Grundfos ALPHA2 25-60 N 130 Multi-Speed Stainless Steel Hot Water Circulator – 99411287

Grundfos ALPHA2 high-efficiency circulator pumps are designed for circulating liquids in heating systems. The stainless-steel variant of the ALPHA2 is suitable for e.g. domestic hot-water systems. With an energy efficiency index (EEI) well below the ErP benchmark, it ensures substantial energy savings.

The AUTOADAPT function continuously adapts the pump performance to the actual heat demand, i.e. the size of the system and changing heat demand during the year. The AUTOADAPT feature finds the setting that provides optimal comfort with minimal energy consumption and makes the commissioning fast, safe, and easy. ALPHA2 also offers proportional-pressure, constant-pressure and constant-curve control modes.

With the automatic night setback function, the pump automatically changes between normal duty and night setback. The changeover depends on the flow-pipe temperature controlled by the heating appliance. In manual summer mode, the pump does not operate but starts automatically at low speed to avoid blocking the rotor as well as sticky valves and non-return valves.

Control modes and functions are selected using the buttons on the display. The LEDs indicate the operating status, actual power consumption in watt or actual flow rate in m³/h as well as warnings and alarms.

Furthermore, ALPHA2 is compatible with ALPHA Reader and the Grundfos GO Balance app, enabling installers to perform easy hydronic balancing of radiator- and underfloor-heating systems.

The design and chosen materials of the pump contribute to long life. The pump is self-venting through the system, which contributes to easy commissioning. The compact design, featuring a pump head with an integrated control box, fits into most common installations. Pump and motor form an integral unit without a shaft seal. The bearings are lubricated by the pumped liquid. These constructional features ensure maintenance-free operation.

The active dry-running protection feature protects the pump against dry running during startup and normal operation. In case of a blocked rotor, the pump will continuously attempt to restart with highest possible torque.

Pump housings made of cast iron are electrocoated to improve corrosion resistance. The motor is a synchronous permanent-magnet/compact-stator motor characterised by high efficiency. The pump speed is controlled by an integrated frequency converter incorporated in the control box.

Insulating shells are supplied with pumps to minimise heat loss in heating systems.

The Grundfos ALPHA2 N is an intelligently controlled,
ultra quiet, hot water circulation pump designed to circulate hot
water around the home, making it instantly available for taps in
the bathroom, kitchen or anywhere hot water is required.

• Instant hot water at the tap – As circulators provide
instant hot water at the tap (with return line), they can
save hundreds of litres per year from going down the drain
while you wait for hot water to arrive from your hot water
system

• Energy efficient – the AUTOADAPT feature “learns” the hot
water consumption pattern of the home and then varies
pump use accordingly in the future, providing superior
levels of energy efficiency compared to other circulators
that run continuously

• Hygienic, stainless steel construction throughout

• Ultra quiet operation – Very quiet operation that won’t
disturb your family

Suitable for

  • Commercial hot water recirculation
  • Domestic hot water re-circulation – Domestic building

ALPHA2 N is a circulator pump with stainless-steel pump housing for domestic hot-water systems. AUTOADAPT continuously adapts the pump to system demands for optimal comfort and low energy consumption.
