HG - The intelligent pump series For any plant or system to be truly efficient, its individual components must be designed for efficiency too. Boiler feed pumps in power stations consume typically 3 - 5% of their unit's power output. Consequently, any improvement in their efficiency and energy balance will directly enhance the economic efficiency of the entire plant. • • •
