Technical data

Operating range: from 0,5 a 3,6 m3/h with pressure head of up to 6 m.
Liquid temperature range: from -10 degrees C to +85 degrees C for sanitary use from -10 degrees C to +110 degrees C for others use. To avoid the formation of limescale avoid exceeding 65 degrees C and install an anti-scale system when water hardness exceeds 15 degrees f.
Pumped fluid: clean, free of solid contaminants and mineral oils, non-viscous, chemically neutral, close to the properties of water (max glycol 30%).
Max. working pressure: 10 bar (1000 kPa)
Installation with horizontal motor shaft.
