domestic use (potable water supply)
agricultural use (watering, irrigation),
• Pumped liquids: non polluted, potable, cold, rain
waters.
The pump is not suitable for continuous use, e.g.
for the operation of fountains.
(Continuous operation > 2 hrs reduces the life-
time of the pump).
The pump must not be used for emptying swim-
ming pools.

5.6 Design of pump and motor
The submersible pump is of the multi-stage,
centrifugal design.
All parts in contact with the flow medium are of
either corrosion-resistant material.
The electric motor is protected of the hydraulic
part pump by two mechanicals seal and a oil
chamber for maintained the tightness of the
motor.
The pumps are supplied with a carrying rope.
The pump base contains a suction strainer.
The SE type model are fitted with a suction sup-
port to allow the connection of floating or fixed
suction filters, together with a stand including 4
vibration absorbers for installation on the ground.
The single-phase motor pumps (EM) are deliv-
ered ready for connection with a switchbox. It
contains:
• Cut-out switch with indicator light,
• Built-in over current trip device in manual reset,
• Motor capacitor,
• Connection for a float switch (Low-water - / Dry
running protection),
• Cable connected to the terminal box as well as to
the pump,
• Connected 1 m long mains cable with shock-
proof plug.
The motor is fitted with a winding protection
which automatically switches the motor off if it
overheats and on again once it has cooled down.
Three-phase pumps (DM) are supplied with bare
cable lead ends.
The switch box can be ordered from the Wilo
range or provided by the customer.
It must be fitted with a motor safety switch.
Once the over current protective device has been
triggered the fault must be reset by operating
the cut-out switch.
