ABS XRW 400-650

Summary

Product identification

The ABS XRW 400 and 650 are compact and versatile submersible mixers designed for a wide range of applications, including use in aggressive and abrasive liquids.

Main applications include:

• Mixing and stirring in sewage treatment plants and industrial areas:
  • Equalization of sewage
  • Biological processes (aerobic, anoxic, and anaerobic)
  • Selector (contact zone)
• Homogenization of highly concentrated sludge and slurries:
  • Primary, secondary, and digested sludge in storage and buffer tanks
  • Lime and mineral slurries

Optional certifications for hazardous locations are available, including ATEX (Ex II 2G k Ex d IIB T4), FM, and CSA.

Electrical

• Motor: Premium-efficiency (IE3-equivalent) sensorless permanent-magnet motor controlled by a variable-frequency drive (VFD).
• Motor power: 3 – 10 kW (4 – 13.4 hp for 60 Hz).
• Motor efficiency: Up to 91%.
• Thermal protection: TCS (Thermo Control System) provides a warning or automatically switches off the motor before the permissible temperature limit is exceeded.

Mechanical / Hydraulic

• Propeller diameter: 400 / 650 mm (16 / 26 in).
• Mixing flow: Up to 0.83 m³/s (up to 13,200 USgpm).
• Bearings: Large, long-lasting bearings with a calculated lifetime of more than 100,000 operating hours, lubricated for life. Features a pre-loaded upper bearing to prevent spinning and eliminate backlash.
• Shaft: Large rotor shaft designed for heavy-duty construction to minimize shaft deflection.
• Sealing system:
  • Sealed connection chamber with quick-connection block for simplified maintenance and motor safeguarding.
  • Triple seal system with dual oil chamber for enhanced motor protection.
  • Enhanced mechanical seal protection system to keep the seal clog-free and extend its life.
• Propeller: Hydraulic-optimized stainless steel propeller designed for high mixing performance and reduced maintenance through self-cleaning.
• Suspension: Abrasion-resistant galvanically insulated guide tube and suspension to reduce the risk of electrochemical corrosion.

Materials

• Motor housing: 1.4404 (AISI 316L)
• Motor shaft: 1.4401 (AISI 316)
• Propeller: 1.4571 (AISI 316)
• Fasteners: 1.4401 (AISI 316)
