Axial flow irrigation pump

Part of CIMMYT

Axial flow pumps (AFPs) are a climate-smart irrigation technology that delivers considerably more water while significantly reducing fuel energy use. AFPs are a reliable technology that lower the environmental footprint of surface water irrigation.

Problem

Costly and fuel inefficient irrigation practices

}

Solution

Axial flow pumps are affordable and fuel-efficient, delivering more water per drop of fuel consumed. The technology has been scaled in Bangladesh by replacing less efficient surface water irrigation pumps and encouraging irrigation service provision business models, while aligning with the private sector to import, manufacture, and durably sell axial flow pumps in the FtF zone.

Target Beneficiaries

Smallholder farmers, irrigation service providers, machinery dealers, machinery mechanics, agricultural machinery companies

Innovation Description

Comparing the hydraulic, energetic and economic performance of prototype axial compared to conventional pumps, AFP discharge is larger than centrifugal (CEN) pumps, but inversely related to increasing head. Discharge per unit of fuel was highest for AFPs (+51 and +21% at 1- and 2-m lifts), but declined with rising head until convergence with CEN pumps at 2.8m. High AFP discharge reduced irrigation time requirements. On average, AFPs can save between US$70 and 38 ha 1 season 1 for boro rice at 1- and 3-m heads, respectively, and between US$15 and 8, and 26 and 14 ha 1 season 1 for wheat and maize farmers.

The Team Behind the Innovation

The Cereal Systems Initiative for South Asia (CSISA) is led by the International Maize and Wheat Improvement Center (CIMMYT) and implemented by a team of scientists and change-makers with the International Food Policy Research Institute (IFPRI) and the International Rice Research Institute (IRRI). Operating across South Asia, CSISA works to increase the adoption of resource-conserving and climate-resilient technologies and improves farmers’ access to markets and enterprise development.
