Hydroman^® 200TJQ22-50H6A Submersible Solids Handling Pump

An agitator that goes after the problem at the source

In most sumps and settling pits, solids do not stay in suspension. Sand, silt and sludge drop to the floor, and a standard pump sitting above them mostly pumps clear water while the sediment layer keeps growing. The bottom-mounted agitator on the 200TJQ22-50H6A churns that layer back into the liquid around the inlet, so the pump has something worth lifting. If your job is sediment removal rather than simple dewatering, this is the feature that matters most.

A protective screen for the debris you do not want

A screen on the bottom inlet keeps oversized items such as rocks, timber offcuts and rubbish from being pulled into the impeller. Think of it as a gatekeeper, not a filter. It is sized to the solids the pump can pass, and it will not make the pump immune to clogging with stringy or fibrous material. Tell us what is actually in your pit and we will help you choose a suitable opening.

High flow at low head

The 300 m³/h at 10 m duty point puts this squarely in the high-volume, low-lift category. For context, that flow rate moves roughly 83 litres every second. In a 200 mm discharge line, it works out to a velocity of about 2.65 m/s, which sits comfortably inside the 1.5 to 3 m/s range commonly used for pumping sand-bearing slurries. Go much slower and sand begins to settle in the pipe. Go much faster and you accelerate pipe and bend wear.

Cast iron construction for rough service

This is a cast iron submersible pump, chosen for its rigidity and abrasion resistance in demanding duty. Cast iron is a long-established material for solids transfer pumps and works well in many sand, silt and general industrial effluent applications. If your liquid is strongly acidic, chloride-rich or highly abrasive, discuss material options with our team before ordering.

A submersible motor and pump in one package

Because the motor sits below the water line with the pump, there is no long vertical shaft, no dry-pit space to build and no priming to worry about. The surrounding liquid also helps carry heat away from the motor. That is a big advantage over a vertical pump with a dry-mounted motor if your site is a deep, narrow pit or a flooded excavation.

Here are the numbers you will need for a first-pass selection.

The 980 r/min rating tells you something useful about the motor. A 50 Hz motor with six poles has a synchronous speed of 1,000 r/min, and slip brings it down to the high 900s. A slower six-pole design is a common choice for pumps that handle abrasive solids, because lower impeller speeds generally mean less wear on the wet end than a 2-pole machine running near 2,900 r/min. Your voltage, frequency and winding details should be confirmed with us when you place an order, so the pump matches your site supply.

A Quick Reality Check on Power and Slurry Density

Here is a number worth knowing. Moving 300 m³/h of clean water through 10 m of head takes roughly 8.2 kW of hydraulic power (ρ × g × Q × H, with water at 1,000 kg/m³). Slurry is heavier. If your mixture has a specific gravity of 1.3, that hydraulic requirement climbs to roughly 10.6 kW before pump and motor losses are counted, and the agitator also draws power. The 22 kW motor gives you the headroom to deal with denser mixtures, start-up loads and the extra work of stirring settled material, which is exactly where lightly powered dewatering pumps struggle.

As a practical guide, here is how the rated duty compares at different slurry densities, based on the physics above.

These figures exclude hydraulic and motor efficiency losses and agitator load. Actual flow and head will also shift with slurry density, solids size and your system curve, so treat the table as a sizing guide rather than a performance guarantee.
