Heavy duty aerator makes light work of big jobs


Australian Pump Industries now offer a 40kW Tsurumi submersible aerator with an airflow rate of 528 cubic metres per hour.

Designed for wastewater and sewage applications, the big aerator can operate from depths of 6m with a maximum of up to 8 outlets.

The Tsurumi 150TRN-440-52 is a self-aspirating submersible aerator with an integrated semi open impeller.

The impeller draws air through the intake, mixes it with the liquid being aerated and discharges at a high pressure.

This leads to highly efficient aeration with a number of other significant advantages over conventional aeration means.

The air sucked down into the aerator is subject to an air water collision within the guide vanes of the machine.

Its size and capacity makes it suitable for circular tanks of up to 17m diameter and square tanks of up to 15m diameter. Those figures relate to tanks of up to 6m depths.

For larger tanks two or more aerators can be installed to provide the right results.

The 150TRN-440-52 operates with a 6” air inlet (150mm) providing a main convection diameter of 7.3m.

The motor supplied is a heavy duty 415 volt 3 phase, 40kW submersible design, wound to Star Delta. The motor is four pole, operating at 1500rpm.

The major components activating the liquid are stainless steel including the impeller and the machine is protected by Tsurumi’s normal heavy duty double silicon carbide mechanical seal, located in an oil chamber keeping all surfaces lubricated.

The machine also comes with a patented oil lifter to ensure the mechanical seals are cooled, even if the oil level is low.

Heavy duty cables pass into the motor through an “anti-wicking” cable entry that provides a water tight connection even if the cable is damaged.

Australian Pump Industries, exclusive distributors of Tsurumi pumps in Australia, believe the new aerator will be of interest to sewage station and effluent system designers throughout the country.

Tsurumi is the world’s biggest manufacturer of electro submersible pumps with a manufacturing capacity in excess of 1 million units per year at their Kyoto factory.

They are leaders in the design of sewage system equipment that includes both big non-clog style pumps and aerator systems.
