Sulzer submersible sewage pump XFP PE7
Sulzer Submersible sewage pump type XFP PE7 is designed for municipal
and industrial wastewater equipped with Premium Efficiency
IE3-level motor. Suitable for clean water and wastewater, sewage
with fibrous material and high contain of rags, solids and sludge.
Construction
- Premium Efficiency IE3 motors in accordance with IEC 60034-30.
- Tested 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.
- Insulation system: Class H.
- Thermal protection sensors in the stator which open at 140 °C.
- Rotor and shaft dynamically balanced.
- Upper and lower bearings lubricated-for-life, maintenance-free.
- Insulated upper bearing for VFD operation.
- Triple shaft sealing.
- Upper mechanical seal from SiC/SiC and lower mechanical seal from SiC/SiC, independent of the direction of rotation.
- Inspection chamber with sensor for moisture protection to indicate water leakage through mechanical seal.
- Blockage-free open cooling system. Cooled by the medium.
- Impeller types: 2-or 3-channel closed, skew- or mixed flow impeller.
- Option: Available in ATEX explosion-proof* version in accordance with international standards e.g. ATEX II 2G Ex db IIB T4 Gb, FM see table “Motor power and pole overview”.
