ITT Water & Wastewater AB
Submersible motors which meet the highest demands: ITT develops high-quality submersible pumps and agitators for the efficient mixing and clog-free pumping of substrates
Only efficient mixing of the substrate will guarantee perfect mixing results. This is achieved by creating a strong, highly efficient flow in the entire pit. The strength of the flow is dependent on the thrust. The costs of the power consumption required to generate this thrust are determined by hydraulic efficiency, rotational speed and propeller diameter. We recommend combining the “Banana” large blade agitator with a compact mixer from the 4600 series.
The “Flygt Banana” agitator is a submersible mixer with an extremely large propeller diameter measuring 2.5 metres. With low rotational speed (30 to 50 revolutions per minute) and a large propeller diameter, it generates more thrust per kilowatt and is more effective than compact mixers. The propeller blades are made from glass fibre reinforced polyurethane, and the agitator is guided on a square pipe. Banana agitators are installed at a fixed height.
The compact 4600 series mixers ensure thorough mixing to prevent floating layers and sedimentation, and are installed in a manner that allows their height and direction to be adjusted. These mixers are available with rated outputs of between 2.5 and 25 kilowatts and with propeller diameters of between 368 and 766 millimetres.
Chopper pumps in the F 3000 product series are well-suited to pump substrates which have a high dry substance content. The rotary cutters have hardened edges which, working in combination with the cutting plate, effortlessly chop fibrous materials. F pumps have a wide output range (with a volumetric flow rate of up to nine cubic metres per minute and a pumping head of up to 70 metres of water column). They are specifically designed for pumping liquid manure with long fibre content and fermentation residue.
