Riello 40 oil pump

[Roger Welton]

What was the filter housing like on the old pump, tide mark, dirty?

Some have done that by changing a fitting over on the pump, I think & fitting the coil with the nut upside down or something, if I remember right.
Not much point in doing that if you can get an RDB pump, - you would have to be an idiot, tbh, but one engineer told me to use the 40 pump as it is £1 cheaper!!!!
Now, putting a Danfoss pump on a Riello burner, that's a wee bit harder!

something is causing a problem here then if pumps keep failing, dirt, water tank height issues pulling air through. air ingress. r you oil engineer or diy

Riello pumps are poor & it's a lottery how long they last. That said, as you say, a clean oil supply, paper element filter & probably a tigerloop will maybe help them last.

Pump filter clear, as was tank filter. Have heard rdb pumps have been causing problems of late, possibly connected to the altered composition of kero.

the kerosene low sulphur issues affect vapourising burners in various amounts but havent heard that it causes pump breakdowns or wed have a lot more work.

All Riello pumps have been causing problems for years & with spells of major troubles. Not fit for purpose using Kero IMO & other pumps, like Danfoss don't have this problem.
If a new burner that used a Danfoss pump was suitable (like a Sterling), it would work out a lot cheaper than changing Riello pumps every 2 or 3 years!

It does create a lot of breakdowns. If you open a fairly new Riello pump & look at the gears, you will find the drive pin worn where it hits the gear & it is often shiney at one side where it is twisting. The first gear will have a gouge out of it where the drive pin has cut in.

I agree with you on the Danfoss pumps. I would never fit a new Riello unless specifically requested. it's the Electro Oil Sterling every time.

Yes, it's amazing generally how reliable the Electroil burners are & the Danfoss pumps are often lasting well over 15 years. Danfoss are a lot cheaper also. Only thing that often gives trouble is the Danfoss solenoid.

Unfortunately (or should that be 'ironically') reliability ain't good for business.

That's so true. And Riello burners are now on loads new boilers.

I've though it would be good if danfoss would make a 'riello compatible pump, I'm sure they would sell well given the number of riello burners around nowadays.

 

[obleo]

That would be a definite winner.

Have wondered for years why Danfoss didn't, or couldn't do a substitute for Riello pumps. Don't think there should be a legal problem but maybe they think it is not the way to do things.
There was Pumps that did Riellos that were Chinese but were probably illegal as were boxed as Riellos.

To think that a lot of people will be replacing a decent standard efficiency boiler that has a reliable burner, to a new condensing boiler, partly to save oil & then find their new Riello burner needs a new oil pump often!
Seems it might be a case of - save a £100 a year on oil & spend it on new pumps!
