Costa Rica is one of the countries with the highest level of agricultural development in Central America. The utilization of solar water pumps in agricultural irrigation is also increasing. A Costa Rican farmer purchased a DIFFUL solar pump to water the crops on the hillside. Due to the high lift required by the customer, we recommended the solar screw pump of the model 3DSS2.0-150-72-750. This solar pump features a high lift and a maximum lift of 150 meters.
