Grundfos EF — Effluent Pumps for Private Dwellings

Grundfos EF — Grundfos EF AutoAdapt

Grundfos EF pumps are designed for pumping wastewater (excluding toilet waste) from private dwellings. They are also suitable for pumping liquid manure from farms, and for a variety of industrial applications, effluent and other liquids such as drainage and surface water with small impurities and solids handling up to 30 mm size, with a rigid or flexible discharge pipe mounted on the discharge port.
The EF pumps are designed for free-standing, hook-up or auto-coupling installation. The pumps are fitted with an integrated three-legged stand.
The Grundfos EF pumps are fitted with an open single-vane impeller with excellent solids-handling capabilities.
Impeller clearance can be adjusted by tightening or loosening the adjustment screws at the bottom of the suction cover. Adjustment can be carried out without dismantling the pump.
The adaptive intelligence built into the AUTOADAPT versions minimises risk factors and reduces costs for installation, commissioning and maintenance
