Riello RDB oil pumps

The paste didn't show water as present, but it might well be because of the chemical. I didn't do a pH test. Don't think I'll be back to find out - the owner was, "interesting".

The clumping could be bacterial contamination. That can show as a clumping of debris which is actually biomass/bacteria.

I've been asked to look at a system that has had some work done by a previous engineer. The boiler was suffering from flame-outs and the previous guy ended up replacing the oil pump. The boiler is still cutting out, and after checking the usual suspects, (oil pressure, water in tank, pump pressure, nozzle, etc) it looks like the solenoid valve isn't allowing sufficient oil at the nozzle. It sounds suspiciously like the previous symptoms, but this is apparently a brand new pump, so before I replace it, does anyone know the specification for the valve to check it's within bounds (spring force, actuation distance)? It's an RDB 1. Thanks

replace the solenoid the magnet could be gone they're only £29 and also replace the nozzle.. and also check the oil for water

I wouldn't pay £29 for an RDB solenoid. That must be retail price

£29 for a solenoid. That's a good one. I don't even charge them to my custs for that.
