need a way to power a pump without running extension cord

[brah]

need to figure out how to have power to a pump,, any suggestions?


im assuming solar stuff is somewhat expensive,, but really dont know anything about it..maybe some sort of trickle charger with a battery??

dunno

You could run a small 12v pump (Bilge pump) off a car battery for quite a while
if you had a timer or cycled it on and off. You could get a small solar panel for it
too. Check westmarine... But you could probably get it cheaper...

yes!

yes!

rep for you man, you just helped my grow out... i think i may be buying a "Water-Buster Battery-Powered Pump" from www.westmarine.com to help me out with watering my crops.

That's cool. I don't know about that pump though. Might be a little weak.
I'd go for their smallest bilge pump and a motorcycle batt...

thank you! im going to do some research tomorrow about this

Some pumps use very little elecricity.

Dont discount the solar stuff. A friend that happens to be a camping enthusiast has a 4' sqaure of solar panels that folds into a 1' package. It is sold by camping sites and even on a cloudy day will produce enough electric to run a coffe pot or small fan. On sunny days the little panel can power a small Tv and hair dryer. I think he paid about 40 bucks for it. The advertisement showed a rugged campsite making coffee and watching tv.

NICE toker, ill check camping stuff too



someone was also telling me that solar stuff is pretty heavy-duty too, he said that the electronic gate like for a gated community is solar powered in a local neighborhood,,im going to look into it .

really good idea Kcar! Im gonna consider this myself for the outdoor fruits & veggies.

DC to AC converter attached to a 12v battery.

 

[Kcar]

It's called an Inverter, and you wouldn't put it in between. And Inverters are ineffecient
anyways. Stay with DC all the way.

 

[dazednconfused]

Considering the thread's title, the DC to AC method sounded like an appropriate alternative if you already had a 120v pump. Although the efficiency may not be the best, you can say the same with solar panels as you just increased your exposure.

Needless to say, my 4.5gpm diaphragm pump runs efficiently off those 12v DC batteries. Well worth the $150 spent.

 

[jocbear]

hey dazed, what kind of lift do you get with that setup?

im not opposed to getting a new pump to run more efficiently

do you have a link to a similar pump and explain how youve got your setup??

also how long do the batteries last??

 

[dazednconfused]

The battery I use is rated at 20 amp hours. Since the pump draws approximately 9.5 amperes, the battery life is roughly 2 hours. This is fine because it only takes less than 10 minutes to water with a 1/2" irrigation system. It states the max lift is 35' which is decent but I'm sure it could go slightly higher if you had to. The pump is from dudadiesel.com, they have two models to choose from. Both come in 115v/220v AC and 12v/24v DC so it accommodates the consumer nicely.

This is what their website had to say:

"Testing was done on a system with 35 feet of max height, 200 feet of head, 3/4" garden hose with water. Approx flow rate = 2 gpm. No suction lift (pump placed below water source.)"

I take it a gas pump is out of the question? What kind of flow/lift do you need?
