It's a grundfos selectric.

Can't see any screw except the big one in the middle which I have removed
and replaced to no avail.

It spurted out a little water and the pump rotor is visible. Seemed to be
spinning happily.

Have you bled the pump?

Should be a big (plastic?) screw you loosen to let water out. Air in

the pump can prevent water circulating.
