Grundfos EF pumps have a single-vane, semi-open impeller for 30 mm free passage, designed for pumping effluent and other liquids such as drainage and surface water with fibres and small impurities.
Where flexible effluent pumping is required
When pumping wastewater from installations in or around housing, farms and small industry, you need flexibility, ease of use and reliable operation. The EF range of submersible effluent pumps is designed for pumping drainage and surface water as well as wastewater with small impurities and for free-standing, hook-up or auto-coupling installation.
Impeller adjustment does not require dismantling the pump and AUTOADAPT versions offer plug-and-pump simplicity. Integrating a controller, sensors and motor protection in the pump, EF AUTOADAPT pumps only need to be connected to the mains supply. The pump adapts automatically to the conditions in the pit.
