Riello RDB Oil Pump Problem?

[Luke]

Hello all this is my first post and am a big fan of the forum

I Fitted a New riello rdb pump aprox four weeks ago to replace one that was leaking oil, was phoned and told that now 4 weeks on the burner is making a screetching noise. checked out the motor and pump, and it would seem the new 4 week old pump is turning a bit stiff has any 1 els had this problem??
Pump was set up with oil guage and boiler serviced at time with fga new nozzle hose etc
any advice appreciated

Not had any problems recently, but not to say there aren't any round the corner. What was the pump filter (behind end cover) like? and pump vacuum pressure?

 

[Luke]

pump filter was spotless. vacuum gauge is out of action (knackerd) You thinking of possible resistance in the oil line ? has anyone seen a new riello oil pump get stiff in a matter of weeks lately? my supplier is in inverness

Did you test the motor and pump unattached?

It can often be difficult to discover which is noisy when coupled together.

Could be the drive dog slipping also but unlikely, or even the fan scraping
the case (this can easily be checked with motor decoupled).

As above, could be the motor bearings especially if the pump was leaking - the kero sucks straight into them and dries them out. You can often 'cure' it with a dro pof 3in1 onto the bearing. As mentioned above, pop the pump off and run the burner for a mo to identify where its coming from. Dont be too sucked into the feel of the pump, when you rotate them with your hands they often feel a bit knackered but its just the pump movement.

yea i had the pump off and ran the motor/fan no problems , problem is intermittent tho but pump is definetly a bit rough/sticky cant understand why tho because it is only 4 weeks old

cant understand why tho because it is only 4 weeks old

I bought a telly once from John Lewis. Had a fault occur within a few weeks, they changed it. Just one of those things.
Stick a new pump on but dont bother setting up til youve run it and heard it.

i wonder would Grant Spares cover the cost of new pump and fitting ? dont see how it should be my customers problem or myn
