H Total head in m. With single-phase motor = NMM - NMDM. Maximum suction lift 1-2 m. Tolerances according to UNI EN ISO 9906:2012 Regulation (EU) No 547/2012 - The benchmark for most efficient water pumps is MEI ≥ 0,70. - The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller diameter. The trimming of the impeller will adapt the pump to a fixed...
