City of Chicago Deep Water Pump Reliability Improvements and Energy Savings Project

This split-case double suction pump, driven by a 6000 HP motor, installed in a 350 feet tunnel, consumes 2.7 million dollars on energy alone a year! Each percentage point of efficiency improvement is equivalent to $30,000 yearly savings. Over the years, operating point changed, and the pump ended up operating at approximately 12% away from the optimum efficiency regime.
