cwr Posted January 25 Share Posted January 25 Hi all I need to replace this oil pump from a boiler. It's a Danfoss, I can tell that much.... Unsurprisingly there appears to be a multitude of possible models it could be. Ideas ideas if where to go from here? Link to comment Share on other sites More sharing options...
marshian Posted January 25 Share Posted January 25 Send a picture to Danfoss and ask them?? Google "images" Danfoss oil pumps and see if you can match it on the web and see where the links take you Link to comment Share on other sites More sharing options...

Looks very similar to BFP 21 L 3 071N0156 https://www.ebay.co.uk/itm/325254847243?hash=item4bbab31b0b:g:DyIAAOSwBjti0B65 Link to comment Share on other sites More sharing options...
dpmiller Posted January 26 Share Posted January 26 (edited) tell us what burner and boiler it is, and do you know the direction of rotation? or if you're stuck there's always https://www.bes.co.uk/universal-oil-pump-16393/ Edited January 26 by dpmiller Link to comment Share on other sites More sharing options...
cwr Posted January 26 Author Share Posted January 26 Yes, but there are a number of models it looks similar to. Link to comment Share on other sites More sharing options...
cwr Posted January 26 Author Share Posted January 26 Actually, looking at the data sheets they're not all the same, will study some more. Is it safe to assume the drive to them is all the same? Link to comment Share on other sites More sharing options...
cwr Posted January 26 Author Share Posted January 26 I don't have a photo of it to hand, but the burner's model number has also disappeared over time... Link to comment Share on other sites More sharing options...

Unsurprisingly there appears to be a multitude of possible models it could be. Ideas ideas if where to go from here? Why do you need to replace it, what part of it has failed? I only ask as I repaired a drive shaft/gear spline/key on one of these not long ago, it was pulsing the oil pressure and it turned out to be the gear slipping on the drive shaft.

cwr Posted January 26 Author Share Posted January 26 It had sized up. Tried freeing it, but it's not great and still too stiff with the screws tightned. Looks a bit corroded inside. Link to comment Share on other sites More sharing options...
dpmiller Posted January 27 Share Posted January 27 the mount and shaft *should* be universal but there are some outliers. Direction of rotation and pipe positions are the critical bit, some of the other options (position of the regulator etc) may not be so important for most applications...
