Product ideas for low-flow and high head configurations

Product ideas for low-flow and high head configurations

Product ideas for low-flow and high head configurations

(OP)
I have an application in a developing country.  The site has no access to electricity, so the pump will need to be powered by a diesel generator or other source.  Total head is approximately 300 ft. and the maximum available flow is 8 gpm.

Can you suggest any products that can work with these conditions?  Pumps, power sources, etc?

Ideally, the pump needs to last 25 years or so (with scheduled maintenance, of course).

Any ideas are much appreciated.

A ram pump or wind turbine.

Diesel.. Yuck.  Lots of maintenance and fuel and oil over a lifetime.

What size??

I'm assuming that the goal is to pump water from a deep well, and it's not a real gusher of a well, either.

I'm thinking a horizontal axis windmill, and 600 feet of chain with tin can 'buckets' wired on.
 
I guess you need to import the chain, the wildcat, a shaft and a couple of pillow blocks.  The rest you can probably fab from local materials.

Based on the limited detail we have to date, your suggestion looks to be the best answer however, in the event of getting some useful information we may be able to make a better selection.   

RE: Product ideas for low-flow and high head configurations

oh.. 8gpm.  I didn't see that at first.

There are some solar run well pump systems that move water a little slower than that but close.

You should consider a solar driven submersible, or a few, as then you could have a graceful failure.  One could fail and still leave you with some water rather than the diesel throwing a rod and leaving you out completely until repairs can be done.

8gpm - How many gallons a day?  Did you plan on running the diesel continuously?

I put one in The Gambia 2 years ago.
As my cat always says, "Purrrrr-fect".

Solar.  Previous setup was a 200 VDC motor they salvaged from somewhere and they were holding the wires together to run the pump, because the disconnect & breakers were too expensive.
