MAGNA1 circulation pumps are responsible for circulating liquids in variable flow heating systems where the pump duty point must be optimized to reduce energy costs. The system dimensions must be within the pump operating range for the pump to function properly.

Flow Q : Max. 70 m3/h
Pressure High. hm. : Max.18 m
Liquid Temperature: Between -10°C and +120°C
System Pressure : Max. 10 bars
