Power plants are highly sensitive. To ensure that they produce electricity and heat at optimal levels, the amount of steam delivered to the turbines needs to be very precise. Feedwater pumps play a central role in achieving this. Their ceramic seals are placed under extreme chemical stress by the feedwater. However, by coating the ceramic rings with a new and extremely thin layer of microcrystalline and electrically conductive diamond, their durability can be vastly increased. Allowing them to last for 16,000 operational hours or even more – at least eight times longer than before.
