IMPORTANT SAFETY RECALL NOTICE – CERTAIN 3" SQFLEX PUMPS

21-August-2026

Grundfos has initiated a voluntary recall of certain 3" SQFlex pump models manufactured between September 29, 2025, and May 17, 2026, with production codes 2540 through 2620. The issue was identified during a routine quality review conducted by the Grundfos Quality team. No injuries have been reported.

Grundfos has identified that, under certain conditions, the pump's motor lead cable may become damaged where it contacts the cable guard. If damage to the cable insulation occurs, exposed wiring could create a potential electric shock risk when electrical power is supplied. As a precautionary measure, Grundfos is working directly with affected customers and channel partners to identify and remedy affected products.

Products Included in This Recall

The recall applies to the following 3" SQFlex pump models with production codes 2540 through 2620:

  • 3 SQF-2
  • 3 SQF-3
  • 6 SQF-2
  • 6 SQF-3
  • 11 SQF-2

Important Safety Information

If you have a potentially affected pump that is being handled, tested, or operated above ground, do not energize, test, operate, or use the pump until you have determined whether it is affected by the recall.

Pumps already installed in a well do not need to be removed solely because of this recall. Based on Grundfos' current technical assessment, no immediate action is required for pumps already installed in a well. If the pump is removed from the well at a later date, the power supply must be disconnected before handling the pump and the recall instructions should be followed.

How to Determine if Your Pump Is Affected

To determine whether your pump is affected:

  • Locate the production code on the pump nameplate or package label.
  • Verify that the pump model is one of the affected 3" SQFlex models listed above.
  • Confirm whether the production code falls within the affected range of 2540 through 2620.

If your pump meets both criteria, it is included in the recall.

What Should You Do?

Please take the following actions immediately: 

For all installed pumps disconnect the power supply before following the below steps.

1. Identify and locate the relevant pump(s) 

Identify and locate any 3” models of SQFlex Pumps in your possession, custody, or control that were supplied by Grundfos after 28 September 2025. If you are not the end-user, please immediately identify any affected downstream customer(s), including end-user(s), installer(s), dealer(s) and/or other reseller(s).

2. Pumps not yet installed

To identify if you have any affected pump(s) please follow points 5-6 below immediately.  

3. Pumps already installed in a well

Based on Grundfos’ current technical assessment, no immediate action is required for pumps already installed in a well. Such pumps should not be pulled out of the well solely because of this letter. However, when the pump is pulled out of the well in the future, before pulling it out disconnect the power supply and follow points 4-6 below.

4. Pumps handled or used above ground

Before carrying out points 5 and 6 below, disconnect the power supply. Potentially affected pumps handled or used above ground must not be turned on again, energized, tested, operated, used for water transport, or handled in a wet or above-ground test environment, unless it has been confirmed through the steps below that the pump is not affected. 

5. Identify pump model and production code of the pump(s)  
Check the 3” SQFlex pumps’ model and production code (year/week) and confirm whether it falls within the affected models and within production code range 2540 to 2620, corresponding to pumps manufactured from 29 September 2025 to 17 May 2026, both dates included. Appendix 1 explains how to locate the model and production code on the nameplate of the pump and the package label.

Once a pump has been confirmed as affected, it must not be turned on again, energized, tested, operated, used for water transport, or handled in a wet or above-ground test environment as stated above.  
 

6.  Isolate pumps and contact Grundfos  

Once you have identified one or more pumps as affected based on Appendix 1, please stop selling and isolate all affected pumps and contact your local Grundfos representative to arrange for repair or replacement of the pump(s). Grundfos will provide the remedy free of charge. If there is an urgent operational need to continue pumping, please contact Grundfos before taking any further action. 

7.  Notify downstream customers as soon as possible  

If you are a distributor, channel partner, or any other type of customer that has resold the unit, please promptly ensure that any affected downstream customer(s), including end-user(s), installer(s), dealer(s) and/or other reseller(s) are informed and receive a copy of this notice. These parties may also contact their local Grundfos representative directly for further guidance.

Remedy

Grundfos will provide the approved remedy for affected products at no charge to the customer. Customers should contact Grundfos for guidance regarding repair or replacement options.
