The GRUNDFOS MAGNA Series 2000 is a complete
18
range of circulator pumps with integrated differential
19
pressure control enabling adjustment of pump
19
performance to the actual system requirements.
20 In many systems, this will reduce the power
20 consumption considerably, reduce noise from
20 thermostatic valves and similar fittings, and improve
22 the control of the system.
