Electrical help needed

I don't know a lot about electrical circuits, but I would like to use the following pump in a standard wall outlet (has higher head pressure than standard aquarium pumps).


I am looking to buy an AC to DC adapter to run the pump. The pumps electrical requirements are as followed,

Nominal voltage 12 V DC
Operating voltage range 8 to 24 VDC
Nominal power (@ 12 V) 24 W
Nominal current (@ 12 V) 2 amps

would this one work, the part that throws me off is the mA,

RadioShack.com - Power & Batteries: Adapters: AC (Home) adapters: 3-12VDC/800mA Regulated AC-to-DC Adapter

Yeah that adapter won't work. It is only rated for 800 milliamp. Your pump draws 2 amps @ 12v according to the specs.

This can be done, but it takes a different power supply, not this one. You need 2 amps, which is 2000 miliamps. Radio Shack probably has a 2000 miliamp unit if you search hard enough for it. If it is a variable voltage supply you can control the output of the pump by changing the voltage. Incidentally, I use that Radio Shack power supply to power my fan in my hood, and it works great. But, you need a bigger version of that.

Wont work. You need more amps. Look for 2000mA or 2A.

Something like this.
Good luck!

Bit late now but the link still applies!

Or something like this: RadioShack.com - Cables, Parts & Connectors: Component parts: Relays & transformers: 12.6V CT 3.0A Chassis-Mount Transformer with Leads if you want to go the cheapest route.

Guess I'm missing something, but why use a 12v 2a pump ?
I bought a 1000GPH pond pump with a 24ft max. head for less than this pump, and plugged it in the wall. No extra power converter needed.
At 317GPH and 10ft max. head, it doesn't really seem to be that much of a pump for the price. How much height do you need. At 50 psi, I hope all your hose connection points are bulletproof, and you have surfboards for your fish.

I'm using it as a booster pump for the mazzei venturi. I needed something with high pressure, but low flow (20 gallon, 300gph).
