4 Intended use
Wilo-Drain STS 40 submersible pumps are suitable
for pumping sewage, waste water and clean fluids
containing solid particles of up to 40 mm diameter
from shafts, pits and containers.
They are used for the following applications:
• Domestic drainage
• Sewage and water supply
• Environment and waste water treatment
• Industrial and process engineering
NOTE: Follow the locally applicable regulations for
the intended application.
The pumps are usually installed flooded
(immersed) and can only be installed vertically,
whether fixed or mobile.
Submersible motor pumps with connection lines
of less than 10 m are only approved (according to
EN 60335) for use within buildings, not for out-
door use.
DANGER! Risk of fatal injury!
The pump may not be used to empty swimming
pools / garden ponds or similar locations if there
are people in the water.
WARNING! Health risk!
Owing to the materials used, the pumps are not
suitable for drinking water! Dirty water poses a
risk to health.
CAUTION! Danger of material damage!
Pumping materials which are not approved can
lead to damage to the product.
The pumps are not suitable for water containing
coarse impurities such as sand, fibres or flam-
mable liquids, or for use in areas at risk of explo-
sion.
Use of the product as intended also means follow-
ing these instructions.
Use over and beyond the use described is not use
as intended.
