WARNING! 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! Polluted waste water presents a
health risk.
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 faeces, flammable liq-
uids or for use in areas at risk of explosion.

6. DESCRIPTION AND FUNCTION
6.1 Description of the pump (See FIG. 2)
The pump can be completely immersed in the liquid to be
pumped. The pump housing is made of plastic. The electric
motor is protected from the pump cavity by a shaft seal ring
sealing the oil cavity and by a mechanical seal which seals the
oil cavity from the water. To ensure that the mechanical seal is
always lubricated and cooled, even when running dry, the
mechanical seal chamber is filled with oil.
The motor is cooled by the surrounding fluid.
The motor is equipped with integrated motor protection, which
switches off on overload and automatically switches on again
after cooling down.
The pump is installed on the base of a shaft. When in a fixed
installation it is screwed to a fixed pressure line. For a mobile
installation it is connected to a hose.
The pump is operated by plugging in the power supply plug.
If the waste water line does not allow any interruptions, then a
2nd pump (automatic standby pump) in conjunction with the
necessary switchgear (accessories) increases the reliability in
case of a fault with the 1st pump.
6.2 The pump functions
Pump with a float switch:
The „MINI SUBSON MF...“ (See FIG. 1) pumps work automati-
cally in that a float switch turns the pump on, via the free cable
length, once the water reaches a certain level and turns it off
again when it reaches a minimum water level. Level suction to
5 mm (See FIG. 1).
Pump without a float switch:
The versions without a float switch are suitable for use with
external switching, for example using switchgear (accessories).
Example : MINI SUBSON M, MINI SUBSON MF
MINI SUBSON MP, MINI SUBSON MFP
MINI SUBSON : submersible pumps
M : single-phase (monophasé)
F : with float switch
P : portable version (10 m cable)
