Hydroman® 200TBS415 Submersible Agitator Pump
If you've ever watched a "normal" submersible pump choke on settled sand within a week of startup, you already know why a submersible agitator pump exists in the first place. You need something down in the sump or pit that doesn't just move water – it moves what's sitting on the bottom of it. The Hydroman 200TBS415 is built for exactly that job: a 15kW electric submersible agitator pump with a 200mm discharge, designed to stay productive in sand, sludge, mud, tailings and sediment that would stall a conventional unit within hours.
The 200TBS415 sits in Hydroman's mid-to-large frame of submersible slurry pump with agitator units, built around a 15kW three-phase submersible motor and a mechanical agitator mounted directly beneath the impeller. It's not a modified sewage pump with a blade bolted on – the agitator, shaft, and impeller are engineered as one system so the pump can actually keep pace with settled solids instead of just skimming the liquid off the top.
You'll typically see this frame size specified where sump depth, solids load, or continuous-duty requirements rule out a standard submersible: mine dewatering sumps, dredging support ponds, foundation pits, and industrial settling tanks where the bottom sediment is the whole problem, not a side effect.
Key Features
Every submersible pump with agitator lives or dies by how well the agitator and impeller are timed together. On the 200TBS415, the agitator blades rotate at the pump's base to break up settled and compacted material before it ever reaches the suction eye, keeping particles in suspension instead of letting the sump re-stratify between duty cycles. That's the difference between a pump that "pumps water and leaves the solids behind" and one that actually clears the pit.
The three-phase motor is insulated to Class H and runs at a comparatively low operating speed for its class – a design choice you'll find across most reputable submersible agitator lines, since lower RPM directly reduces wear rate on the wetted parts and extends component life between rebuilds. It's rated for continuous submerged operation, not intermittent duty, so you're not babysitting run times.
This is where the 200TBS415 earns its "slurry pump" label rather than just "submersible pump." Depending on particle size and specific gravity, agitator-equipped submersible pumps in this class are commonly specified against solids concentrations from roughly 25% by weight for typical mining sump duty up to 60–70% for thickened tailings, at specific gravities up to around 1.6–1.7 – figures that are broadly consistent across published engineering guidance for this pump category.[1] The 200TBS415 is built to that same operating envelope.
The impeller and agitator blades are cast from high-chrome alloy, which is the standard material choice across the industry for anything that stays in continuous contact with abrasive sand, ore slurry, or mineral tailings – it simply outlasts standard cast iron by a wide margin in this service. The casing and wear plate follow the same logic, and the double mechanical seal arrangement protects the motor chamber even as the outer seal face wears down over time.
At 200mm, the discharge is sized to pass larger solid fragments without packing off, which is the whole point of a submersible trash pump with agitator style design – you want fewer callouts to clear a jammed impeller, not a smaller opening that looks efficient on paper and clogs in the field.

How the Agitator Actually Works
It helps to picture the sequence rather than think of the agitator as a separate machine bolted onto a pump:
The agitator blades, positioned just below the pump body, rotate first and loosen the compacted or settled layer of solids sitting at the bottom of the sump. As that material lifts, it mixes with the surrounding liquid into a more uniform slurry rather than staying as a solid mass on the floor. That homogenized mixture is drawn into the suction eye, where the open impeller generates the centrifugal force needed to move it – and because the mix is already fluidized, the impeller isn't fighting a plug of packed sediment. From there it's pushed out through the 200mm discharge and into your pipeline.
Compared with a standard submersible pump asked to do the same job, the practical difference shows up in uptime: sites running conventional pumps in heavy-solids sumps commonly report multiple blockages a month and periodic motor burnout from dry-running once the pump has "pumped the water and left the solids behind." Agitator-equipped units are specifically built to avoid that failure pattern by keeping the bed in suspension continuously rather than intermittently.
Where You'll Put It to Work
| Sector | Typical Duty |
| Mining | Tailings pumping, mineral slurry transfer, ore processing, underground slurry removal from mine sumps |
| Dredging & Sand Recovery | River and lake dredging, pond and marina silt removal, sand recovery – the same category of duty covered by a submersible sand pump agitator or submersible agitator sand pump setup |
| Construction | Foundation pit dewatering, excavation slurry removal, tunnel wastewater pumping |
| Industrial Wastewater & Sludge | Settling tank cleaning, thickened sludge transfer, industrial slurry handling ahead of digesters or clarifiers |
A real-world reference point worth keeping in mind: at an open-pit mine handling seasonal runoff mixed with blasting debris (slurry specific gravity 1.3–1.5, rock fragments up to roughly 50mm), sites running conventional submersible pumps have reported around two blockages per month and roughly one motor burnout annually before switching to agitator-equipped units sized to the sump volume and head – after which the "pump water, leave solids" failure mode largely disappeared. That's the kind of operating gap this pump class is built to close, and it's exactly the profile the 200TBS415 is designed against.

