Mine has quite a bit of friction just to turn it alone, which is annoying. I have been using it to flood my ice rink on my pond using a stout 1/2 18V drill to drive it. I pump up about 3' and then just out the 2 outlet to flood a 1/4 acre. I'm guessing its close to 50gpm, but I've never measured. I do overspeed it to prime it, but it doesn't seem to matter.

See other reviews...I was using the garden hose adapter with this pump to pump out a spring house, from higher elevation to lower elevation (that is, downhill). It wouldn't prime...period. I took off the adapter and filled it directly from a bucket to get it fully primed, put on the adapter/hose again, and it would only pump for about 2 cranks, then lose prime again. Also, it isn't really portable...very difficult to hold it and try and crank without it being screwed down onto some sort of permanent base. Waste of money...

I followed directions and had no luck pumping water from my spring. The couple of times it primed it was too hard to crank, then you would lose prime. I tried half a day to get it to work with no luck.

Purchased this item as a back-up/ emergency transfer pump to move water. Followed instructions exactly and used 2 ABS on the inlet and outlet as well as attempting to lift water approximately 3 feet and transfer to a holding area with a run of about 2 feet. Tried both hand cranking and with power drill. Neither worked. hand cranked for several minutes and nothing happened. Used power drill below 200RPM and still nothing. I would NOT recommend this pump to someone.
