Sulzer XFP Submersible Pumps
Submersible sewage pumps type ABS XFP are the best choice for ensuring efficient and reliable pumping in any wastewater pumping station. The submersible wastewater pumps, mainly installed in network pumping stations, are equipped with Premium Efficiency IE3 motors as standard and with the ContraBlock family of impellers. They are designed to process today’s wastewater mainly composed of less water due to low-flush toilets and a range of sanitary items such as wipes, fibre material, etc.
Main industries and applications
Submersible sewage pump type ABS XFP is designed for municipal and industrial wastewater equipped with Premium Efficiency (IE3 level) motor for:
• Hazardous locations– Approval for ATEX (Ex II 2G Ex h db IIB T4 Gb), FM and CSA as standard (PE1 to PE3) *– Approval for ATEX (Ex II 2G Ex h db IIB T4 Gb), FM and CSA as option (PE4 to PE7) *
• Sewage containing solids and fibrous material
• Sewage with sludge and high contain of rags
• Industrial raw water and wastewater
• Various types of industrial effluents
• Municipal combined sewage and storm water systems
• Seawater (stainless-steel version only)
Savings with Premium efficiencies
The XFP pumps benefit from high efficiency in both motor and hydraulics, resulting in substantial savings:
• Lower energy consumption
• Reduced operating costs
• Fewer maintenance costs
• Less downtime caused by breakdowns and blockages
Great savings means a healthier environment, reducing your carbon footprint and the risk of harmful overflows.
Features and benefits
1. Vast choice of impellers
• Highly reliable and efficient impeller design with single
and multi-vane models to ensure exceptional blockage
resistance, solid passage min. 75 mm / 3 in and greater
• Optimum balance of impeller vane numbers and solids
handling, based on extensive Computational Fluid Dynamics
(CFD) research and testing
• Market leading efficiency, without compromising on solid
size and rag handling
2. Adjustable bottom plate with intercepted
slotting
• Significant energy savings throughout lifetime
• Blockage free operation
• Adjustment of the bottom plate restores pump efficiency
• Maintains efficient rag handling throughout its lifetime
3. Double volute casing from DN 400
• Reduces radial forces and shaft deflection
• Maximizes the life of bearings and shaft seals, thereby
reducing lifecycle costs
4. Double mechanical seals
• Silicon carbide/silicon carbide (SiC/SiC) provides maximum
resistance from abrasives
• Seal blockage prevention reduces operational costs
• SiC/SiC is chemically resistant in wastewater and most
other industrial applications
5. Heavy-duty stainless steel shaft
• Minimizes deflection at mechanical seal to <0.05 mm /
0.002 in.
• Increased safety against fatigue fractures
6. Heavy-duty bearings
• Minimum life 50’000 h for motors up to 9 kW / 12 hp and
minimum 100’000 h for motors larger than 11 kW / 17 hp
• Electrically, insulated upper bearing as standard for PE6 and
PE7, optional for PE5, which protects against stray electrical
currents and avoids micro-cratering in the raceway of the
inner and outer rings
7. Premium Efficiency IE3 motor in accordance
with IEC 60034-30
