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.

If there is any further information you require, or have questions needing answers, please reply to this post.
