Suitable replacement for Myson CP63?

Would this fit and work as a direct replacement for my current 22 year old Myson cp63? It’s a bit temperamental now and when it does work it sounds like a jet engine so I think it’s time to give in and replace it.
Asked by: Flockhead

Can I add this pump to system and keep the original pump running at the same time

Asked by: Farshid

Does the small 3 pin second electrical connector require a cover against water ingress?

If so can I fill it with a silicon sealer?
Asked by: Toshmarple

can a central heating pump appear to be behaving normally yet have lost some of its force?

I have a grundfos pump about 6 years old and it runs quietly it vibrates gently and the pump and pipes both sides are hot, so presumably it is pushing water through. But some rads stay cold. .
Asked by: gagt
Turn off power to pump , take out centre screw , ( catch water in a bowl at same time) Put a small screwdriver in the shaft of the pump. Hold screwdriver tight and switch pump back on , If you can hold the pump from spinning , then pump is underperforming and needs replacing . If you cant hold it back and it spins screwdriver out of your hand , then its fine. Put centre screw back in.
