Circulation pumps class A - Grundfos Alpha 2 and Alpha 2L

Circulation pumps class A - Grundfos Alpha 2 and Alpha 2L

Price:€286.84
Weight: 2.200 Kgs

Purpose: Circulating pumps new generation of floor heating, radiant heating , pipe and two-pipe systems.

Application: Systems with constant or variable flows where it is desirable to optimise the setting of the pump duty point. Systems with variable flow temperature in the pipes.

Construction: GRUNDFOS ALPHA2/2L combines engine rotor with permanent magnets and differential-pressure control, allowing continuous adjustment of the pump according to the actual needs of the system.

Control Panel: GRUNDFOS ALPHA2/2L has an easy to use control panel, front-mounted pump. The control panel can be rotated in steps of 90 degrees. Additional equipment (ALPHA2): Thanks to the AUTOADAPT (factory setting), the pump can, in most cases, be released without any settings. A brief description of the panel (ALPHA2): Display showing the actual power consumption of the pump in W. Eight light fields indicating the pump setting. Light field indicating the status of an "automatic night work". (ALPHA2L): LED "POWER ON". Seven LEDs for pump settings. Button to select the setting of the pump.

Energy class: Low power consumption compared to conventional circulator pumps. GRUNDFOS ALPHA2/2L is energy class A.

Features and Benefits: Minimum noise from valves, etc. Mode "Night work" (ALPHA2): If the water temperature drops by more than 10-15° C within 2 hours. Changeover to "normal operation" is performed when registering an increase of temperature by 10 °C. The pump must be installed in the flow pipe.
