Situation

Each pump was continuously drawing 136 kW, which was more than the motor’s rated power and pump brake horsepower at the design point.

The Solution

  • NTPC accepted the recommendations from MagnaDrive’s partner in India, AVJ Engineering, and placed an order for a MagnaDrive 17.0S FGC E-Max.

The Results

  • MagnaDrive estimated 10 to 15% in energy reduction and an operating capacity for the pumps closer to the design condition.
  • After the E-Max coupling was installed, energy use was reduced from 135.61 KW down to 113.54 KW, a savings of 22 KW (16% savings).
  • Vibration levels were decreased by 73%
