Buy a standard Grumfos 15/60 or 15/50 pump and remove the 4 allen skrews from around the motor body and separate from the pump body. Then replace the boiler pump motor with the new one. You must drain the boiler first and may have to extend the 3 core wireing slightly. Make sure the pump body is completly dry with a cloth before asembly. The price? about £60 ish.
