1. Selection (1) the flow of the pump should be within the required time to complete the required irrigation area or drainage area; pump flow should be less than the continuous water supply to ensure that the pump continuous operation. (2) The suction of the pump must be greater than the static water level of the water source. The type of the pump should be consistent with that of the water source. This is easy to install and transport
