Dear All.

Can anyone help?

I remember reading an American patent on lifting water using resonance it might even have been mentioned here at OUR?

I'm sure it was capable of lifting water to great heights by creating standing waves in the vertical column?

In anticipation, cheers Grum.

Would it be perhaps the Hydraulic Ram which is used for
pumping water?

The Water Hammer

Dear muDped.

Thanks for your reply but no, it's not that one. In fact I own a nice Green and Carter 1 1/2" bore pump ready for use as and when. 

Please be aware I'm working from memory but this pump had an intake box with in and out non return valves. On the top of this box it had a small electric motor driving onto a piston/diaphragm. The speed could be varied to get the correct resonance in the vertical delivery column.

I'm hoping the description might jog someone's memory as I have tried the usual search engines with no luck.

Cheers Grum.

Could it be the "Linear Resonance Pump and Methods for
Compressing Fluid?"

Or the one by I. A. Loukanov?

Thanks again........ But no...... They seem a little too modern.

However I followed the patents back without success. I might just have to build a prototype.

Cheers Grum.

but to jog more memory
