摘要：

This work was carried out to evaluate the performance of a centrifugal pump operating with wastewater from coffee process. Under laboratory conditions, it was determined the hydraulic characteristics (manometric height, engine power and efficiency) for a centrifugal pump, operating with clear water and coffee process wastewater. The results have show that manometric height and efficiency was smaller and the engine power was higher when the coffee process wastewater was used in comparison with results obtained for clean water. The smaller the concentration of that coffee wastewater produced the better the performance of the pump in comparison with the performance obtained with original concentration of the coffee wastewater.
