Performance Table:

Will this pump suit my job? Add up the height the water must be lifted (from the water level to the highest outlet) plus about 1m for every 10m of pipe and fittings – that is your total head. Then find your flow in the table: the pump is a good match if the head at your flow is at or just above what you need. This model works best around 12 m³/h at 19.5m. 380V and 525V motors need a three-phase supply and a suitable starter/overload; 220V motors run on normal household single-phase power. Not sure? Send us your flow, lift and pipe length and we will size it for you.
