SMALL AGITATOR TANKS AND PONDS
The fast-running submersible agitators of the TRV type are suitable above all for swirling up deposits and solids, for example in pumping stations, equalisation or retention tanks as well as for industrial mixing of all kinds of substances in relatively small agitating tanks.
EXTREME OPERATING CONDITIONS
The universally applicable submersible motor agitator has a high-alloyed stainless steel housing and opens up entirely new applications – even for adhesive, highly aggressive and abrasive media. Seal elastomers are available either as fluorinated rubber (Viton) or as perfluorelastomers (Kalrez, Prafluor).
STURDY STAINLESS STEEL HOUSING
The robust small submersible motor agitator has a housing made of high-alloyed stainless steel which can be used even for difficult agitating and mixing tasks.
MAXIMUM PERFORMANCE IN THE SMALLEST SPACE
With its compact design, the submersible agitator is also suitable for tight installation openings for subsequent installation.
FLEXIBLE ADAPTATION TO THE MATERIAL BEING MIXED
When operated with a frequency inverter, variable speeds and propeller diameters allow for flexible adaptation to the medium.
