Flow Booster Type ABS SB

The reliable, energy efficient low-speed submersible unit can be used in a wide range of applications in wastewater treatment plants. This is Sulzer’s standard range of low-speed mixers; economical without compromising on the reliable design.

Information

  • This slow-speed submersible unit is available with integral motors ranging from 1.4 to 4.5 kW (1.9 to 6 hp) for gentle circulation and mixing of fluids in treatment plants and industrial applications
  • The SB features propeller blades and excellent self-cleaning properties, ensuring optimum operation with low energy input especially when used for denitrification and phosphate elimination
  • The unit is connected to a concrete pedestal by an innovative coupling system which allows the unit to be raised and lowered for inspection even in filled tanks. The pedestal absorbs all dangerous vibrations, thus giving a long service life both for the machine and the installation
