If I knew my own system was totally clean then I would fit a Wilo.
The Wilo has a plastic bearing that quickly gets worn badly by fine magnetite. Otherwise the electrical part virtually never fails.
The CP53 seems to be a good all round pump at a lower price. They both wear the bearings and fail electrically.
The Grunfoss has a ceramic bearing and a VERY hard shaft which is very resistant to wear BUT it costs about twice as much AND they have a much greater chance of failing electrically.
I have not seen enough DAB pumps and would be interested to hear of anywhere they have been used in quantity to see how reliable they are. I would not normally think of fitting them because they look cheap.
My local scrap yard is selling Grundfos pumps (or any make) from old combis for £2.00. You know it makes sense. Always have a couple of 'recon pumps' for sale.
