Adding more ballast pumps

[eder10986]

I got to thinking yesterday….we have a 17 SA with three pumps. Think I could plumb 3 more into our current system? I’m good with plumbing and decent with electrical stuff. Thoughts?

Short answer, yes. I think the biggest hurdle is going to be having an unused port on the sac/tank for filling/draining.

Maybe I’m under thinking the project. I was thinking I could plumb them in series with the same fill port tube. Maybe not?

You will gain very little if any by doing 2 pumps in series on a single hose.

Need to basically run a second pump and hose to each bag.

The only gain is going to be parallel pumps or higher capacity pumps. With 2 pumps in series, your final flow rate is likely going to be that of the last pump, rather then summed flow rate of the 2 pumps.

Now that I think about it this totally makes sense.

I’ve got done planning to do if I do this. Might try to tackle it in the winter time when I take the bags off.

What about the electric? Can I just splice in-line or will that trip a fuse?

Start up amps on a jabsco puppy pump is around 20 amps. You may need to upgrade breakers.


Perhaps upgrade to a jabsco king pump?

King 15GPM
Puppy 9 GPM

Not a bad idea. If I had 3 kings would the breakers still be good or would I need to upgrade?

Hrmmm, maybe kings are only 11 gpm and they would require a 25amp circuit versus a 20amp.https://uploads.tapatalk-cdn.com/20210704/4e8e15db56da36eb17949620f45dbdd2.jpg

Thanks bro. Looks like I’m back to planning plan A of 6 puppies in parallel.

If im not mistake, the pumps are driven by a PDM. Not sure whats rating is, so adding more pumps or larger pumps, would likely not be plug n ply eclectically wise.

I'd run through you setup to see if you can move to Kings, definitely worth the upgrade IMO. Check your hose size, wire size and fuse size, etc. Post up what you find and I'm sure we can work through the numbers. It's very likely they can handle the jump to Kings.

1” tubing has a theoretical flow rate of 23-27 gpm at 60-90 psi, so the kings would be the simplest means to decrease fill time.

In a parallel installation, you can easily over pump the supply rate that the thru-hulls can provide as the screens and internal diameter of the fittings will cause friction loss, along with any fittings, bends, or disruption in laminar flow.

Thanks fellas. I’ll look through all y’all mentioned and see how it is wired and such as soon as I can.

Honestly if the kings will cut my time even by a few minutes it’s worth the investment. I can always sell the puppies or keep them as a backup.

The lake we frequent has a very low bridge we need to go under to reach the best part of the lake. We need to fold down our tower AND have full ballast to get underneath the bridge.

The crap part is that the only launch is on the lower side of the bridge. It’s actually an awesome lake too with a lot of money so rumors have it they’re breaking ground to build a launch on the upper part of the lake. We’ll see!

What lake if you don't mind sharing?

Spend most of the time in Hyco lake in Semora. Person co.

A guy on the Supra page built a system for those big pumps, new wire, plumbing, and fuses, etc.

3 mins for 1280#s bags. Those pumps move some water.

I know someone else that put 3 in his 24 Launch. Ripped everything out and replaced all the core components.https://uploads.tapatalk-cdn.com/20210706/3900f2b2bf939f4bd2ba7b7556d662d6.jpg

Wow. I’m interested in this for sure. Perhaps a winter project for me

Supra Facebook or forum? Not on Facebook but wife is so if you could direct me where to find the info I would very much appreciated.

I'm wrapping up installing a Talulah pump to one bag in my 22v and running the existing 2 pumps to the other bag. I can tell you the 1-1/2 is way harder to work with than the 1" hose.

If you don’t increase the thru-hull size proportionately, you won’t get any size-able decrease in fill time. A 1” thru-hull can only handle a certain amount of volume through it.

Ha. This project is looking more grim and costly the more I read. I sure do appreciate the help!

Sure is, but that is what’s going to give you the flow on high volume pumps.
