Tsurumi 50TRN43.7 Submersible Self-Aspirating Aerator – 50TRN43.7

The Tsurumi 50TRN43.7 is a submersible self-aspirating aerator designed for efficient aeration and mixing in sewage and 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 air and water are vigorously mixed into fine bubbles and discharged evenly around the unit, providing high oxygen transfer efficiency and powerful tank agitation.

Engineered for continuous-duty operation, the TRN series features Tsurumi's exclusive Oil Lifter, dual silicon carbide mechanical seals, and an anti-wicking cable entry system to deliver reliable performance, extended equipment life, and reduced maintenance in demanding wastewater treatment environments.
