How to use the GO Replace app for pump replacements and upgrades

Gain a step-by-step understanding of the GO Replace app and be better equipped next time you’re performing the replacement or upgrade of a pump.

The Grundfos GO Replace app is designed to assist you in finding a replacement circulator pump. Go Replace can offer a replacement option for thousands of small, medium and large circulators from many pump manufacturers, not just Grundfos. This module will focus on our universal boiler replacement pump, the ALPHA1L, and how it can be used with the Go Replace app to replace an integrated Grundfos boiler pump.

We will also highlight the key installer benefits of GO Replace and take you through a comprehensive guide, demonstrating the simplicity and the user-friendliness of the app. Once finished, you’ll find yourself much better equipped to replace an old integrated Grundfos boiler pump.
But why should an installer actually use GO Replace as a tool for assistance?

Imagine you receive a call from a homeowner: The Grundfos pump in their boiler is broken and they need your assistance right away. Instead of going through the process of ordering the original spare part from the boiler manufacturer, you can simply replace the old pump with an off-the-shelf ALPHA1 L pump from your van. That way you can save time and avoid the unnecessary hassle of ordering spare parts.

And to make it even easier to select the right ALPHA1 L model, Grundfos has developed GO Replace. This saves you from guessing which pump model fits the boiler.
So, let’s dive straight in and take you through the app.

First of all, you’ll need to download the app on your smartphone. It’s available on both the App Store and Play Store.
When using the app you must identify the product number of the old pump – an 8-digit number. You can do this by simply taking a photo of the number. Typically, you’ll be able to find the product number on the front of the pump. If, however, you can’t locate the number, you can select the ‘Help using this tool’ button to get an idea of where the number may be located. You can also choose to enter the product number manually or search by product name by choosing ‘Search all products’.

Whichever option you choose, you will be asked to confirm that the product number is correct before you move on. If you search for another manufacturer's pump that isn't Grundfos then you will have to search by product name.
Once you have entered a product, Go Replace will offer the best Grundfos replacement solution and up to two alternatives so you can always find the perfect replacement product. GO Replace even recommends whether just the pump head or the complete pump should be replaced. On rare occasions, the app won’t recognise the product number that you’ve entered – for instance if the pump is too old-- then don’t worry as you’ll be given contact details for your local Grundfos office where you can seek further support.
Once you have selected your replacement pump a replacement report is generated. The report includes all key information of the replacement. You can either print or send the report to your prefered wholesaler or homeowner by email. It’s that simple!

All your reports are accessible from the app’s front page, meaning that you can easily gain access to them again if necessary.

In just a few simple steps Go Replace will let you choose which boiler intergrated pumps an ALPHA1L can replace. And, it’s really easy to use!
