6. Description and operation
6.1 Pump description (Fig. 1)
The submersible motor pump is driven by an
enclosed motor that is impermeable to press-
water. Motor and pump have a continuous shaft.
The flow medium enters from below through the
central suction opening and exits by the vertical
pressure pipe connection. The pump has a built-in
non return valve (pos. 5).
The SBS 2-204 pumps are delivered with a half-
open impeller (pos. 23). It pumps solids up to 10
mm Ø (no fibrous materials such as grass, leaves
or rags).
For stationary installation, the pump is screwed to
a fixed pressure-pipe (R 1½), and for transportable
installation to a hose connection.
The motor of both types is sealed with a mechan-
ical tandem seal (pos. 20) on the medium and
motor side against the pump housing. So that the
seals are lubricated and cooled in the case of dry
running, the chamber between the mechanical
seals is filled with oil.
CAUTION! Risk of leak!
If the mechanical seal is damaged, small quan-
tities of oil may leak into the flow medium.
The motors are fitted with a thermal motor pro-
tection (1~: thermal winding contact (WSK), 3~:
thermal motor control) that automatically switch-
es the motor of if there is a threat of it overheat-
ing and switches it back on again once it has
cooled down. A capacitor is fitted at the 1~ motor
to generate the rotary field.
7. Installation and electrical connection
Installation and electrical connection should be
carried out in accordance with local regulations
and only by qualified personnel!
WARNING! Risk of personal injury!
The relevant accident precaution regulations
must be observed.
WARNING! Risk of electric shock!
Potential dangers caused by electrical energy
must be excluded.
Local or general regulations [e.g. IEC, VDE, etc.]
and directives from local energy supply compa-
nies are to be followed.
7.1 Installation
The pump is designed for stationary and trans-
portable wet-well installation.
CAUTION! Risk of damage to the pump!
• Only suspend the pump using a chain or rope
from the transport loop, never by the electric
cable or pipe / hose connection.
• When the pump is lowered into the shaft or pit
the connecting cable must not be damaged.
• The pump must be installed in a frost-free place.
• The shaft must be free from coarse solids (e.g.
building rubble) prior to installation and commis-
sioning.
• See catalogue for installation dimensions.
• The pressure-pipe must show the pump’s nomi-
nal width (R 1½, possibility for expansion).
7.1.1 Stationary wet-well installation
In the case of stationary wet-well installation of
SBS 2-204 pumps with pressure-pipe the pump is
to be positioned and secured such that:
• the pressure-pipe connections do not bear the
weight of the pump,
• the load of the pressure-pipe does not act on the
connecting sleeve.
7.1.2 Transportable wet-well installation
In transportable wet-well installations, the pump
in the shaft is to be protected against tipping over
and slipping. (e.g. secure the chain with slight
prestressing).
NOTE:
If used in pits without a solid floor, the pump
must be placed on a sufficiently large plate or
be suspended in a suitable position on a rope or
chain.
