Hello, If you are looking at a ram pump (my family were building them from about 1860) it's going to be a very large lump of kit 6" or larger drive pipe, so I would go for a small turbine driven pump that you could pick up with one hand. You should get a delivery of 20 to 25 gpm at 75ft head. Rams are nice in small sizes if the flow is constant, clean and known. Introduce any variables such as eels, leaves or varying delivery pressure and they just stop. Rupert Evans Engineering UK [EMAIL PROTECTED]
-----Original Message----- From: tm9214080 [mailto:[EMAIL PROTECTED] Sent: 31 October 2004 13:23 To: [EMAIL PROTECTED] Subject: [microhydro] Ram Pumps I am looking for SPECIFIC design information for ram pumps. All of my internet searches turn up general information or designs for particular ram pumps, but they do not give me the information I need to design and build a pump customized to my situation. I see 2 books listed on this site: A Manual on the Hydraulic Ram for Pumping Water author S.B. Watt Hydraulic rams - a comparative investigation author J. Tacke Can anyone recommend either of these for my needs? My particulars are: Drive head=7 feet drive volume= 500 gpm delivery head= 75 feet delivery pipe (now in place)= 500 feet of 2 inch pvc I want to get maximum delivery from this. I am assuming, perhaps wrongly, that ram pump will be the best method but perhaps there are more efficient ways to harness this power for pumping water.
