anyone know how to make an air pump pump water?
 
just wondering i would like to know if an air pump can be used to pump water to make like a waterfall.

I really dont think so. As the pump will bust or break and electrocute water that water is touching.

No. Most air pumps are operated with a diaphram moving back and forth to move air past a one way valve. Water pump, most generally are operated using an impeller to move the water.

It can be done but I don't know if you will be able to do it with the standard air pump we use for the hobby. An aircompressor or an indistrial pnuematic air pump should have enough pressure to push water up to a water fall. It is actually rather inexpensive to get a small water fountain pump to do the job without air. My dad carries them for his ceramic shop and I think they are like $30. Smal fountain pumps only run $35-60 and would push more than enough water.

Is there any specific reason you are wanting to use air for the pump?

It could be done by employing Bernouli's principle but the process would be very, very inefficient.

just get a water pump, less likly to fail unless u want to try n understand that law again :S http://en.wikipedia.org/wiki/Bernoulli's_principle

your air pump even if you use there principle will fail over time. just get a good quality water pump. it will be so much more reliable.

Check out Saeid on Utube.
He's posted a video showing how to move water with an air pump.
I haven't tried it yet, but I'm going to!:-D
