Submersible slurry pump with agitator
An electric or hydraulic submersible with a stirring agitator below the impeller, dropped straight into a settlement pond, sump or tank to lift settled solids. No suction line to block.
Features
- The agitator re-suspends settled solids so the pump moves sludge rather than the clear water above it.
- Because the pump is in the liquid, there is no suction line to block — the commonest failure mode of a surface slurry pump.
- Agitation raises solids concentration at the intake, which raises power draw and wear rate, so the duty has to be sized for the agitated condition.
- Wear parts are high-chrome or rubber-lined, and on abrasive fines they are consumed in hundreds of hours rather than thousands.
- Hydraulic versions tolerate running dry and suit ponds whose level swings; electric versions need their minimum submergence respected.
- Lifting arrangements matter — these units are heavy and are retrieved for every wear-part change.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Maximum flow | 30 - 200 | m³/h | At the agitated solids concentration, not on clean water. |
| Maximum total head | 15 - 45 | m | Derated for solids. |
| Solids concentration by weight | up to 60 | % | Agitation raises it; the duty must allow for that. |
| Agitator type | mechanical / jet ring | Decides how well settled solids are re-suspended. | |
| Wear part material | high-chrome / rubber | Sets the consumable cost per hour. |
