Hi
I've just fitted a Danfoss oil pump on a domestic burner. The boiler seems to be working just fine but the pump seems to be overheating. Any ideas?

They do get pretty hot due to their location but the kero passing through keeps the internals healthy.
Which burner do you have?
John :)
 
Did you set it up correctly, using a pressure gauge and flue gas analyser, or did you just lob it in and hope for the best?
 
I don't know which burner it is but it's an old one I was hoping to keep going for a few months until some building work is complete when I am getting gas installed. There was black smoke coming out of the flue and I had a pump lying around so I just lobbed it in and hoped for the best (fixed the black smoke btw). The motor is on its way out too so I'm just going to give it up and hope the weather will get better or find a second hand burner and replace it with that. So, thanks for the replies folks but no need to keep this thread going.

Cheers Bob. Which part shouldn't be tightened too much, nozzle, oil input or pump to motor chassis? I suppose it would make sense not to tighten any of those too much.

I think Bob will mean the pump mounting system, usually a few allen screws. Incorrect tightening here can cause excess friction and sometimes means the motor won’t start at all.
(Sorry for the gatecrash, Bob has forgotten more than I’ll ever know (y))

Yeah, there's three allen screws. I tried to turn each the same number of times as not to mis-align the pump with the motor. The motor does work when you give it a bit of a push and will work for a time before ceasing and locking the system. I wonder if that's the reason. Ta much Burnerman.
 
No worries - keep those screws on the slack side......it isn’t the best engineering I’ve ever seen!
