^Tsurumi Pump www.tsurumi-global.com SUBMERSIBLE AERATORS

Submersible Self-aspirating Aerators Tsurumi’s submersible aerators are used at wastewater treatment facilities to aerate and agitate industrial wastewater, livestock wastewater and other water that needs treating. More specifically, they provide the primary aeration in reactor tanks and aeration tanks at the heart of the water treatment process, and aeration and agitation in flow regulating tanks. These aerators produce tiny bubbles in the wastewater by furiously mixing in air they draw from above the wastewater’s surface, and discharge the aerated wastewater to the outside. The mixed flow of...

TRN: Submersible aerators that generate tiny bubbles to produce a high amount of dissolved oxygen and enable efficient aeration and agitation BER: Submersible jet aerators optimized for pre-aeration and prevention of bacterial spoilage PLS with Aeration Kit: Lightweight, compact resin-made submersible jet aerators for shallow water application Guide Rail Fitting System (BER-series only) The guide rail fitting system connects the pump to and from the piping easily just by lowering and hoisting the pump, allowing easy maintenance and inspection without the need to enter the sump. Selection Table...

Mixed flow of air-water profile during operation How to aerate in tank deeper than max. water depth Submersible Aerators: TRN series Aerator Operation Mixed flow of air-water is discharged in multiple directions. Tiny bubbles produce a high amount of dissolved oxygen. The rising bubbles enable efficient aeration and agitation. In combination with a blower Optional specifications (Example of installation in a 10 m-deep tank) • With stand Applicable for deep tank aeration below max. water depth. Because it draws air on its own, the aerator works with a general-purpose blower instead of a high-pressure...

Submersible Self-aspirating Aerators: TRN series Submersible Self-aspirating Jet Aerators: BER & PLS (with Aeration Kit) series 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. With the jet injector mechanism, the aspirated air mixes with water and is ejected through the diffuser, simultaneously agitating and aerating the ponded water. The mixed air-water is ejected powerfully in one direction, which...

Air Flow Rate - Water Depth Curves The air flow rates are expressed at the standard condition, i.e. temperature of 20°C, 1 atm and may vary by up to approximately 5%. Submersible aerators that generate tiny bubbles to produce a high amount of dissolved oxygen and enable efficient aeration and agitation 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...

* Max. water depth is the load limit of the motor. The load placed on the motor increase the deeper the submersible aerator is installed, therefore if the aerator is operated below the max. water depth, the overload will trip the motor protection device and stop the aerator from running continuously. *2 All weights excluding cable *3 Star-Delta available upon request Weights of guide rail fitting excluding duckfoot bend *4 Figure in ( ) shows the solids passage of the pump with a strainer.