Why Buyers Choose the 200TBS415
Most people shopping for a submersible agitator pump for sale are replacing something that already failed, so they're less interested in a features list and more interested in whether the next pump will actually survive their site. That's the case the 200TBS415 is built to make: a heavy-duty design for high-density slurry, strong sand and sediment handling from the integrated agitator, a 15kW motor sized for continuous rather than intermittent duty, meaningfully lower clogging risk than a straight submersible, and wear components chosen to be rebuilt rather than replaced outright. It's also straightforward to install and operate as a standard vertical submersible unit, and Hydroman can adjust impeller trim, agitator configuration, and materials for your specific slurry rather than shipping a one-size-fits-all spec.
If you're weighing this against a smaller frame, it's also worth comparing directly against the 200KBS415 – a closely related model in the same size and power class.
Choosing the Right Size
Before you request a quote, it's worth working through four numbers, because getting any one of them wrong either leaves performance on the table or shortens the pump's life:
| Factor | Why It Matters |
| Solids Concentration (% by weight) | Roughly 5% is light duty, ~25% is typical mining sump duty, 60%+ is thickened tailings – this drives both de-rating and material selection |
| Particle Size & Specific Gravity | Determines impeller clearance, agitator torque, and whether a semi-open or open impeller is the right call |
| Total Dynamic Head | Static lift plus pipeline friction losses plus any required delivery pressure at the discharge point |
| Motor Power | The 200TBS415's 15kW sits mid-range in Hydroman's line – smaller sumps may only need 5.5kW, while heavier dredging duty can call for 30kW and up |
If you're not sure where your application lands, send us your sump volume, expected solids content, particle size, and required head – that's enough for our engineering team to confirm whether the 200TBS415 is correctly sized or whether a different frame in the range fits better. Pricing on a submersible agitator pump this size depends heavily on motor spec, impeller trim, and seal configuration, so treat any submersible agitator pump price you see online as a starting point, not a quote.

What is a submersible agitator pump?
It's a submersible pump that combines a mechanical agitator with the impeller so it can re-suspend settled solids before pumping them, rather than only moving the liquid sitting above the sediment bed.
What materials can the Hydroman 200TBS415 handle?
Sand, mud, sludge, tailings, sediment, and general abrasive slurry, at solids concentrations and particle sizes consistent with a heavy-duty submersible solids handling pump in this frame size.
What's the real difference between this and a standard submersible pump?
A standard submersible pump can only move what's already suspended in the liquid around it. Once solids settle and compact, it either stops moving product or runs dry and burns out the motor. The agitator solves that by continuously breaking up and re-suspending the bed.
Is the 200TBS415 suitable for pond or dredging work, not just mining?
Yes – the same agitator mechanism that handles mine tailings works for pond pumps submersible agitator pump applications like silt removal and sand recovery; the sizing conversation is really about solids concentration and particle size, not the industry label.
Can I buy a large submersible agitator pump from Hydroman, or is this the largest frame?
The 200TBS415 is a mid-to-large frame in our range. If your duty point calls for a large submersible agitator pump beyond 15kW, we carry larger motor frames – send us your sump and head data and we'll confirm the right size.
