Submersible Wastewater Pump | SE1 9-30KW S-Tube RangePrice Guide:$10,561Get latest price

High efficiency heavy duty cast iron submersible wastewater pumps with S-tube impeller hydraulic technology.

Flat hydraulic efficiency curves to maintain highest efficiency across pump performance range

Unmatched hydraulic efficiency of up to 84 %, combined with highest motor efficiency (modified standard Grundfos (IE3) norm motor) provides highest overall pump efficiency

No compromise between high hydraulic efficiency and free passage size

Greater free passage - For applications with required high operating hours and where dry material content is up to 3 %, the S-tube impeller with spherical free passage of up to 160 mm means greatly improved solids handling particularly with non-clogging and jamming capabilities

15 m cable lengths
