Grundfos EF Series Submersible Wastewater Pumps with Single Vane Semi-Open Impeller

The Grundfos EF Series submersible wastewater pumps are engineered for efficient and reliable removal of effluent, drainage water, and surface water containing fibres, impurities, or soft solids up to 30 mm in size. Fitted with a single-vane semi-open impeller, the EF range delivers superior solids handling and dependable operation in domestic, agricultural, and light industrial settings.

Designed for installations around homes, farms, and small commercial buildings, the EF pumps offer unmatched versatility — suitable for free-standing, hook-up, or auto-coupling setups. For the simplest installation and minimal maintenance, EF AUTOADAPT models integrate motor protection, sensors, and controller directly into the pump, requiring only a power connection.
