Wilo-Extract FIRST SE 303 EM/A automatic rainwater pump. Hmax=37.1 m. 0,75 kW motor. Discharge connection G 1 inch
The Extract FIRST SE 303 EM/A (No. 6093857) is a fully submersible, multi-stage and self-priming submersible pump, equipped with a side inlet port for connecting a floating intake (SE). The unit is designed for submersible installation above the bottom of a tank or cistern, allowing the pumping of clean water from tanks, cisterns or wells with a submersion depth of up to 5 m
The self-cooling motor, through which the medium flows, allows the pump to be set up also dry, outside the tank or cistern. All parts in contact with the medium are corrosion-resistant, guaranteeing long-lasting and reliable operation
The pump is available in a 1-phase AC version, with a 10-meter power cable equipped with a plug with a protective contact. The suction hose and float filter, necessary for floating intake, are available as accessories
