Energy Efficiency Improvement in Industrial Pumping Systems

The industrial sector accounts for a major chunk of power consumption in India, it is estimated to be approximately 36.5% of the total power produced. Process industries can be of different domains, but majority of them have a basic requirement of water pumping system. This pumping system accounts for 25-30% of power consumption in industries with basic requirement to fulfill by using pumped water for various applications like process requirements, cooling systems, heat exchange, steam production etc. Due to high power consumption in these motor driven pumps operating at poor efficiency due to wrong pump selection and deviation of operating point from optimum efficiency point led to major losses and there is a good scope of energy savings in such systems. A textile industry consumes huge amount of energy and water in processes like washing, bleaching, dyeing, scouring, finishing etc. The performance study of pumping system in one such textile unit is presented in this paper.
