Grundfos ALPHA1 L pumps are high-efficiency circulators, designed for heating systems.

Applicable as a universal upgrade and replacement pump.

Suitable for:
  • Commercial heating
  • Commercial hot water recirculation
  • Domestic hot water recirculation
  • Domestic heating
  • Industrial heating

The ALPHA1 L 130 can be used as stand-alone or integrated circulator pump in existing as replacement or in new heating systems with either variable or constant flow rate.

The speed can be controlled by a low-voltage PWM (Pulse Width Modulation) signal.

High-efficiency ECM (Electronically Commutated Motor) pumps, such as ALPHA1 L, must not be speed controlled by an external speed controller varying or pulsing the supply voltage.

  • Three constant curves/constant speed curves.
  • Radiator heating mode.
  • Underfloor heating mode.
  • Speed control via a low-voltage PWM (Pulse Width Modulation) signal.The PWM signal is a method for generating an analogue signal using a digital source.
  • Low EEI (Energy Efficiency Index).
  • Deblocking device.
  • Maintenance-free.
  • Low noise level.
  • Very simple installation
  • Max flow – 3.885 m³/h
  • Head max – 6.376 m
  • Liquid temperature – 0 .. 95 °C
  • p max – 10 bar
