How Polymeric Coatings Work

and distribution system, approximately 70 to 90 percent of the energy used is for pumping. With the rising cost of electricity, more municipalities are searching for technologies to improve operational efficiency. One method for improving the efficiency of pumps is to line the pumps with a polymeric coating system. Polymeric systems have been shown to provide increased flow at the desired pressure, increased pressure at the designed flow, increased efficiency over a wide range of flow rates and reduced power consumption. In many cases, new water pumps can also benefit from an efficiency coating for performance and protective purposes, even though pumps are normally not expected to outperform the original efficiency status certified by pump OEMs. During the lifetime of a centrifugal pump, the cost of the energy it consumes is far in excess of the capital cost of the equipment itself. Therefore, efficient operation of the pump is essential to optimize operational costs since any increase in fluid efficiency gives immediate savings in power consumption. According to case studies, the typical payback period for a polymeric coating, based on reduced power consumption, can range from a few months to two years depending on the size of pump.
