Precision Irrigation Pump Selection Guide

Precision Irrigation Pump Selection Guide

Step 1: Understanding Core Parameters

Flow Rate: Water output per unit time, must meet the needs of the irrigated area and crops.

Head: The pump's ability to lift water up to the desired height and distance, including vertical height and pipe resistance.

Power: Energy consumption after matching flow rate and head; higher is not always better.

Step 2: Matching Farmland Needs

Calculate Required Flow Rate: Estimate based on crop type, area, and irrigation cycle.

Calculate Actual Head: Height difference from water source to irrigation point + pipe length loss (approximately 1 meter head loss for every 10 meters of horizontal pipe).

Allow a Margin: Add a 10-20% safety margin to the calculated results.

Step 3 Step 1: Choosing the Right Pump Type

Centrifugal Pump: Suitable for surface water sources, affordable.

Submersible Pump: Suitable for deep wells, easy to install.

Self-priming Pump: Suitable for pumps positioned above water level.

Key Recommendations:

Bring a farmland topography map and water source location map when purchasing a pump.

Prioritize energy-efficient products with high energy efficiency ratings.

Ensure the pump operates within its high-efficiency zone (check performance curves).

Maintain the pump regularly and clean the filter promptly.

Common Misconceptions:

Focusing solely on power output while neglecting flow rate and head matching.

Failure to calculate resistance losses from pipe bends, etc.

Choosing an oversized pump for "safety," resulting in wasted energy.

Precision irrigation begins with precise pump selection. Measure first, then calculate, and finally select the appropriate model to achieve a highly efficient and energy-saving irrigation system.
