Need a 24V fresh water pump

[Darkspeed]

Any advice on the best quality pump ?

[mhilley]

Jamestowndistributors.com is a good place and have a Jabsco max vsd pump on sale. I just ordered one for a customer. I have used several of them on boats (mostly european make boats - hince 24 volt.) and was always satisfied. It is 3.7 gpm which should be sufficient. They don't come cheap but quality usually doesn't.

Jabsco, 12 volt DC pumps are still great.

Thank you! Are they quiet?

They all wake up the dinosaurs. It's part of the charm.

Some noise - not much. Always use accumulator tank. Bigger the better. Brand Andy suggested are usually pretty good too. Check the gpm specs before buying.

Unless your AS has been modified. You have a 12 volt DC system, therefore you need a 12 volt pump; not 24 volt.

Going with mostly 24v systems on the rebuild

Why?

Battery bank is 24v , so for any device that is not a super light load it is easier and more efficient to go 24vdc.
I also have a lot of 24vdc components from other projects (PLC,LED,etc..) that I can re-purpose into the trailer.
I will have a DC-DC converter for the 12v loads but I want to try and limit them to as small as possible.

Looking at retrofitting one of these into a small freezer under fridge for 24v opp..

I have two 12V batteries for storage, solar panels to recharge and use the DanFoss fridge on 12V as well as the water pump and lights. Also can charge all my electronics using DC adapters without the loss of a converter.

Bill which fridge do you have?

I was also looking at this one @ AVG 40W/H - can be had in the $1200 range

24v is fine until you run into a need to cross pollinate with the rest of the world, then it might get a little "interesting". Do you run your tow vehicle on 24V too, the umbilical will be a little confused for most 12v TV's

[wkerfoot]

The one which is about 9CF.

I'm doing the same, going 24V, and have found two Shurflo 5367131 24V Extreme Freshwater Pumps (used) off of eBay. Only took two years of looking for them to come up for auction and I think I paid $60 to $75 each of them.

I've got a Vitrifrigo with the 12/24V Danfoss compressor and I think the inverter module runs a little cooler on 24V, keep it clean and cool and they last a long time - let them get dusty or without at least some fresh air 'chimney' type air flow its an expense repair. I've also got a yachty built-in BD50 unit salvaged as a spare.

I committed to 48VDC for renewable energy systems a little too early - now am stuck piecing together 24V.

I did find a boost 12-24V 3-stage battery charger, made to install near TV battery, (The better to keep line losses down) for charging while towing or emergency top-offs when boon-docking. I'm also using its 24V quick-disconnect at the A-frame as input for portable solar panels.

Thirty-feet-plus of 4awg at 12VDC & 40 amps is 5% wire run losses (one advantage to having batteries on A-frame, they're closer!) but my batteries are going above the axles, So I can reduce the wire size to 8AWG.

After all is said and done the alternator-charger-battery wire run will be nearer to 40 feet and I'd hate to use anything as heavy as 2 or 4awg beyond the built-in trailer circuit!!

Cool! I really like the big Vitrifrigo. Those are super nice and look really good.

Sounds like quite the setup!

The Flojet Sensor VSD runs on either 12v or 24v. Look it up and you'll see. Hve used one for 7-8 years now, very happy with function and noise level
