Submersible Mixers

Submersible Mixers
  • Compact, robust direct-drive motor
  • Active Seal™ for zero leakage
  • Non-clogging, fibre-handling hydraulics
  • Low-cost installation


Our compact mixer range compact mixer components have not only been engineered for reliable operation and efficient mixing, but to reduce energy costs as well.

The plug-in seal features the Active Seal system for zero leakage into the stator housing. Laser-cut grooves on the inner seal faces act as a micro-pump to force any liquid present on the drive-unit back to the buffer fluid side. The seal housing with the barrier fluid helps lubricate and cool the seal, ensuring efficient heat transfer even when running dry.

Engineered to generate maximum thrust with minimal use of energy, the propeller blades, with their backswept design, allow highly fibrous material to pass through, while the wide-hub design deflects fibrous material.

It is possible to increase mixer efficiency by up to 15% in water, and even higher in viscous liquids such as sludge, with the optional jet ring, while further reducing energy consumption.

Optional installation methods.

Submersible Mixer Guide Bar Mounting

Figure (a) Guide bar mounting.
The most common installation method. The mixers is lowered or raised along a guide bar located on the tank wall.

Submersible Mixer Floor Mounting

Figure (b) Floor mounting.
Often used in shallow tanks and ponds. The mixer is fixed to a stand at the bottom.

Figure (c) Flange mounting.
The mixer is fixed to an adapter flange which in turn is mounted in the tank inspection hole (patent pending).

Submersible Mixer Flange Mounting

Figure (d) Cantilever mounting.
Small mixers can be mounted on a cantilever bar which is simply clamped or bolted onto the tank edge.

Submersible mixers are ideal for the following applications:

  • Activated sludge treatment such as conventional ASP or sequencing batch reactor
  • Sludge holding tanks
  • Equalization tanks
  • Pump station mixing
  • Grit chamber mixing
  • Chlorination basins
  • Paper pulp chests
  • Quenching tanks
