Note! Product picture may differ from actual product
GRUNDFOS ALPHA Pro is a complete range of circulator pumps featuring:
• integrated differential-pressure control enabling adjustment of pump performance to the
actual system requirements,
• optional automatic night-time duty,
• a display showing the actual power consumption (P1) in Watt and
• motor based on permanent-magnet technology.
GRUNDFOS ALPHA Pro is energy-optimised and labelled A.
The A energy label indicates the energy-saving level of the pump.
The energy classification system has seven levels, i.e. from A to G. Level A is the best.
The installation of a GRUNDFOS ALPHA Pro pump will reduce the power consumption
considerably, reduce noise from thermostatic valves and similar fittings, and improve the
control of the system.
GRUNDFOS ALPHA Pro offers a host of advantages:
• Energy savings: Automatic control of the differential pressure.
• Flexibility: Suitable for installation in existing systems.
• Night-time duty: Optional automatic night-time duty.
• Comfort: Low-noise operation.
• Safety: Built-in electrical and thermal protection of the pump.
• Userfriendliness: Simple setting and operation.
