2. General description
8
The GRUNDFOS MAGNA Series 2000 is a complete
9
range of circulator pumps with integrated differential
10
pressure control enabling adjustment of pump
11
performance to the actual system requirements.
12
In many systems, this will reduce the power
12
consumption considerably, reduce noise from
12
thermostatic valves and similar fittings, and improve
12
the control of the system.

13
The desired head can be set on the pump control
13
panel.

3. Applications
14
The GRUNDFOS MAGNA is designed for circulating
14
liquids in heating systems. The pump can also be
14
used in domestic hot-water systems.
15
The pump range is primarily used in
16
17
•
systems with a variable flow.
18
The pump range can also be used in
19
•
systems with a constant flow where it is
20
desirable to optimize the setting of the pump duty
21
point,
22
•
systems with variable supply-pipe temperature.
23
GRUNDFOS MAGNA pumps can be used in snow-
24
melting applications. To avoid condensation in the
24
control box, the pump should not be installed on the
return side.
3.1 Pumped liquids
Thin, clean, non-aggressive and non-explosive liquids,
not containing solid particles, fibers or mineral oil.
In heating systems, the water should meet the
requirements of accepted standards on water quality
in heating systems.
In domestic hot-water systems, it is advisable to
use GRUNDFOS MAGNA pumps only for water with
a degree of hardness lower than approx. 17 grains/
gallon (14 °dH).
WARNING!
The pump must not be used for the
transfer of inflammable liquids such as
diesel oil, petrol or similar liquids.
