Bluehawk Posted March 24, 2011 Share #1 Posted March 24, 2011 Received this from a trusted online colleague today, and am passing it forward in the hope someone here might have ideas to help them with this extraordinary endeavor. [MSB] -------------------------------------------------- RFQ: An application that needs some thought. I got a call from Hawaii late yesterday. From a Mr. Brick Bradford - his request gave me a flash back and a memory of which I don't often think about. As you know I did two tours in Viet Nam 65 and 67. My brother was also there and he was in the Army (inland). We both survived - but later Larry died from complications from (AO) agent orange. My best friend George was killed over there and when I was home his father would always ask me why? My wife's Brother came back and wasn't right ever again - one day he just disappeared and no one has found him in many years. Mr. Bradford is working with the military in S.E. Asia Delta's and is still looking for the remains of our fallen Friend's, Brother's and Son's. Many are still missing (last I heard it was close to 2000). He's dredging some low land rivers in S.E. Asia where human remains were recently found. I suspect many were those who died or were killed and dumped into the rivers around those engagements. Mr. Bradford said he was on our Toyo WEB site and saw our DP pump and thought a small one might produce the results they needed to help retrieve these buried remains. I told him - I was abit taken back by the call and it startled me for a moment - it brought me back to those days. The application seems to be one that needs a pump or a Jet Pump (something with no metal or mechanical contact to the human remains). A centrifugal would most likely be more damaging to those remains they are looking for. Their last visit there they used a soft rubber impeller type pump that did some good but still destroyed much of the remains. They are finding remains but mostly they look for the teeth of which they can ID by genetic testing. All night I thought about this application - I want to help - but I can't seem to make any of our products work. Mr. Bradford thought the recessed impeller would be another option having a total non-contact design - but I said; being a vortex pump design it still allows 20% of those solids to be impacted on the impeller. He asked me if I could offer any ideas - but the only thing I could come up with would be Jet Pump design (having no moving parts and yet may provide them with the wet lift they need of (15'). He said he needs to move light sand and silt without too much disturbance more like a vacuum design where the fluid and its contents would then dump into a strainer just above water level for inspection.
