Sewage Mixers

Equipment for sewage treatment plants

Submersible mixers

Submersible mixers cause stream mixing of the medium in the tank and are mainly used in sewage treatment plants. They are intended to set the fluid in motion, homogenize its composition, prevent sedimentation, cause a specific flow direction and liquid circulation in tanks, ditches and channels. They are also often used in sewage aeration chambers as a support for intensifying oxygen absorption.

General characteristics of propeller stirrers for wastewater

  • The 3-blade propellers of sewage mixers from Metalchem-Warszawa are characterized by high hydraulic efficiency and have self-cleaning ability.

  • All mixers can be additionally equipped with a cover ring reinforcing the hydraulic mixing effect.   

  • The motor for direct drive with the number of poles from 4 to 8, for continuous operation S1 and class F windings and has a temperature limiter in three phases of the stator windings and a humidity switch.

  • This excludes the possibility of damage to the motor in the event of overloading or moisture ingress.   

  • The engine is sealed with a double mechanical seal in the oil chamber.   

  • Submersible sewage mixers are designed to work in liquids with a maximum temperature of 40 ° C, with immersion to a depth of 10m.

  • The stirrer is standard equipped with a 10 m long neoprene sheath cable.

  1. Propeller mixer for sewage produced by Metalchem-Warszawa S.A.,
  2. Engine power in kW (including one decimal place),
  3. Number of poles (indicates the rotational speed of the stirrer),
  4. Ring (no "P" means no ring).


Example of a designation: MM-226P

Propeller mixer for sewage with 2.2 kW power with a 6-pole motor and a protective ring.


A typical mixer housing is to install a vertical mast and a slider attached to the agitator that moves on the mast. It is then possible to adjust the working height of the sewage mixer and by means of a mast to set the direction of the propeller stirrer in the sewage. Below are typical installation versions. We also offer many unusual solutions, as well as often customers use our propeller mixers of our production as replacements for expensive mixers of well-known foreign producers.
