Sling Pumps

Sling pumps require flowing water for power. A sling pump is a cone-shaped pump that is attached to the bottom of a stream. Stream current spins propellers, driving water though plastic pipe to a point that is accessible to cattle. These are fairly expensive ($800 to $1,200), and you must have flowing water to drive the propellers. They are easy to set up, but there are limits to how high and now far water can be pumped.

Thank you in advance!
