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
