2 GENERAL
BAUER products are designed and manufactured carefully and subject to a system of continuous quality control.
The submersible motor mixers fully meet the requirements of the agricultural practice and of biogas plants. They
are best suited for homogenizing all kinds of slurries from thin liquid manure to viscous mixtures containing solids
such as straw, fibres or clots. Short set-up times, easy handling and maximum performance reliability are further
advantages of this mixer series. Mixer drive is electric by means of a three-phase submersible motor.
Before turning on a submersible motor mixer make sure net voltage complies with the data on the nameplate.
In order to be able to work efficiently with the maintenance-friendly submersible motor mixer it is helpful to operate
it in connection with a hoisting device.
Although the mixer is simple in design you should study this manual carefully and strictly observe all operating and
service instructions contained. On this condition your motor mixer will operate to your full satisfaction for many
years!
Make this manual available to all operators handling the equipment. Serial number and mixer type are stamped
into the nameplate. Please specify these data in your inquiries, correspondence, warranty matters and parts
orders. We warrant for this pump according to our General Terms of Sale.
3 DESCRIPTION
The submersible motor mixer consists of a three-phase submersible motor with connecting cable, oil chamber, the
planetary gear drive and the propeller. The electric motor has an output of 7.5, 11 or 15 kW, depending on the
respective model.
The motor is equipped with PTC thermistor detectors to protect it from overheating. Yet the motor protection will
only be effective if the motor connecting cable is linked up not only with a star-delta starter but also with a suitable
thermistor tripping device.
Thus the motor is protected from phase failure, undervoltage and high thermal load.
The control box that is available as part of the motor accessories, includes not only the starting contactor but also
the thermistor tripping device. The red warning light lights up when the thermistor tripping device has responded.
NOTE
!
The motor cable should be mounted to the control box only by a qualified technician.
Check-up must be performed
according to the wiring diagram! The wiring diagram is
placed inside the control box. The control box must be tightly screwed and should
preferably be installed under a roof where it is protected from the weather.
When connecting the system to power supply ensure the connecting cable is amply
dimensioned and the turning direction of the motor is correct.
The motor is sealed by two mechanical seals mounted in series which are lubricated by the oil contained in the oil
chamber. The bearing of the THREE-PHASE SUBMERSIBLE MOTOR is life-lubricated.
The submersible motor mixer MSXH is equipped with a leak detector which is only effective together with a relay
mounted into the control box. (see chapter Accessories - Bauer Control Unit)
