Sulzer submersible sewage pump XFP 105J – 600X
Sulzer submersible sewage pumps, series XFP are suitable for clear and wastewater, for sewage with sludge containing solids and fibrous material.
Construction
- Energy saving premium efficiency motor in accordance with IE3 of IEC 60034-30, exceeding EFF1 of CEMEP regulation.
- 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.
- Rotor and rotor shaft dynamically balanced, upper and lower bearings lubricated-for-life, maintenance-free.
- Triple shaft sealing.
- Upper and lower sealing by means of a 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 various impeller options: 2-or 3-channel Contrablock, 2-or 3-channel closed or 3-channel skew.
- These pumps are built as standard in ATEX explosion-proof version in accordance with international standards e.g. Ex d IIB T4/ATEX II 2Gk.
