Product Description
Energy-saving TSR submersible agitators
Wide range of applications
Applications are above all in municipal and industrial waste water treatment, biogas generation, industrial process technology and agriculture. In addition to avoiding deposits and floating layers, the devices can also be used for a wide range of agitating and mixing tasks.
Harshest ambient conditions
For use in potentially explosive areas, submersible motor agitators in the TSR series are available in the “pressure-tight encapsulation” explosion protection category II 2G Ex d ib IIB T3 according to ATEX. The maximum coolant/medium temperature is 60 °C.
Innovative propeller geometry
A decisive feature for comparing the efficiency of agitators / mixers is what is referred to as the first performance number as a quotient of the generated thrust force and the energy observed at the operating point. The propeller geometry that has undergone further development in the streisal fluid mechanics laboratory involving the use of the latest measuring technology and has been optimised in the test tank (large scale) means that enormously high thrust values are possible with a low power consumption. This means much lower operating costs!
Mechanical seal system
It has been shown in practice that reliability and durability of shaft seals are decisive criteria for trouble-free operation. In particular in media with relatively coarse or abrasive solids, long-fibre constituents and disruptive substances (such as plastic strands, films, etc.), the unique and patented seal system from streisal offers a series of advantages:
- Highly wear-resistant streisal Seal Guard mechanical seal made of silicon carbide
- Upstream labyrinth seal to prevent penetration by disruptive substances
- Submersible agitator housing with easily replaceable wearing ring
- Mechanical seals are protected by being mounted in a stainless steel holder
- Spring elements on the inside, not in contact with the medium
