2. General description

17
The GRUNDFOS MAGNA Series 2000 is a complete
17
range of circulator pumps with integrated differential
18 pressure control enabling adjustment of pump
performance to the actual system requirements.
19
In many systems, this will reduce the power
20
consumption considerably, reduce noise from
21
thermostatic valves and similar fittings, and improve
22
the control of the system.
23
The desired head can be set on the pump control
24
panel.
