The Grundfos EF pumps are designed for pumping wastewater without toilet waste from private dwellings.
These pumps are also suitable for pumping liquid manure from farms, and for a variety of industrial applications.
The EF pumps are designed for free-standing installation. The pumps are fitted with an integrated three-leg stand that keeps the suction inlet well clear of the pit bottom.
The Grundfos EF pumps are suitable for pumping effluent and other liquids with a pH value of 4 to 10. The EF pump range is able to handle liquids with solids up to 30 mm.
The Grundfos EF pumps are suitable for the following applications:
- Drainage and surface water with small impurities
- Wastewater with fibres, e.g. from laundries
- Wastewater, without discharge from toilets
- Wastewater from commercial buildings, without discharge from toilets
The EF range comprises models for single-phase or three-phase voltage supply. All types are designed for voltage tolerances of –10%/+6%. The single-phase versions require a control box with built-in operating capacitor of 30 uF.
