Description
Pump with vortex impeller and vertical pressure connection. Surface-cooled AC or
three-phase current motor with self-switching thermal motor monitoring. The motor
heat is transferred directly to the fluid via the motor housing. The motor may emerge
during operation. The motor is switched off if it overheats and will be automatically
switched on again once it has cooled down.
For the protection of the motor, there is an oil separation chamber with a double seal
between the motor and the pump. A rotary shaft seal is built in on the motor side, and
there is a mechanical seal on the pump side. The oil separation chamber is filled with
oil to ensure the necessary lubrication of the seals.
