Assembly and installation should only be carried out by quali-
fied personnel!
1.1 Uses
The Wilo synthetic shaft pumpstation WS is used together with a
submersile motor-driven pump from the Wilo Drain series to form a
complete pumpstation for the transportation of muddy water, waste
water and sewage in the field of building technology (in houses for one
or more families, basement garages etc.). It is used in applications
where waste water cannot be transported into the public sewerage
system by the natural gradient level. Due to the fact that this product is
not heavy, the shaft can be lowered into the ground without a hoist or
extra concrete work.

2. Safety
These instructions contain important information which must be
followed when installing and operating the pump. It is therefore
imperative that they be read by both the installer and the operator
before the pump is installed or started up. Both the general safety
instructions in the "Safety precautions" section and those in sub-
sequent sections indicated by danger symbols should be carefully
observed.
2.1 Instruction symbols in this operating manual
Safety precautions in these operating instructions which, if not
followed, could cause personal injury are indicated by the symbol:
Safety precautions warning of danger due to electricity are indicated
by the symbol:
The following symbol is used to indicate that by ignoring the relevant
safety instructions, damage could be caused to the pump/machinery

2.2 Staff training
The personnel installing the pump must have the appropriate qualifi-
cations for this work.
2.3 Risks incurred by failure to comply with the safety precautions
Failure to comply with the safety precautions could result in personal
injury or damage to the pump or installation. Failure to comply with the
safety precautions could also invalidate any claim for damages.
In particular, lack of care may lead to problems such as:
– Failure of important pump or machinery functions,
– Personal injury due to electrical, mechanical and bacteriological
causes.
2.4 Safety precautions for the operator
Current regulations on the prevention of accidents must be observed.
Injury resulting from electrical charges must be avoided. The VDE
(German association of Electrical Engineers) and national energy
supply company regulations must be observed.
2.5 Safety information for inspection and assembly
The operator must ensure that all inspection and installation work is
carried out by authorised and qualified specialists who have carefully
studied these instructions.
In principle, work should not be carried out on a running pump or
installation and a second person should always be present.
2.6 Unauthorized modification and manufacture of spare parts
Changes to the pump/machinery may only be made in agreement
with the manufacturer. The use of original spare parts and accessories
authorised by the manufacturer will ensure safety. The use of any other
parts may invalidate claims invoking the liability of the manufacturer for
any consequences.
2.7 Unauthorised operating methods
The operating safety of the pump or installation supplied can only be
guaranteed if it is used in accordance with paragraph 1 of the oper-
ating instructions. The limiting values given in the catalogue or data
sheet must neither be exceeded nor allowed to fall below those
specified.
3. Transport and storage
The unit is delivered together with the individual
ATTENTION!
components on a pallet. The pallet may only be
transported using permissible load suspension de-
vices. Please ensure that the pallet is stable at all
times. Do not suspend the pallet using the transport
eyelets on the plastic shaft. These are intended for
the transportation of the empty shaft. The pump
must be protected against mechanical damage.
4. Description of product and accessories
4.1 Description of the unit (Fig. 1 and 2)
The unit comprises a plastic shaft made of PE (Fig. 1, pos. 1). This
shaft is available in two sizes: WS 900 E for single pumps (Fig. 1),
WS 1100 E/D for large single or double pumps (Fig. 2). The hole-
shaped form of a part of the shaft walls and the "fins" prevent the
lifting of the pump. The following components are assembled in the
shaft for the connection of one or two submersile motor-driven
pumps:
– Stand for securing the submersile motor-driven pump with easily
removable surface coupling (Fig. 1, pos. 3)
– Pressure pipe connection with outer threads (W.-No. 1.4404 /
1.4571) (Fig. 1, pos. 13)
– Shut-off device (Fig. 1, pos. 5)
– Connection for flushing device (air or water), ventilation unit, mobile
emergency disposal unit or a industrial type pressure gauge (Fig. 1,
pos. 6)
– Cone-shaped backflow preventer (Fig. 1, pos. 4)
– Compressed air piping with flange of V 4 A (W.-No. 1.4404 / 1.4571)
for connecting the pump (Fig. 1, pos. 12)
