The delivery distance of common agricultural water pumps varies with many factors, including pump type, power, head, pipe diameter, pipe material, topography, and system design. The following are the general water delivery distance ranges of some common agricultural water pumps for reference only:

1. Small manual/electric water pump: Usually suitable for irrigation and water lifting of small-scale farmland, and the water delivery distance is generally about tens of meters to one hundred meters.

2. Self-priming centrifugal pump: Generally, the distance that can deliver water is between tens of meters and more than one hundred meters, depending on the power and lift of the pump.

3. Axial flow pump: It is suitable for large-scale farmland, such as rice fields, and the water delivery distance may be between hundreds of meters and hundreds of meters.

4. Centrifugal pump: This is a common type of pump, which can usually send water over a distance of hundreds of meters to several thousand meters, depending on the model, power and head of the pump.

5. Diesel water pumps: As diesel water pumps usually have larger power and head, the distance that can deliver water may be farther, which may reach thousands of meters or even farther.

It should be emphasized that these values are general ranges, and the actual water delivery distance will be affected by the combined effects of the above factors. When selecting an agricultural water pump, system design and calculation should be carried out according to specific project requirements to ensure that the pump can meet the expected water delivery distance requirements and maintain efficient operation of the system. The best course of action is to consult a professional agricultural engineer or pump manufacturer for accurate advice for your particular situation.
