What water pumps are used by ten tractors to irrigate the ground?

Weld the bracket on the front and install a three-inch self-priming pump, made of aluminum, which cost me 200 yuan. I was sucking water by the river. The suction distance was 3-4 meters vertically. I used a fire hose for the lift. The river slope was very funny, 8-9 meters high. Go to the end of the field and turn the 2.5-inch white water pipe for 100 meters, and then connect the 100-meter fog pipe. Medium throttle or a little smaller, the water volume is sufficient.
