Mega N / H

Heavy-duty electric submersible three-phase drainage pumps (IP68) for mine dewatering and large drainage duties, the largest pumps of the Grindex drainage range. Mega N (normal head, DN 150 discharge) reaches about 155 l/s (550 m³/h); Mega H (high head, DN 100 discharge) reaches heads of about 200 m; the range covers capacities from 50 to 550 m³/h and heads up to 205 m. Rated power 90 kW at 50 Hz and 104 to 105 kW at 60 Hz, solids passage 10 mm, liquid temperature up to 40 °C, pH 6 to 13, maximum submersion 75 m. A patented air valve and electronic protection allow unlimited dry running. Weight 900 kg (N) and 985 kg (H).
