Features and benefits
Features
• Proportional pressure control.
• Constant pressure control.
• Constant curve/constant speed duty.
• No external motor protection required.
• Insulating shells supplied with single-head pumps
for heating systems.
• Wide temperature range where the liquid
temperature and the ambient temperature are
independent of each other.
Benefits
• Simple installation.
• Low energy consumption.
• Eight light fields for indication of pump setting.
• Low noise level.
• No maintenance and long life.
Applications
Heating systems
• Main pump
• Mixing loops
• Heating surfaces
• Air conditioning surfaces.
The MAGNA1 circulator pumps are designed for
circulating liquids in systems with variable flows where
it is desirable to optimize the setting of the pump duty
point, thus reducing energy costs.
To ensure correct operation, it is important that the
sizing range of the system falls within the duty range of
the pump.
