6. DESCRIPTION AND OPERATION
6.1 Pump description
In order to ensure that the pump remains sufficiently cool in
continuous mode, the submersible motor-driven pump must
always be flooded with the flow medium. The pump is driven
by an encased three-phase or single-phase motor which is cor-
rosion-resistant and impermeable to pressurised water.
The pump housing and single-channel impeller are made from
grey cast iron. The flow medium is sucked in on the underside
of the pump through the openings on the cutting device and
is expelled through the discharge side into the pipe.
The cutting device cuts up all dissectible constituents so that
they can be transported through the single-channel impeller
and the DN 40 pressure pipe. The blades, cutters and counter-
cutters are made of hard metal. Constituents which cannot be
cut, such as stones or pieces of metal, damage the cutting
device and should therefore not be allowed into the pump.
The motors are sealed from the flow medium by means of a
mechanical seal. Sealing from the oil chamber is also by
means of a mechanical seal on types SDL i, whereas a shaft
seal is used on types MINI SDL.
The oil chamber serves to cool and lubricate the seals (see also
5.2).
CAUTION! Risk of leak!
If the mechanical seal is damaged, small quantities of
oil may leak into the flow medium.
In addition to being connected by a foot bend DN 40, the SDL
pumps can also be connected to the pressure pipe using an
elbow pipe (inner/outer thread):
• MINI SDL, SDL i: DN 32 (R1 ¼)
• SDL i: DN 40 (R1 ½) and threaded flange with neck as per DIN
2566
The motors are equipped with a winding protection contact
(WSK) that automatically switches off the motor if there is a
threat of it overheating and switches it back on again once it
has cooled down. On 3~motors, the winding protection con-
tact must be connected to the switchgear and analysed
there.
7. INSTALLATION AND ELECTRICAL CONNECTION
Installation and electrical connection should be carried out in
accordance with local regulations and only by qualified per-
sonnel!
WARNING! Risk of personal injury!
The relevant accident precaution regulations must be
2
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 companies are to
be followed.
