Upgrading My Oil Pump

CaptPaul

I have an older Beckett AFG with a Suntec A2VA-7116. It works fine but the boiler short cycles due mainly to being oversized. I would like to upgrade to a pump with a fuel cutoff (Cleancut?) to minimize excess fuel from numerous cut-ins.
Am I able to do that without changing my current Honeywell R8284G 4009 or do I need to change the controller also?

If your existing pump cut off works fine, putting another pump on isn't going to change anything. You could just add a solenoid cut off between the pump and the nozzle line, and wire it right to orange (120v from primary) and white. It's only giving you a little better cut-off.Keep in mind that costs almost as much as a pump with a cut-off. The only upside is you wont need a pressure gauge, and you won't need to do a combustion test. If you change the pump you'll need to do both.
Better is to change the control, one that has pre-purge and post purge-and that's for any oil burner. Plus newer controls have 15 second lockout, not the 20 or 45 on the 'G'.
Even better is a buffer tank for the short cycling.

Methinks you have other issues, or you'd be better served by having a competent professional come over.

This. Depending on what boiler you have, it might be possible to reduce the firing rate as well. Where are you located?

@STEVEusaPA Thanks for your input. I know I have problems. I’m trying to sort out how and when to deal with them. We may end up switching to a heat pump system while keeping the steam system as backup which complicates things. If we do that I will likely stick to improving what I have. Either way, once the heating season is over, the system will get a good cleaning, probably a new Pressuretrol and a good inspection / combustion test by a professional. If we nix the heat pump idea I will look at optimizing the system.

@Steamhead I am in Southeastern Massachusetts. I am looking into downfiring the unit in the Spring as part of my inspection. The boiler is a circa 1960’s American Standard A3 rated for .95 GPH. I have 167.5 sp ft of EDR and the boiler is rated for 313 sq ft. It currently has a .85 nozzle. I’m thinking I may be able to go one step down depending on what the current pressure is. Does that make sense?

Heat pumps are great for 1/2 - 3/4 of the season. When the winter storms hit, you'll want that steam.

Forget derating, you need to drop 50% not 10%. Just get a properly sized and piped boiler.
