    Pump w/resevoir

    Would there be a recomendation for a pump to fill a resevoir. The pump would not be under pressure. Is there any special consideration or will any pump work well under these conditions?

    Thanks!

    What are you getting the water from, how far are you moving it vertically and horizontally through what size pipe and how much water do you need in gallons per minute?

    In addition to Bob's data request:

    1) How many Gallons per Day (GPD)? Don't know. How many homes do you want to supply from the reservoir? Rural or Urban?

    2) What other conditions did yuo have in mind besides being a pressurized system?

    3) Is there grid power at your location or do you depend on generator power?

    Thanks for the replies.

    No Grid power.

    I want to be able to pump about 2000 gallon in 3 hours. Total lift of about 70 ft.

    The main reason I am asking about this is to find out if a pump works differently if it is not under real pressure. The pump will just be pushing the water up to 70ft until a float switch trips with no back pressure.

    With a 70 foot lift, you will need to push the water up, not pull it up, unless you want to go with a deep well setup. And if so, you won't get that much water. A submersible would be the best choice. A 1/2hp 12 gallon per minute would work great.

    Thanks for the advice.

    Since most pumps are desigened to be in a system with a pressure tank, is the fact that the pump will not operate under pressure an issue at all? Could this be a good thing?

    There are more ways than one to operate a pump. Pressure switch, float switch or just manually turning it on and off. The pump can make plenty of pressure, but it is not important that it does.
