Series XFP CB2

Sulzer submersible sewage pump XFP CB2

Submersible sewage pump type ABS XFP CB Plus is designed for municipal and industrial wastewater equipped with Premium  Efficiency IE3-level motor. Suitable for clean water and wastewater, sewage with sludge and highrag content, solids and fibrous mate-rial.

Construction

  • Premium Efficiency IE3 motors in accordance with NEMA and IEC 60034-30. Testing in accordance with IEC60034-2-1.
  • Premium Efficiency motors designed for VFD operation in accordance with IEC/TS 60034-25 A (Upeak< 1300 V).
  • The water-tight fully flood-proof motor and the pump section form a compact and robust unit, easy to clean and easy to service.
  • Water pressure sealed connection chamber, with two stage cable entry, protected against excessive cable tension and bending.
  • Bimetallic thermal sensors in the stator which open at 140 °C (284 °F).
  • Rotor and shaft dynamically balanced, upper and lower bearings lubricated-for-life, maintenance-free.
  • Insulated upper bearing for VFD operation standard for PE6 and optional for PE5.
  • Triple shaft sealing.
  • Upper and lower sealing by means of a silicon carbide/silicon carbide mechanical seal, independent of the direction of rotation.
  • Inspection chamber with sensor for moisture protection to indicate water leakage through mechanical seal.
  • Option: Blockage- and maintenance-free internal closed looped cooling system. Cooling medium: Glycol - water mixture (standard for PE6 range).
  • Hydraulic parts with 2-channel Contrablock Plus impeller.
  • These pumps are available as standard (PE4 - PE6) and explosion-proof construction in accordance with international standards such as NEC 500 Class I, Division 1, Groups C and hazardous (classifield) locations.
