Hydra Cell D10 Pump for Watermaker

[ColdEH]

Hi there just thought i would post my pics here as well . D10 Hydra cell pump on a 12v dual belt clutch running at 600 to 800 rpm of my Yanmar ex generator engine .

Nice lookin unit, did you build it?

[ColdEH]

Thanks , Yes its my design and build. There's more to it of course, it's all in a soundproof enclosure now, double sprung . The alternator puts out 260 amps at 1800 rpm it's an Ecotech . I actually just sent the regulator out to them to get it the voltage set point changed to 13.8 v for use with LiFePo4 batteries .

The water maker is fully automatic with an automatic flush as well. 40 gallons an hour . The pump is only working at about 40% of it's capacity , takes about 3hp to spin it when it is engaged .

Very nice work. If only I had space for such a unit.

Sweet. I wish I had that kind of room as well. But it looks like the picture makes it appear a bit larger than it actually is. Is the alternator clutched as well? Plus I see another alternator up front?

Actually the alternator is driven directly off the crank shaft via a LoveJoy connection. It takes almost 8 HP to spin it under load so I really didn't want to have to worry about belts and also the side load that it would create on the end crankshaft bearing. The engineering was a little tricky but it all runs smooth and quiet .

It was hard to find an alternator that makes big power at very low rpm . Echotec being the only one . The Yanmar runs a steady 1800 rpm as it was from a 8 KW Kohler Genset . The engine had 100 hrs on it when i came across it . Essentially brand new.

I have now installed an aluminium umbrella over the alternator just in case I get any leaks from the pump .

I have it now in a soundshield box , the whole thing measures 45" long 22" wide 26" high .

The alternator in the front is a standard 35 amp unit used just to charge the start battery. The Echotec only charges the house batteries.

How large a boat is this going in? I'm a rare one here but I enjoy the fab and custom building far more than the sailing. I get 6 months away from my shop and I am so bored. A sunny island paradise is so empty without a welder and drill press. Once again, nice work.

Thanks man , I have seen so many crap 20000$ water makers , there had to be a better way .

Believe it or not this will fit in a 1994 Hunter Passage 42 , . will be heading South myself in 4 years , going to take quality stuff with me , hopefully nothing breaks to often

Regards

Yes I get a little bored as well in the winter LOL

Forget the Hunter , spent the extra and got a Bristol

I was just thinking of your watermaker set up the other day and was wondering how you were coming along with the expectant launch date.

Hey Tellie. I just moved my hot water tank out of my engine room last weekend , what a place to put it LOL.

This weekend will be building up the beds/mounts for that generator . I am very excited to get all this stuff up and running .

Do you know of anyone that used a hydra cell pump in a water maker?

I saw one once in a Trintella at a boat show in Annapolis , it was good to see im not totally nuts .

Typhoon kudos on your "build". I am now building my combo dc generator/water desalinater, and your build influenced my decisions on how to accomplish this to the level I need and want. Ebay just delivered to me a D-10 Hydra cell...these pumps are bullet proof..can even be run dry. Craigslist presented me with a Kubota tractor frame with a 236 hour D782 20hp Diesel engine.
My challenge is the flywheel coupler. Hayes wants $780 for their bellhousing setup..nice but man is that expensive. But at least I have a plan b with them if nothing else surfaces for solving this aspect of the build.
The assembly needs to fit through a 24x19 Lazarette deck opening making my challenges slightly different than your build, but doable with the mini diesel engine and a small length stub or jack shaft.
Again nice job on your build, literally inspiring..

Thanks very much the kind words.
Yes the Hydra cell pump is bullet proof for a water maker, even at 40 gallons an hour it is hardly working , and never a problem with oil leaking by the pistons and crapping out your membranes .
Post a few pics of your build maybe I can give you a few Idea's
Oh and the generator is in the boat now and awaiting exhaust hookup

Hi Typhoon, did you get your unit operational? Looks like a fantastic piece of equipment. What was the D-10 pump model you used? It looks like a brass head. I priced a SS head (model D10EKSTSNECB) and it was really expensive. Just wanted to get your specs - I expect there will be little to no issue with brass provided it is flushed after use.
How is the unit working?
Thanks for the info.

Yes I was thinking of a stainless pump as well , but the price . These things make so much water you can really give the system a good flush after every use , so I went with the brass head pump. I will get the model off the top and post it .

The system is all installed , i will snap a photo of the control panel and post it this weekend . I'm still in fresh water so I have yet to install the membranes in the pressure vessels and commission the setup . That will come as soon as I get into the salt , it all looks great , looking forward to getting it wet.
