Perhaps you're referring to a ram pump?

Hello John.

"The powerless pump" you refer to I believe is the Papa water-powered ram pump, designed by Water Powered Technologies Ltd. This is a much smaller and lighter version of a traditional ram pump with no mechanical moving parts.
Please visit http://www.waterpoweredtechnologies.com to find technical information and videos.
If there is any further information you require, or have questions needing answers, please reply to this post.

Here's a thread you might find useful - ram pump

Quite a few members have made their own, some from recycled materials.
