Mechanical / Hydraulic

• Design: Submersible, with motor and hydraulics integrated into one compact unit.
• Impeller:
  • Flygt Nevaclog® Impeller: Designed for smaller Flygt C-pumps with excellent flow passing properties, eliminating parts that might cause clogging.
  • Multi-vane Impellers: For bigger pumps, designed for optimum hydraulic efficiency, dynamically balanced, and machined to match the requested duty point.
  • Housing: Labyrinth seal design at the upper and lower shroud of the impeller to prevent leakage and clogging; replaceable wear rings are standard.
• Shaft: Short overhang of the shaft virtually eliminates shaft deflection, increasing seal and bearing life, reducing vibration, and ensuring quiet operation.
• Seals: Two sets of independent mechanical shaft seals for double security, designed, patented, and manufactured by Xylem.
• Seal Protection: Spin-out™ is a patented design that protects the outer seal by expelling abrasive particles from the seal chamber.
• Oil Housing: Food-grade oil-filled compartment that lubricates seals, diffuses heat from the motor and bearings, and provides additional security against liquid penetration.
• Cooling:
  • Normal applications: Cooled by the surrounding liquid.
  • Demanding applications or dry installations: Pumps can be fitted with an integrated cooling system.
• Installation Methods:
  • CS: A semi-permanent, free-standing installation; transportable version with pipe or hose connection.
  • CT: A vertically-mounted, permanent dry well or in-line installation with flange connections for suction and discharge pipe work.
  • CZ: A horizontally-mounted, permanent dry well or in-line installation with flange connections for suction and discharge pipe work.
  • CP: For semi-permanent wet well installations; the pump is installed with twin guide bars on a discharge connection.
• Applications:
  • Pumping sewage in municipal applications
  • Irrigation
  • Industrial effluent
  • Cooling water
  • Storm water
  • Process water
  • Raw water

Electrical

• Motor Type: Squirrel cage, high performance induction motor, specially designed and manufactured by Xylem for submersible use.
• Stator Windings: Trickle impregnated in resin to class H insulation, rated at 180°C (355°F).
• Cable Entry: Designed to incorporate both a seal and a strain relief function.
• Monitoring (Optional):
  • Thermal sensors embedded in the stator windings help prevent overheating.
  • Leakage sensors in the stator and oil housings.
• Approvals: All pumps are tested and approved in accordance with national and international standards (IEC 34-1 CSA). Explosion-proof versions are also available with Factory Mutual and European Norm (FM and EN) approvals.

Accessories & Control Systems

• Ancillary Equipment: Upper guide bar holder, cable holder, Flygt SUBCAB®, Flygt ENM-10 Level regulator, Flygt TOP sump (sloping floor increases turbulence to keep solids in suspension), Discharge connection, Guide bar, Flygt Flush Valve (for sump flushing).
• Monitoring and Control Systems:
  • Hardware: Pump controllers, sensors, electrical start equipment, and cables.
  • Software: Flygt AquaView supervision software provides PC-based SCADA capabilities.
  • Applications: Systems can be used to run and monitor applications in sewage treatment plants, sewage and drainage pumping, and mixing.
