Grundfos ALPHA1 15-50 N Circulating Pump

Grundfos ALPHA1 15-50 N 130 (99415696) High-Efficiency Circulator Pump

The ideal low-energy solution for domestic heating and hot water recirculation systems.

The Grundfos ALPHA1 15-50 N 130 is a premium, stainless steel circulator pump designed for exceptional energy efficiency and reliability in domestic applications. With an outstanding Energy Efficiency Index (EEI), this pump significantly reduces power consumption (down to as low as 4W), helping you save on energy bills. The stainless steel 'N' variant makes it perfectly suited for the recirculation of domestic hot water, ensuring corrosion resistance and a long service life.

Key Features

High Efficiency: Achieves one of the highest energy efficiency ratings (EEI 0.20), thanks to permanent magnet motor technology.

Stainless Steel Housing (N-Version): Ideal for use in domestic hot water (DHW) systems to prevent corrosion.

One-Button Operation: Simple, intuitive controls to easily switch between modes.

Variable Speed Control: Features three control modes (Proportional Pressure, Constant Pressure, and Constant Curve) each with multiple settings, allowing the pump to match system demands and reduce noise.

Compact Design: The pump head with an integrated control box fits easily into most common installations.

Maintenance-Free: Utilises a canned-rotor design and robust components for low noise and long-term, reliable operation.

Easy Installation: Includes an ALPHA Plug for quick electrical connection and insulating shells to minimise heat loss.

Display: Shows the actual power consumption in Watts and features LEDs for operating status.
