Time to try to fry a pump

[Lycof]

Ran an 1100 GPH bilge pump for 5 hours at 20 Volts. It was SCREAMING and didn't skip a beat. Going to run it on my little subbie on tuesday, will see how it works. Have a spare en-route incase it goes up in flames.

Looking at 3d printing a better impeller for it to try also. Will most likely be a royal PITA to get it right, but gonna do it.

You've just created the Binford 2000 turbo pump.....More Power!!

If you have the patience with the printer, maybe a design like the pump on a jet boat using a tapered cone volute/liner and matching tapered screw impeller with a very close tolerance....just a thought I've had for a long time but not the resources to produce one.

Yes! Thank you Mike! It will take some time, but consider it done! If you have CAD skills and need an item printed that fits in a 6 inch square box, drop me a line. Just remember, 3d printers have limitations that 5 axis CNC machines don't.

If this goes well, I am going to get a 3750 gph and crank it up. I am running the one I have on a dewalt 20v lithium 3a battery. I have two, so just recharging the spare in the 45 minutes it takes to drain one.

You can use 2 12V batteries in series and get 24Volts....Super charged
