Hydroman® 150TJQ18.5-50H6B Submersible Sludge Pump
The Hydroman® 150TJQ18.5-50H6B is an electric submersible sludge pump designed for transferring sludge, sediment-laden water, and liquid mixtures containing solid particles. With a 150 mm discharge outlet, a rated capacity of 200 m³/h, and an 18.5 kW motor, it is suited to industrial and municipal applications where reliable sludge movement is essential.
This model is part of the TJQ series, which is designed for demanding solids-handling applications. Its selection should be based on the required flow rate, total head, particle size, solids concentration, and the characteristics of the pumped medium.
What Makes This Sludge Pump Suitable for Industrial Applications?
The 150 mm discharge connection supports the transfer of sludge and solids-bearing liquids through appropriately sized pipelines. Pipe diameter, conveying distance, elevation changes, and the properties of the medium should all be considered when determining the actual flow rate.
The published maximum solids passage of 56 mm is an important selection factor for applications involving coarse particles or sediment. Buyers should also evaluate particle shape, fiber content, concentration, and the possibility of foreign objects entering the pump.
The 18.5 kW motor provides the rated power for this pump configuration. Electrical supply, frequency, starting method, and continuous operating requirements should be checked before installation to ensure compatibility with the site.
The pump is installed in the liquid being transferred, making it suitable for sumps, sludge collection pits, tanks, and other installations where a submerged pumping arrangement is preferred. Correct submergence, motor protection, sealing, and discharge piping are important for dependable operation.

Typical Applications
The pump can be considered for sludge collection and transfer in wastewater treatment facilities, subject to the sludge characteristics and the required duty point.
Industrial processes may generate sludge containing suspended solids, sediment, or abrasive particles. Pump selection should account for the medium's density, viscosity, chemical properties, and wear potential.
In sediment collection pits and industrial sumps, the pump may be used to move accumulated material mixed with water. The 56 mm solids-passage rating can be useful where particle size is a major selection consideration.
For excavation pits and other construction areas, the pump may be considered when the water contains mud or sediment. Confirm that the solids concentration and required discharge head fall within the pump's operating range.
How to Select the Right Pump for Your Sludge
Choosing a sludge pump requires more than matching the motor power or outlet diameter. Before placing an order, review the following factors:
The 150TJQ18.5-50H6B has a published capacity of 200 m³/h and a head of 12 m. These figures should be evaluated together with the pump performance curve rather than treated as guaranteed simultaneous operating values under every condition.
150TJQ18.5-50H6B vs. 150TJQ18.5-50H6A
The Hydroman® TJQ series includes configurations for different pumping duties. The 150TJQ18.5-50H6B is listed as a sludge pump, while the 150TJQ18.5-50H6A is presented as a submersible sand pump.
The published specifications distinguish the two models:
| Parameter | 150TJQ18.5-50H6B | 150TJQ18.5-50H6A |
| Product positioning | Sludge pump | Sand pump |
| Discharge diameter | 150 mm | 150 mm |
| Rated capacity | 200 m³/h | 150 m³/h |
| Rated head | 12 m | 18 m |
| Motor power | 18.5 kW | 18.5 kW |
| Published solids passage | 56 mm | 28 mm |
These published values indicate different duty points and solids-passage ratings. The models should not be treated as direct substitutes solely because their motor power and discharge size are the same. Confirm the application requirements and pump curves before selecting a replacement.
Installation and Maintenance Considerations
Before commissioning, inspect the pump, power cable, discharge connection, and lifting arrangement. Verify that the electrical supply and motor protection match the manufacturer's requirements.
During operation, monitor flow, head, motor current, vibration, and unusual noise. Inspect the impeller and other wetted components periodically for wear or blockage, particularly when pumping abrasive or solids-heavy media. Follow the manufacturer's instructions for minimum submergence, seal inspection, lifting, and maintenance.
The pump should not be operated outside its approved operating conditions. If the liquid contains large fibrous materials, corrosive chemicals, or unusually concentrated solids, confirm suitability with the supplier before use.
Frequently Asked Questions
The published rated capacity is 200 m³/h. The actual flow depends on the system resistance and the selected operating point.
The published rated head is 12 m. Consult the pump performance curve to verify the head available at the required flow rate.
This model is listed with an 18.5 kW electric motor, approximately 24.8 mechanical horsepower. The required voltage and frequency should be confirmed before ordering.
The published maximum solids passage is 56 mm. Particle shape, concentration, and operating conditions can affect actual handling performance.
It may be suitable for selected sediment-bearing and abrasive mixtures, but the correct configuration depends on particle characteristics, concentration, required flow, and head. A dedicated sand-pump configuration may be more appropriate for some applications.
Provide the required flow rate, total head, pumped medium, solids size and concentration, power supply, installation conditions, and destination country. These details help the supplier recommend a suitable configuration.
