Outdoor water fountain...how to silence homemade pump

Hi Guys,

I love this website. I've been living in Egypt and can't really do all the hobbies that I love. We recently moved and I have a little patio area. So I wanted to build a waterfall. It's 10 feet high and I didn't realize it would be such a futile task trying to find a water pump that will pump that high.

So I decided to make one.

I attached some images showing the centrifugal pump made from two plastic containers, a water bottle, plastic coat hanger, and construction adhesive that is driven by a drill. It works really well. It gets up to the twelve feet I currently have the hose running up to.

But in order to do this, the drill has to be almost full speed which is obnoxiously loud. 

I'm looking for some ideas on either how to silence the drill motor, or go a different route. I have to rebuild the shaft as I snapped the plastic rod (hanger) I was using, so I'm open to some rebuild ideas.

Thanks so much for the input!

I'll post a tutorial once I get a fully functional, stable, and practical prototype.

Any induction motor will be quieter than a drill.
I love your pump design.
Amazing work...got impressed. Keep up thr good work and enlighten us with great ideas.

I'm impressed with your device.

I agree that a commercial pump oughta be able to do 10 ft.

Nonetheless. If you want to silence the 1 you made, perhaps a double walled box around the whole thing with insulation between inner and outer wall.

I have to say that you made a very good prototype for a pump. I have to agree with Kiteman that a commercial submersible pump is your best option if you want a quieter pump.

If you want it silent, you're going to have to use a different kind of pump. A submersible pump should easily get you a head of 10 feet - here is one that will pump well over a hundred feet straight up, and this cheaper one pumps over 20 feet.
