Tsurumi 150TRN440 Submersible Self-Aspirating Aerator – 150TRN440

The Tsurumi 150TRN440 is a high-capacity submersible self-aspirating aerator engineered for large municipal and industrial wastewater treatment applications. Utilizing Tsurumi's special semi-open impeller, the aerator draws air directly from above the water surface without requiring a separate blower for standard aeration duties. The aspirated air is mixed vigorously with water into fine bubbles and discharged evenly around the aerator, providing excellent oxygen transfer and powerful mixing throughout the treatment tank. The 40 kW motor delivers reliable performance for the most demanding continuous-duty aeration applications. :contentReference[oaicite:0]{index=0}

Built for long-term reliability, the TRN series incorporates Tsurumi's exclusive Oil Lifter, dual silicon carbide mechanical seals, and an anti-wicking cable entry system to minimize maintenance and extend service life. The 150TRN440 is suitable for installations up to 6 metres deep and can be used with an optional stand or draft tube for deeper tank applications. :contentReference[oaicite:1]{index=1}
