3 Transport and interim storage

On receipt of the product, check immediately for
transport damage. If any transport damage is
found, initiate the necessary procedure with the
forwarding agent within the period specified.
CAUTION! Danger of property damage!
Incorrect transport and incorrect storage can
lead to damage to the pump.
• When transporting, only carry or suspend the
pump by the handle/holder. The cable should
never be used for lifting!
• When transporting and storing the pump, pro-
tect it against moisture, frost and mechanical
damage.

4 Intended use

The submersible pumps Wilo-Drain STS 65 are
suitable for pumping polluted water and sewage
containing air, long-fibre solids, light faeces or
sludge (up to 10 % dry mass).
They are used in:
• domestic and site drainage
• sewage and water management
• environmental and water treatment technology
• industrial and process engineering
As a rule, the pumps are used in standard sumps:
• Single pumping station: diameter up to Ø1.5 m or
1 m x 1 m
• Double pumping station: diameter up to Ø2.5 m or
2 m x 2 m
Operating mode S3-25 % means over a period of
10 minutes:
• Operation time 2.5 min.
• Standstill time 7.5 min.
In this operating mode, the pumps can be oper-
ated with/without cooling jacket with the motor
on the surface and with the following switching
levels.
• Switch-off level: top of pump housing
• Switch-on level: top of motor
If used in basins with bigger cross-sections (e.g.
rainwater storage basins), the pumps
• must be operated submerged without cooling
jacket,
• submerged or on the surface with cooling jacket.
DANGER! Mortal danger through electric shock!
The pump must not be used for draining swim-
ming pools, garden ponds or similar installations
if there is someone in the water.
WARNING! Health hazard!
Owing to the materials used, the pumps are not
suitable for potable water! Unpurified wastewa-
ter is a health hazard.
CAUTION! Danger of property damage!
Unpermitted substances in the fluid can destroy
the pump. Abrasive solids (e.g. sand) increase
pump wear.
Pumps without an Ex certificate are not suitable
for use in potentially explosive areas.
Correct use of the pump/installation also includes
following these instructions.
Any use over and beyond these is interpreted as
incorrect use.
