Grundfos Magna1 D100-100F Twin Variable Speed Circulator - 450mm - 230v

Grundfos Magna1 D100-100F (450) ERP/EUP ready twin variable speed circulator. The Grundfos Magna1 D100-100F (450) is an energy efficient variable speed circulator which is used primarily for one and two-pipe heating systems.

MAGNA1 circulator pump with easy selection of pump setting The pump is of the canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. In order to avoid problems in connection with disposal, great importance has been attached to using as few different materials as possible. A pump with no maintenance requirements and extremely low life cycle cost.

Heating systems

• Main pump

• mixing loops

• heating surfaces

• air-conditioning surfaces.

The MAGNA1 circulator pumps are designed for circulating liquids in heating systems with variable flows where it is desirable to optimise the setting of the pump duty point, thus reducing energy costs. The pumps are also suitable for domestic hot-water systems. To ensure correct operation, it is important that the sizing range of the system falls within the duty range of the pump.

Benefits

• Safe selection.

• Simple installation.

• Low energy consumption. All MAGNA1 pumps comply with the EuP requirements.

• Nine light fields for indication of pump setting. Three proportional-pressure curves, three constant-pressure curves and three fixed-speed curves are available.

• Low noise level.

• No mainteance and long life.
