the pump may feel like it's spinning but in actual fact the impeler can detatch it'self inside the pump.
isolate each side of the pump & remove pump body & check. other than it may have a blockage in the pipework.

What state is the heatexchanger in? may need replacing.

Have you tried balancing the system rads?
