ALPHA2 L OEM circulator pump - heating, cooling, hot water

Overview

Overview

ALPHA2 is a complete range of standalone* circulators. More than 3 million ALPHA2s have rolled off our production lines since its introduction in 2007.

The ALPHA2 L variant features integrated differential-pressure control, enabling adjustment of pump performance to the actual system requirements. The installation of a GRUNDFOS ALPHA2 L pump will reduce the power consumption considerably, reduce noise from thermostatic valves and similar fittings, and improve the control of the system.

Characteristic Features

  • High Efficiency circulator for standalone applications based on a permanent-magnet motor/compact-rotor technology
  • According Ecodesign requirement January, 2013; EEI ≤ 0.23
  • Internally self-controlled circulator
  • Integrated differential-pressure control enabling adjustment of pump performance to the actual system requirements.
  • 5 Configuration Options:
    highest proportional pressure curve (default),
    lowest proportional pressure curve
    lowest constant pressure curve
    highest constant pressure curve
    constant curve speed I, II and III
  • ALPHA2 L can run on as little as 5 W

Benefits

  • Enhance System Efficiency
    Due to the ALPHA2 L, control is affected by adapting the differential pressure to the flow.
    (proportional- and constant-pressure control). Contrary to an uncontrolled pump, the proportional-pressure-controlled GRUNDFOS ALPHA2 L reduces the differential pressure as a result of falling heating demand.
  • Compact Design
    Small and easy accessible compact design with control integrated in pump
  • High reliability
    Ceramic bearing shaft.
    The ALPHA2 L comes equipped with ceramic bearing shafts for a long and trouble-free lifetime. The ceramic material is extremely durable and will not wear.
    De-blocking system.
    Electronic de-blocking that maintains the maximum starting torque up to 25 Ncm.
    Field and lab tested product quality
