Hi
I've fitter new motor to Inter 2011C burner which drives Danfoss BFP 11L3 oil pump.
motor bearings are good fan rotates freely and without wobble. There's a vibration noise from the pump coupling area which I just can't seem to solve.
If I slacken the pump mounts and move it slightly noise changes but I can't seem to get it quiet.
Is there a trick to getting the pump aligned with the motor? Is the pump the problem?
Any advice will be much appreciated.
Thanks
Andy
 
Not surprised the motor bearing are good if the motor is brand new.
Was the new motor an exact replacement?
I think I know what might be wrong, but you really need to get it done by someone qualified.
Analysers show up badly burning boilers.
