Submersible mixer with self-cleaning propeller (4) for mixing and keeping in
suspension municipal or industrial waste water and sludges.
Driven by the motor, the propeller (4) generates thrust for mixing the fluid handled.
The motor is monitored by means of temperature sensors (8) and leakage sensors (9).
The submersible mixer shaft (7) is equipped with two bi-rotational mechanical seals
(5) in tandem arrangement. A lubricant reservoir between the mechanical seals
ensures cooling and lubrication.
The cable gland (3) is totally watertight.
