Powering 12VDC Diaphragm Pump with 120VAC

in-too-deep · Jul 6, 2011

Pumping herbicide concentrate out of shuttle tanks into smaller tank with a small pump. It's a pain to drag a pickup or forklift or battery over to the tank. What do I need to convert wall outlet power into 12 volts DC? Can I use a battery charger set on 10 amps or so? That doesn't seem right. Help is appreciated. Thanks folks!

Depends on how many amps the pump draws. If the amperage matches a charger will work.

I use battery chargers to run 12 volt compressors and other stuff.

A small charger will not work. Even though they are rated for a certain amps they will not start an electric motor turning. A good high capacity charger should run it without any problem. I think that the 30 amp setting would work better than the 10 amp.

I also have found that these small diaphragm pumps do not pull much load. I just use a good small lawn tractor battery. I made a small carrying case out of a small fishing tackle box. A old tool box would work too. That way I don"t have to worry about 110 volts around water/chemicals. Also some chemicals are flammable before they are mixed. A battery charger may not be the best thing to have around them.

They make a 110-120 diaphram pump

Thought about that, and we would buy one if we couldn't find a cheap way to run the 12v. Our battery charger should run it fine. Thanks, though.

A 12 Volt battery or a 12 Volt battery AND a charger is the way to go. (If you want the pump to live a long and happy life.)

what ive done in the past,is to use a battery kept maintained with a solar panel for things not used much.But just out of curiosity,,why not use a 120volt pump if you have power available?or if your pulling small sprayer with a tractor or other vehicle,why not just extend cord and plug on to it?whatever you do changing the pump will likely be best and cheapest.

dont run the pump off your charger,nobody in their right mind does this!.buy a battery ,hook both pump and charger to battery.thats the proper way ,you do it every time you start a vehicle.youll burn both your pump and charger up doing otherwise sooner than later.i assure you this setup wont be cheaper, and it will be a lot more expensive to maintain than a 120v pump.for one thing,youll have to be running charger all the time to assure battery is charged when its needed,compared to the few minutes youd be running a 120v pump.the truly right battery would cost you more than the pump,the mounting and waterproofing will add more,youll likely find chargers wont last long because of the heat they generate,and those pumps aint all that good to start with.cant figure folks who believe they can have three pieces of equipment,maintain it properly,and save money over one but if want to run the 12v for some reason just make sure it has a battery in system.

That pump that was linked to probably won't work, at least I wouldn't try it. A lot of pesticides will ruin a rubber diaphragm.

A battery charger puts out a dirty DC.Inductive kick from the motor will short the chargers diodes.A fellow who was testing ignition coils with a battery charger messed up two chargers.Back in the CB days many fellows came in with a loud hum on their signal.They were using battery chargers to run mobile units.
