Submersible Mixer II
The second mixer build in the range, for tanks where the first size cannot move the whole volume.
Overview
What This Pump Does
This is the second submersible mixer build. Like the first, it is a mechanical device used to mix sludge tanks and other liquid volumes in sewage treatment, and it adds no air to the contents.
It is specified where tank volume, depth or solids content need more thrust than the smaller build provides, or where two units are used to set up a flow pattern in a long tank.
- Mechanical mixing device for submerged installation
- Larger build for higher volume or solids
- No aeration, mixing only
- Guide rail or bracket mounting
Key Benefits
When The Larger Build Is The Right Choice
More Thrust Per Unit
Larger tanks and heavier solids need more movement than a small mixer can deliver.
Fewer Units Per Tank
One correctly sized mixer is usually simpler to install and maintain than two undersized ones.
No Aeration
Mixing only, so anoxic and balancing stages stay as the process design intends.
Same Installation Logic
Guide rails, brackets and lifting arrangements follow the same approach as the smaller build.
Application Scenarios
Where It Is Installed
Large Sludge Holding Tanks
Keeping a big volume homogeneous before dewatering or transfer.
Deep Anoxic Basins
Maintaining movement where depth makes a small mixer ineffective.
Long Rectangular Tanks
Two units arranged to create a circulating flow along the tank.
Who It Is For
- Treatment works with large holding tanks
- Industrial plants with high solids effluent
- Biogas operators storing digestate
- Designers laying out flow patterns in long tanks
Problems It Solves
The tank is too big for one small mixer
Correct thrust for the volume is what prevents settled corners, not simply adding machines.
Heavy solids settle quickly
Higher thrust keeps denser material in suspension between transfers.
Flow patterns break down in long tanks
Sizing and positioning together create a circulation that reaches the whole length.

Compared With Other Options
| Submersible mixer | The same function in a smaller build. Selection follows tank volume, depth and solids. |
|---|---|
| Submersible aerator | An aerator adds air. If the process stage must stay anoxic, use a mixer. |
Use Guide
Laying Out Mixers In A Large Tank
Sketch The Tank
Length, width, depth and the position of inlets and outlets determine the flow pattern.
Decide Unit Count
One correctly sized unit beats two undersized ones in most rectangular tanks.
Set Orientation
Angle the units so the circulation sweeps the floor rather than the surface.
Review After Commissioning
Check for settled areas after a few weeks and adjust orientation before adding machines.
Answers
Submersible Mixer II FAQ
How is this different from the first mixer?
It is the larger build in the same range, for tanks where more thrust is needed to move the whole volume.
Does it aerate?
No. It is a mixer, so it moves the contents without adding air.
Can two units be used in one tank?
Yes, and in long rectangular tanks that is often how a circulating pattern is set up.
What information do you need to size it?
Tank dimensions, minimum operating level, solids content and the position of inlets and outlets.
Can it be lifted out for service?
Yes with guide rails and a lifting arrangement specified at the order stage.
