Sulzer XRW Mixers
Main industries and applications
No matter the application or the size of your facility, you need a reliable, cost-effective submersible mixer that is made to work hard, day in and day out — even in the harshest conditions. Submersible mixers type ABS XRW are robust and reliable, with an average operating life of more than a decade. They are designed to handle mixing and stirring applications in sewage treatment plants, agriculture, paper and pulp mills, and other heavy industries, including in abrasive or acidic liquids.
The XRW series can:
• Equalize sewage
• Aid biological processes (aerobic, anoxic and anaerobic) • Be used in the selector (contact zone)
•Be used in the sludge buffer tank
They can also homogenize highly-concentrated sludge and slurries, including:
• Primary, secondary and digested sludge in storage and buffer tanks
• Lime and mineral slurries And are certified for use in hazardous locations:
• Certified for ATEX (Ex II 2G Ex h db IIB T4 Gb)
• FM and CSA certification is available
Submersible mixers for large tanks and open waters
The XRW 210 to 900 mixers are a compact, highly efficient mixer range. The multi-blade propellers with two or three blades are designed to achieve high thrust and therefore a high flow capacity. This optimal flow pattern ensures that our XRW mixers handle a wide range of mixing and stirring applications. For an optimized lifecycle cost, each mixer type is equipped with the most suitable motor speed concept; asynchronous or asynchronous with a gearbox.
