Grundfos Central Heating Pump Weak?

Discuss Grundfos Central Heating Pump Weak? in the UK Plumbers Forums area at Plumbers Forums

Do central heating pumps lose their strength over several years and is it worth taking it apart and servicing it?
Are the two seals either end 1 1/2 inch or 1 1/3 inch?

What's the latest central heating pump should I need to replace mine (photo) like for like?

No I'm not a big fan mate your old pump is not energy efficient the new Grundfoss pump are quite a bit more expensive and in my opinion Dab are just as good . Kop
