The pumps are the heart of any system that handles fluids - the second most common piece of machinery used in general industry. Pumps use mechanical forces to move fluids namely gases, liquids, or slurries from one location to another what is referred to as a hydraulic passage. The hydraulic passage is the trajectory followed by the fluid inside a pump, and it depends on the design of each pump. The transfer of fluids accounts for the largest single use of energy worldwide with millions of litres pumped from one location to another every second of everyday worldwide, it is therefore understandable that the rising cost of energy has lead to all energy intensive Industries such as Cement, Sugar, Steel, Textile, Fertilizer, Paper & Pulp, Refinery, Aluminium, Petrochemical etc., to look for solutions to improve operational efficiency of Pumps. A major problem is increased turbulence caused by the detrimental effects of erosion corrosion. This leads to rough and pitted surfaces which in turn, increase drag, therefore reducing the efficiency of the system. In fluid dynamics, water molecules on the pump surfaces are stationary. Discrete water molecules in the flow behave as separate entities creating vortices and cross-currents which result in energy losses in addition to those arising from skin friction, which still continues to be exerted next to the boundary layer, in a thin film known as the laminar sub-layer. The energy cost of a pump represents the largest portion of its lifetime costs - much more than the capital cost. In fact, operating costs can represent as much as 95% of the overall lifetime costs of the pump. Therefore, an improvement in energy efficiency will represent a significant reduction in lifetime costs. Deterioration in service can reduce efficiency, leading to as much as 10-15% extra energy consumption.
