Much like a ram pump then.... the waste. I started realising that. Needs a river or stream. My river is too fast and too deep. Can't build a Mon, 19 Oct 2009 04:37:49 GMT Timothy Alm http://tech.groups.yahoo.com/group/pulserpump/message/72 http://tech.groups.yahoo.com/group/pulserpump/message/72 No; water can not be effectively recycled in a closed system of this type. This principle requires quite a bit more moving water than is pumped.

So you need a "tromp" in the stream and it provides the compressed air to work the Mon, 19 Oct 2009 01:01:50 GMT Brian White http://tech.groups.yahoo.com/group/pulserpump/message/70 http://tech.groups.yahoo.com/group/pulserpump/message/70 I did try something like steps over the years. The problem is the steps cause pressure drop. I found the best way seems to be either straight up or at a Mon, 19 Oct 2009 00:37:11 GMT cyara2408 http://tech.groups.yahoo.com/group/pulserpump/message/69 http://tech.groups.yahoo.com/group/pulserpump/message/69 Can water be recycled in a closed system? Say from sump.... down 1st pipe into Pulser pump chamber..... up 2nd air and water mix to a high top tank using coils Mon, 19 Oct 2009 00:36:42 GMT cyara2408 http://tech.groups.yahoo.com/group/pulserpump/message/68 http://tech.groups.yahoo.com/group/pulserpump/message/68 Much like how a coil pump works. Also called a spiral pump. Is a neat concept. It works perfectly in a river as a wheel... just coil the piping bigger and Sat, 17 Oct 2009 22:28:54 GMT cyara2408 http://tech.groups.yahoo.com/group/pulserpump/message/66 http://tech.groups.yahoo.com/group/pulserpump/message/66 This is really neat! I want to see if I can use this in an aquaponics system to get the water from my sump back up to my fish. I am only starting to build.

Matt in Cornwall obliged a few months ago.

This pump is simple and easy to make. I used leftover materials from other projects. This is
