Centrifugal Pump Efficiency Problems
One of the key challenges faced in the operation of centrifugal pumps is related to efficiency problems. Eddy losses play a significant role in reducing the overall efficiency of centrifugal pumps. These losses occur due to the formation of turbulent eddies within the pump, leading to energy dissipation and decreased performance.
