Immersible Aerator
The immersible build of the self priming aerator, working under water with no compressor and no air main.
Overview
What This Pump Does
The immersible aerator is the same self priming aerator principle supplied for installations where the unit sits immersed in the basin. It integrates pump, air blower and gas liquid mixer, and can be placed on the bottom of the aeration pool or fixed to a floating body.
Impeller rotation draws air through the pipe by vacuum in the stator, mixes it with water inside the impeller, and disperses the gas as bubbles of around 100 microns in diameter.
- Self priming aerator integrating pump, blower and mixer
- Star type impeller with stator and air pipe
- Bubble dispersion around 100 microns
- Submerged operation, bottom or float mounted
Key Benefits
Oxygen Transfer Without Support Infrastructure
Self Priming For Air
No compressor or blower is needed, because the impeller creates the vacuum that pulls air down the pipe.
Mixing Included
The unit keeps the medium moving while it aerates, which is what activated sludge duty requires.
Placement Flexibility
Bottom mounted or float mounted depending on basin depth and level variation.
Effective Oxygen Transfer
Around 100 micron bubbles give the surface area that makes transfer efficient.
Application Scenarios
Where It Is Installed
Aeration Tanks
Continuous oxygen supply and mixing in activated sludge basins.
Stabilisation Duty
Sludge stability treatment stages where mixing and oxygen are both required.
Batch And Balancing Tanks
Tanks that need intermittent aeration and constant movement of the contents.
Who It Is For
- Treatment works upgrading aeration capacity
- Industrial effluent plants
- Consultants specifying basin equipment
- Operators replacing surface aerators
Problems It Solves
Surface aerators freeze and spray
A submerged unit works below the surface, which avoids spray, aerosols and cold weather icing.
Air mains are expensive to install
Drawing air down a pipe from the unit removes the buried air main from the scope.
Uneven basin mixing
The unit moves the medium as well as aerating, so solids stay in suspension.

|---|---|
| Submersible mixer | A mixer only moves the contents. Choose it for anoxic zones where air would work against the process. |
Use Guide
Running An Immersible Aerator
Confirm Submergence
Check the unit stays properly submerged at minimum operating level.
Keep The Air Intake Clear
Inspect the intake for foam and debris as part of routine checks.
Fit Lifting Gear
Guide rails or a lifting arrangement turn a service job into a routine task.
Track Dissolved Oxygen
Monitor DO so falling transfer is detected before the process reacts.
Answers
Immersible Aerator FAQ
What is the difference from the SKCB aerator?
Both are self priming aerators on the same principle. The build is chosen on basin depth, mounting arrangement and duty.
Can it be float mounted?
Yes. It can be placed on the bottom of the aeration pool or fixed to a floating body.
Does it mix as well as aerate?
Yes, the main application is supplying oxygen and mixing the medium transported.
What bubble size does it produce?
Around 100 microns in diameter.
Which stages is it used in?
Pre-gas supply, activated sludge treatment, sludge stabilisation, gas floats, neutralisation, ozone treatment and oxidation ponds.
