Grundfos - MAGNA1 25-40N Variable Speed Circulator Pump - 180mm - 230V

Grundfos - MAGNA1 25-40N Variable Speed Circulator Pump - 180mm - 230V - MAG1C-99221223

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 mechanical shaft seal and with only two gaskets for sealing. The bearings are lubricated by the fluid medium being conveyed. 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 designed and rated 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 system 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 fixed-pressure setpoint pressure curves and three fixed-speed curves are available as an option.

• Low noise level.

• No maintenance and long life

Real-world product applications

• Boosting water pressure to multiple outlets in a building
• Maintaining stable pressure where demand varies
• Supplying water from storage tanks to distribution pipework
• Supporting general water supply and transfer systems
• Assisting with pressure control in utility installations
