The Grundfos ALPHA2 15-50 130 Domestic Circulating Pump is an A-labelled energy-efficient variable speed small domestic heating circulator, where 15 is a nominal diameter of suction and discharge ports (Ø15mm), 50 is maximum head height (50dm = 5.0 m), 130 is port-to-port length (130mm), designed for the circulation of water in heating systems and domestic hot-water systems, such as underfloor heating systems and one-/two-pipe systems.
The Grundfos ALPHA2 circulating pump is the latest and most innovative member of the Grundfos family of high-quality circulators. With Grundfos ALPHA2 heating pump you can stop worrying about complicated pump settings, it's flexible, reliable, and more compact than any other A-labelled circulator pump on the market today. The Grundfos ALPHA2 circulator is the ideal choice for variety of domestic circulation heating systems, having both variable speed pressure controlled operation, and standard selectable 3-speed operation. The Grundfos ALPHA2 15-50 is an 'A' Rated Energy labelled circulating pump, achieving the highest possible energy saving under the current energy labelling scheme. The reduction of power consumption has been achieved by using the latest permanent magnet motor technology. Power consumption can be reduced to as low as 5 watts by using pressure controlled operation. The variable speed modulating modes allow the pump to match its performance to the system requirements, helping to reduce noise when thermostatic valves are closing down. Grundfos ALPHA2 15-50 130 automatically controls the differential pressure by adjusting the pump performance to the actual heating demand, without the use of external components - simply install the pump and leave it on the factory setting, AUTOADAPT, ALPHA2 will automatically analyse the heating system, find the optimum setting and continue to adjust its operation to changes in demand.
The Grundfos ALPHA2 Domestic Circulating Pump has the following features and benefits:
Compact design - The innovative design makes the Grundfos ALPHA2 the most compact Grundfos circulator available. With the electronics integrated in the pump housing, installation in very confined spaces is now possible.
Effortless installation and start-up - this Grundfos ALPHA2 heating circulator is easy to install a new or replacement pump. Thanks to the AUTOADAPT function (factory setting), the pump can, in most cases, be started without making any settings. AUTOADAPT automatically adjusts the pump performance to the demand, i.e. the size of the system and the heating demand. The performance is adjusted gradually over time. AUTOADAPT can be used in 80 % of all heating systems.
A-label - The frequency converter, permanent-magnet technology, and compact stator place Grundfos ALPHA2 highest on the energy label scheme. ALPHA2 will use up to 80% less electrical energy than D-labelled circulators.
ALPHA plug - The much appreciated and very popular ALPHA plug is the only plug in the market that offers extremely simple cable connection.
High degree of comfort - Minimum noise from valves, etc.
One-touch operation - Intuitive one-touch operation enables simple setting.
Plug and Pump - Suitable for installation in existing systems. No need to open terminal box.
LED display showing actual power consumption (Phase 1) in Watts.
Safety - Built-in electrical and thermal protection of the pump.
User-friendly front-mounted control panel.
Automatic Night SetBack (selectable) - Once Automatic Night SetBack has been activated, the Grundfos Alpha2 pump automatically changes between normal duty and night setback. Changeover is dependent on the flowpipe temperature measured by the integr
