Product Water

Performance ranges at 2 Poles / 60 Hz are provided in graphical format in the official PDF, showing relationships between flow rate (Q in l/s, m³/h, l/min, Imp.g.p.m., US.g.p.m.) and head (H in m, ft).

Specific operating data tables are available for various pump types (e.g., E6P35, E6P45), detailing head (m) at different capacities (l/s, l/min, m³/h) for specific motor powers (kW, HP). For example, an E6P35/2B+MAC65A pump with 4 kW (5.5 HP) motor and a 3" Gas check valve can achieve a head of 35.5 m at 0 l/s and 10.5 m at 14 l/s. NPSH values are also tabulated.

Overall Dimensions and Weights

Overall dimensions (A, B, C, D, E, G, F in mm) and weights (kg) are tabulated for specific pump models (e.g., E6P35, E6P45 series). For example, an E6P35/2B+MAC65A has a maximum diameter of 150 mm and weighs 59.5 kg.
