A tank mixing eductor nozzle uses a pressurized motive stream to entrain surrounding liquid and create circulation inside a vessel. It is typically considered when a process needs in-tank blending without a rotating shaft or when an existing recirculation loop can provide the required motive flow.
Jeltecn configures tank mixing eductors against the actual tank geometry, liquid properties, operating level, pump duty and mixing objective. A model should not be selected from connection size alone: induced flow, effective flow field and mixing time depend on the complete hydraulic system and must be checked against performance data.
Where a tank mixing eductor can fit
- Blending compatible liquids in storage or process tanks
- Maintaining concentration uniformity during recirculation
- Reducing dead zones in tanks with fixed internal equipment
- Supporting suspension duties when particle size, settling behavior and passage size have been reviewed
- Retrofits where an external pump loop is already available
Engineering information required for selection
| Input | Why it matters |
|---|---|
| Tank dimensions and operating levels | Define volume, flow path, submergence and possible dead zones. |
| Liquid density, viscosity and temperature | Affect hydraulic performance, pressure loss and material choice. |
| Motive flow and pressure at the eductor | Determine the operating point; pump discharge pressure alone is not sufficient. |
| Mixing objective | Blending, turnover, solids suspension and temperature uniformity require different validation. |
| Solids and contamination | Drive passage-size, filtration, wear and maintenance decisions. |
| Connection and material requirements | Must match the piping system and process compatibility review. |
How Jeltecn approaches the selection
- Define the process result and the worst-case operating condition.
- Calculate tank volume and a preliminary circulation requirement.
- Determine available motive flow after piping and fitting losses.
- Select an eductor configuration from verified performance data.
- Check quantity, location, orientation and submergence against the tank layout.
- Confirm the design through commissioning observations or process-specific testing.

Request an engineered recommendation
Send the tank drawing or dimensions, minimum and maximum liquid levels, liquid properties, pump curve or measured flow and pressure, connection standard, material restrictions and the required mixing result. Jeltecn will review these inputs before recommending a configuration. Published examples or ratios from another model should not be treated as a guaranteed result for a different system.
