MAGNA1 circulating pumps are designed for circulating liquids in heating systems with variable flow rates where it is convenient to optimize the setting of the pump's working point, thus reducing energy costs. To ensure proper operation, it is important that the sizing range of the system is within the working range of the pump. Features: Proportional pressure control. Constant pressure control. Work at constant curve / constant speed. The motor does not require external protection. Single-head pumps for heating systems include insulating casing. Wide temperature range and independence between the temperature of the liquid and the ambient temperature.
MAGNA1 25-80 The new MAGNA1 is the easiest option for a job well done. It is the perfect choice when replacing old circulators and, thanks to its EuP 2015 compliance, significant electricity savings are achieved. It is the ideal solution for basic performance needs in applications where a basic monitoring and control system is required.
- Supervision by fault relay, which provides great peace of mind.
- Digital start/stop input available for remote pump control.
- Continuous operation and reduced downtime with wireless dual pump function (available on dual pumps).
- High efficiency that guarantees substantial electricity savings.
- Easy setup and operation through simple interface.
- Maintenance free due to canned rotor type design.
MAGNA1 is the simplest and most efficient choice for most applications including
Heating:
- Main pump
- Mixing loops
- Heating surfaces
Refrigeration:
- Air conditioning surfaces
- Geothermal pumping systems
- Small chiller applications
