Construction

Low-speed vertical mixer with gear motor for stationary installation.

Drive unit

IE3/IE4 gear motor for continuous operation with mixer lantern and additional bearing. The available rated power of the motor is between 0.37 kW and 7.5 kW.

Motor plate

The motor plate connects the drive unit to the structure. For this purpose, the motor plate is available in three versions. If required, the motor plate can be designed according to the system-specific requirements.

Mixer shaft

Mixer shaft made of thick-walled hollow steel. The mixer shaft is connected to the gear motor by a shrink disc. The hub is mounted on the other end of the mixer shaft via two clamping sets.

Propeller

2-blade or 3-blade propeller made of solid material. The nominal diameter of the propeller is 1500, 2000 or 2500 mm. Each propeller blade is attached to the hub. The setting angle of the propeller blade is determined in the process. The direction of thrust can be directed towards the water surface of basin floor. A cover cap is fitted to the hub to protect the hub and propeller fixture from dirt and corrosion.

Scope of delivery

  • Vertical mixer with motor plate, mixer shaft and hub
  • Propeller blades packed individually, installation on-site
  • Operating and maintenance manual

Options

  • Motor version:
    • Ex-rated in accordance with FM
    • Special voltages
    • Thermal motor monitoring using bimetallic or PTC sensors
  • Design of the motor plate according to system-specific requirements
