3. General description
The GRUNDFOS MAGNA Series 2000 is a circulator
pump with integrated differential pressure control
enabling adjustment of pump performance to the
actual system requirements. In many systems, this
will reduce the power consumption considerably,
reduce noise from thermostatic valves and similar
fittings, and improve the control of the system.
The desired head can be set on the pump control
panel.
