Tsurumi TRN Series Submersible Self-Aspirating Aerator for Mixing Wastewater with Semi Open Impeller - Three Phase 

The TRN-series is a submersible self-aspirating aerator designed for aeration and mixing of wastewater. The liquid flow generated by Tsurumi’s special semi-open impeller causes negative pressure to form on the backside of the impeller vanes and draw in air from above the water’s surface. The aspirated air, mixed with water viciously by mechanical forces inside the impeller and guide vane, transforms into tiny bubbles. Moreover, the mixed flow of air and water is evenly discharged in multiple directions along the circumference. The compounded action of the air lift and convective currents that are generated in the process makes aeration and agitation very efficient and increases the amount of oxygen dissolved in the water.

FEATURES

• Submersible Design: No need for air blowers or additional infrastructure. The pump's direct-drive motor and submersible configuration reduce energy consumption and simplify installation.
• High Oxygen Transfer Efficiency: Built-in venturi system creates fine air bubbles for maximum oxygen dispersion—promoting efficient biological treatment and improving effluent quality.
• Agitation + Aeration in One: The TRN series achieves both water agitation and aeration, eliminating dead zones and improving total system performance.
• Clog-Resistant Impeller: Engineered for environments with high solid content, the semi-open impeller resists clogging and reduces maintenance downtime.
• Durable Construction: Crafted with wear-resistant materials such as high-chromium cast iron and stainless steel, the TRN series is built for long-term, heavy-duty operation.
