Turbine pump selection for agricultural applications in Saudi Arabia

الملخص EN

A thorough hydraulic analysis is used to evaluate turbine pump selection for agricultural purposes in Al-Qassim Province of Saudi Arabia.

In this study, 18 real-world cases are considered.

Com- plexity of irrigation systems for these cases ranges from a single tur- bine pump supplying a single sprinkler system to multiple turbine pumps supplying a complex irrigation network.

For each case, the ex- isting pump in operation is evaluated; then, competitive pumps are checked for suitability for the same application.

Since operational costs dominate other factors for pump selection, this study considers the pump that requires less input power as a better selection for a giv- en application.

In most cases, it is found that the pump in operation is not the best pump.

In addition, in most of these cases, the pump driver is found to have excessive power more than the minimum required in-put power to operate the pump.
