Product description

The new generation of Grundfos ALPHA GO circulation pumps

Discover the latest range of Grundfos circulation pumps, offering modern technology, easy installation and economical operation. Three new versions are gradually replacing the original ALPHA3, ALPHA2 and ALPHA1 L models – and bringing even more benefits.

ALPHA2 GO – a smart pump of the new generation
Connected to the new Grundfos GO mobile app, it offers intuitive and clear settings that anyone can use. The new unique "setup wizard" feature allows you to customize the pump to the exact parameters of your heating system. A great solution for quick replacement of older electronic pumps.

ALPHA1 GO – ideal for replacing older models
Designed for easy replacement of old non-electronic pumps. Easy to install and highly energy efficient. A great solution for modernizing existing heating systems.

ALPHA1 – the economical choice
A basic model with simple controls and reliable performance. The ideal choice if you are looking for an economical solution without unnecessary extra features.

 

The ALPHA GO series of circulation pumps is designed for installation in heating systems in single-family homes. They can be installed as stand-alone or integrated circulation pumps, but always provide maximum comfort and energy savings.

They enable quick and easy replacement of existing pumps, both old and new. At the same time, they simplify commissioning and give you peace of mind that the entire system is working efficiently thanks to the connection to the professional setup guide in the Grundfos GO app.

ALPHA1 GO is a high-quality circulation pump with features that ensure the best performance. The pump is suitable for replacing integrated UPS circulation pumps and stand-alone circulation pumps.

New and improved features such as:

  • Replacement of older stand-alone and integrated pumps
  • Automatic air venting
  • Dry-running protection
  • Robust start / reinforced starting torque

One pump in two versions.

From now on, you only need two pumps in your car to replace most stand-alone circulation pumps and up to 70% of integrated circulation pumps currently found in heating systems.

With the GO REPLACE function, which is part of the Grundfos GO app, you can find a replacement for your existing circulation pump in your system in just a few steps.

Commissioning the pump from your mobile phone.

The setup guide ensures the most accurate commissioning based on the hydronic balance of your heating system.

With the setup guide in the Grundfos GO app, commissioning is faster and ensures perfect system settings for optimal comfort and lower energy consumption.

Why ALPHA GO pumps?

  • Faster & better workflow
    With two pumps in the car, you only need one visit to the customer to replace the pump without any doubts about the correct pump settings. From installation to setup, every step is shorter, simpler and more intuitive.
  • Optimal performance
    Achieve peak system efficiency with accurate commissioning that reduces the energy consumption of the system and ensures optimal operation.
  • Optimal comfort
    Ensure the perfect balance between heating and comfort thanks to the pump's features, which adapt seamlessly to any setting.
