Looking for advice on what manufacturers are out there still making 32vdc heads compatible with the vacuflush system. I have several to replace on the Burger.
The VF head does not use any electricity, Just the vacuum generator pump. The head and vacuum generator only work with each other. Is it this pump motor in 32V you are looking for? Or I did not understand your question. What do you want to end up with? My Bertram is still 32V. I'm having to make things work, thankfully, NOT VF equipment.
The pump system is in working order, the toilets themselves are very old and some of the seals and foot pedals aren’t functioning. I’m not familiar with the vacuflush system as all of my previous boats have had 12v electric heads. I’m believe I just need to replace the heads and not the pump system, but I don’t know where to buy or which manufacturers are out there.
The heads are easy to rebuild, the the main seal and ball valve first check that the pumps are working: motors running, at least some vacuum building. If the motors are bad too, then you re better off switching to electric heads. Raritan Elegance are pretty good, that’s. What I used a few years ago to replace my 3 VFs. I don’t think they come in 32v though, so you ll have to either use converters or maybe set up a 12 or 24v sub panel for whatever systems you will need to convert
You may have 32V motors on your vacuum pumps. The heads are serviceable. Replacement is not necessary unless they are just ugly. There will be a new foot print that may need some deck repairs. If you really want to replace them for a later style, The later Raritan units can not be beat. Remove ALL the VF stuff and run new (better) hoses directly to the black tank. Nobody is making 32v heads anymore. Rebuilding old units (Galley Maid, Raritan) is still an option. If you do not have a heavy 24V source onboard, I have over come this on our Bertram; As intermittent as heads operate, make a DCv sub breaker panel and tap 24volts from the 3rd battery in your 32v bank. Contact me directly if you need help on this. BTW, I'll offer a few pennies for your old vacuum pumps. All else is reef material (IMO).
