65TJQ3-50H4B Submersible Dredge Agitator Pump Description
Hydroman® 65TJQ3-50H4B (65mm, 25m3/h@12m) is often applied on the dredger, ship or boat, the electrical motor and pump mounted on the same shaft with equipped pump bottom agitator. Hydroman® this submersible dredge agitator pump designed and manufactured is based on fluid mechanics principles.
For applications involving heavy, compacted, or deeply settled sediment, additional agitation devices such as side agitators or jet rings can be added to enhance sediment loosening and improve overall dredging efficiency.

Design Features for Hydroman® 65 TJQ Submersible Slurry Pump
High-Efficiency Centrifugal Impeller Design: The optimized impeller geometry provides strong centrifugal force for efficient slurry transportation. The large flow passage design allows the pump to handle high concentrations of solids while minimizing the risk of blockage.
Double Mechanical Seal Protection: The pump adopts a double mechanical seal system to provide reliable separation between the motor chamber and the pumped slurry. This prevents slurry leakage into the motor and significantly improves durability during continuous heavy-duty operation.
Excellent Solids-Passing Capability: The specially designed suction inlet and hydraulic passage enable the pump to handle slurry containing sand, gravel, mineral particles, and other abrasive solids. The strong solids-handling capability makes it ideal for mining, dredging, construction, and industrial applications.
Compact Structure and Flexible Installation: The integrated pump-and-motor design reduces installation space requirements and allows quick deployment without complicated foundation structures. The pump can be easily installed in temporary or remote locations where conventional slurry pumps are difficult to operate.
Typical Materials Handled by TJQ Submersible Pumps
The fully submerged design makes Hydroman® TJQ pump suitable for underwater construction, marine sediment removal, barge unloading, caisson and bulkhead clean-out, and other offshore operations where conventional surface-mounted pumps may be difficult to install.

Hydroman® 65TJQ3-50H4A is particularly suitable for applications requiring direct submerged pumping, reliable solids handling, and efficient transportation of abrasive slurry in demanding working environments.
