Brilliant. Product. New condition (as far as I could tell) original seal did not appear damaged. The pump worked and solved my central heating issues in one foul swoop! Superb - recommended. It was a simple swap with the old Grundfos Circulating Pump (note the old one was a different model but it fitted perfectly!)
Grundfos might not be the cheapest but they are good value.
Excellent value. Straight forward to fit. Runs quietly. My older Grundfos pump he’s run without a problem for 20 years and I will clean up and keep as a spare. Hope that the new pump gives similar service.
