I'm very happy thank you
I got the water pump and overall, I am satisfied with it. The description is very relative (missing a graph with yield vs pressure, yield vs voltage). I make some measurements for you in order to know what you are buying: Water discharge at 24V (at the same level with 3 m 19 mm diameter tube): 27 l/min (1.6 m3/h) Water discharge at 12V (at the same level with 3 m 19 mm diameter tube): 14 l/min (0.84 m3/h) Water discharge at 24V (at the same level with 20 m 1/2" diameter tube): 12 l/min (7.2 m3/h) The pump works also with 6V, with a proportionately lower yield. It can also create higher pressure, but of course, this also results in a drastic decrease in yield (this is normal). Under realistic conditions, you don't get the values from the description (but this is always the case). Another issue is that the motor is not started in any position only after the manual starts. I opened the motor; I cleaned the insulation from the copper wire and it works well.
