Description; Putting Into Operation - Bauer Magnum S Operating Manual

3 DESCRIPTION

The submersible motor pump MAGNUM S consists of a three-phase submersible motor with connecting cable,
and oil chamber, and the pump housing with cutter and impeller. The electric motor flanged onto the pump
housing has a motor output of 4 / 5.5 / 7.5 / 11 or 15 kW, depending on the respective model.
To motor is equipped with PTC thermistor detectors to protect if from overheating. Therefore the motor
protection will only be effective if the motor connecting cable is linked up not only with a star-delta starter but
also a suitable thermistor trip device.
The control box that is available as motor accessory, includes not only the starting contactor but also the
thermistor trip device. The red alarm lamp lights up when the thermistor tripping device has been actuated
!
NOTE
WARNING!
The motor is sealed by two mechanical seals mounted in series. The mechanical seal on the motor side is
lubricated only by the oil contained in the oil chamber, while the mechanical seal on the impeller side is
lubricated by the pumped medium in addition. The bearing of the SUBMERSIBLE MOTOR PUMP is life-
lubricated.
Apart from pumping liquids into other tanks, the submersible motor pump M S can also be used for stirring the
pit content.
For this type of operation the equipment and fittings such as delivery line, delivery socket and elbow are
replaced by a nozzle with optional 50 or 80 mm diameter mounted on the pump housing.
