Big Electric motor supply help...

[MCummings]

I need some help from some of our resident electric experts.



I am looking at purchasing an electric water pump, 108GPM, and 1. 5HP @ 110V or 230V @60Hz+

This pump here



I am going to be pumping some water on dirt pads just enough to keep the dust down. I will have a 2,600 gallon water tank that I will use to water down pads from 100'x100' all the way up to 500'x500', and some stretches of roads.

The Tank on this page @ 2,635 gallons



I want an electric pump, and electric valves so I can control everything from in cab without having to get out and start a gas motor, etc.





Here is what I was GOING to do, but I'm not sure if it's the RIGHT thing to do.



I was going to hook up 10 Yellow Top Optima Batteris in Series (120V), to power the pump. Each Yellow Top has a RC of 155 minutes @ 20Amp/h drain.



I think this would work, but not sure. I have run into a mental road block, and would like some input from yall.





IF this setup works, my main question and concern is: How to charge these batteries? I would like to use a Solar panel/Maintainer charger for days the unit is not in use, but would also like to charge the batteries when I plug into the truck at the light connection.



I would assume that 10 Yellow tops would be more than overkill for this pump.

Judging by how much water I would be laying down, at full pump capacity, it looks like it would take atleast 20 minutes to lay down all my water.



Can somebody tell me if the battery/pump combo will work?



If I have enough capacity left over I would like to run a water cooler (Like a Porta-cool unit) for about 2 hours (max).

Something like these two,

Port-a-cool 16" 3-speed cooler

Port-a-cool 1/4 HP cooler





I can still be hooked up to my truck while running these units. I'm not sure if that would help enough or not.



Thanks guys! I really apprecaite it!

Merrick,



10 each 12VDC batteries hooked in series will produce 120VDC - Direct Current. The pump you describe needs 120VAC - Alternating Current. At 100% efficiency, 1. 5 HP = 1. 119kW, so you would need a 1. 25kW continuous or larger DC-to-AC inverter that was peak rated to handle the inrush current of this electric motor if you were going to power it with batteries.



Why not use a Honda EU2000 or EU3000 generator (try before you buy to ensure the 2000 will start the motor).

Most water trucks around here use a mechanical pump driven off a PTO. Should be able to find one to fit your NV5600.

I did forget about the AC/DC deal. I've been looking for DC > AC Converters, but the only thing people want to sell me is 12V DC to 110V AC.



I don't want to run a PTO because in the near future I will be pulling with a different truck. I also hope to expand soon, so I will be making more trailers and getting more trucks. If I could set a stand alone unit (trailer) to be pulled by a 1-ton truck, it would simplify business greatly.



Also, PTO's require a set RPM, and I will be driving around a pad with complicated turns, and needing to back up, etc. and I need to turn the water off when I stop to prevent puddling.



It needs to be the most professional water job, otherwise we can just get a 130Bbl Water truck come out and flood the jobsite like we have been doing.





I found THIS , but I think the RPM cannot fluctuate too much (as in driving from 1,000RPM to 2,500RPM) without damaging the generator.



If my options start to fade, I can put a generator on my trailer, but, I will have to haul "chemicals", plus the power is not "replenishable" like Battery power. (If I put a generator on my trailer, I'm looking at THESE (to stick with Diesel, since gaoline units are not favorable with Chevron Production)

 

[RustyJC]

If you go the generator route, Onan (owned by Cummins) has quite a few diesel generators to offer.

12v-120v converters are OK. You can also gang the batteries together in parallel to keep 12VDC but boost the amperage - just like your 2 batteries in your CTD. Could also charge them off the 12 VDC trailer connector on your CTD (or any other tow vehicle). Just make sure the inverter can handle the amp draw of the motor.

 

[MCummings]

Wow Rusty, Thanks for the help,



I just found THESE AC/DC INVERTERS by ONAN



Found a 3000kW AC/DC deal there. I'm trying to figure out how it works...



Keep the info coming,, I've gotten farther in the last 45 minutes than I did in the last 2 days, LOL.

EDIT: Looks like I would wire the batts up in parallel instead of series? Thanks nps.



How many batts would I need to get about 20 amp/hour drain from the batts at ~1. 5kW ?

 

[MCummings]

Here's ONE , although, I haven't heard of that name brand before.



The Inverter would need to be for Severe duty as I will be traveling incredibly rough terrain with some speed, and my trialer will be right in the ball park of 25,000Lbs at full capacity, and roughly 6,000Lbs empty.

On the batteries, make sure you use deep cycle batteries. How will you re-charge them? Solar?

I have a buddy who has a place up in the mountains, he uses 6 deep cycle 2 volt batteries in series. Which equals 12 volt, then uses an invertor to kick it up to 120 V. He has a couple of good sized solar panels which keep everything charged. It is a great working system.

I believe the 2 volt batteries last longer (in years) and you get more hours of use per charge. http://www.backwoodssolar.com/Catalogpages2/battery2.htm#BATTERIES

 

[MCummings]

They will be the Commercial Optima Yellow Tops.



These Here.





I will maintain them with Solar ($59. 99 for a Solar maintainer), and charge them from the truck.

EDIT: Maybe that Trojan T-105 225amp/hr battery (6v) would work real sweet?

 

[nps]

Yeah - you'd need to wire pairs of 2 in series to get from 6V to 12V, then wire the pair in parallel to get the amps. 4 or better yet 6 batteries should do it based on the specs of the inverter - says it's 90% eff.

 

[Elite1]

I guess it depends on how long you need to run the pump between charges...

Optima Yellow 12v rated at 155 amp. MINUTES

Trojan T-105, 6v, 225 amp hours

Trojan L-16 HC, 6v, 420 amp hours

Surrette B-KS-33, 2v, 1700 amp hours

 

[MCummings]

Well, I've changed my tank size today after some field observations. Seems a 2,000 Gallon tank will be more than enough, maybe even a 1,600 gallon tank



Even at full pump capacity of ~100GPM, it would take no more than 20 minutes to unload all my water.



20 minutes at a time, with minimum 1 hour break between pumping. No more than 2 pumpings in one day.



I like the Yellow tops for the descent price, "autozone" availability, sealed, and the ability to witstand over 8,000 Hours of vibration and still work fine compared to conventional batteries failing in the 3,000 hour zone.
