4.1.1 SHS.../SBS...
The submersible motor pumps are suitable for pumping:
- waste water with impurities with max. Ø 10 mm
- condensate pH < 4.5
- distilled water
- weak acidic/alkaline liquids in certain conditions
- partially desalinated water in certain conditions
in
- building and property drainage systems
- environmental and waste water treatment technology
- industrial and process technology
The submersible motor pumps must not be used for pumping:
- waste water with coarse impurities
- sewage/feces
- raw sewage!
4.1.2 SCA.../SVO...
The submersible motor pumps are suitable for pumping:
- waste water
- sewage (feces restricted)
- partially desalinated water
- condensate pH < 4.5
- distilled water
- weak acidic/alkaline liquids in certain conditions
in
- building and property drainage systems
- sewage disposal (not covered by DIN EN 12050-1)
- water management
- environmental and waste water treatment technology
- industrial and process technology
The 1.4404 X-version can also be used for pumping:
- condensate
- partially desalinated and distilled water
- liquids with levels of chlorine up to 400 mg/l
4.2 Construction
The SHS, SBS, SCA, SVO is a floodable submersible motor
pump, which can be operated as both a stationary and porta-
ble wet installation.

4 Hydraulic housing
4.2.1 Hydraulics
SHS.../SBS...:
The hydraulic housing and the impeller are made from a syn-
thetic material (PP-GF30 or PUR). The discharge-side connec-
tion is designed as a vertical threaded flange. Semi-open,
multiple-channel impellers are used.
SCA.../SVO...:
The hydraulic housing and the impeller are made from a syn-
thetic material (PP-GF30 or PUR). The discharge side connec-

tion is designed as a horizontal flange connection. Semi-open,
single-channel or free-flow impellers are used.
The product is not self-suctioning which means that
the pumped liquid must flow in on its own.
Beware of static electricity!
Static electricity may be produced with plas-
tic materials. This can give you an electric
shock.
4.2.2 Motor
The motor is a dry run motor and made of stainless steel. The
motor is cooled by the pumped liquid and the heat is trans-
ferred via the motor housing to the surrounding fluid. The unit
must therefore always be submerged when operated. It can be
used continuously or in intervals.
Furthermore, the motor is equipped with a thermal motor moni-
tor (WSK). This protects the motor winding from overheating.
On the units SHS 205...M (1~230 V/50 Hz), it is integrated and
self-switching. This means that the motor is switched off when
it overheats and automatically switched back on after it cools
down.
The connection cable is available in different versions:
- With free cable end
- Version "BF" for 1~230 V/50 Hz with float switch, capacitor
box and Schuko plug
- Version "BF" for 3~400 V/50 Hz with float switch and CEE
plug
- Version "CEE" with CEE plug
Note the IP protection class of the CEE plug.
4.2.3 Sealing
The sealing to the pumped liquid and to the motor compart-
ment depends on the type:
- SHS.../SBS...: With a mechanical shaft seal on the liquid
side, with a rotary shaft seal on the motor side
- SCA.../SVO...: With a mechanical shaft seal on the liquid
side, with a rotary shaft seal on the motor side
The sealing chamber between the seals is filled with medicinal
white oil. The sealing chamber is fully filled with white oil when
the product is assembled.
4.2.4 Float switch
With the "BF" version, the float switch is connected to the
capacitor box / CEE plug.
The float switch makes it possible to set up a level-control sys-
tem which switches the unit on and off automatically.
4.3 Explosion protection in accordance with
ATEX
The motors are certified for use in environments where explo-
sions may occur, in accordance with directive
94/09/EC, and which require electrical devices in device group
II, category 2.
The motors can be used in both zone 1 and zone 2.
These motors may not be used in zone 0!
