The increasing demand for clean water has led to a growing number of desalination plants. The thermal process involves evaporating and then condensing seawater, while the reverse osmosis (RO) process uses high-pressure pumps. Both require a large number of pumps and reliable mechanical seals.
According to EagleBurgmann, the high salt content of seawater or concentrated brine, the chemicals in the brine, and pressures of up to around 60 bar pose extremely high demands on pumps and seals. The design and materials of the seals therefore determine the reliability and safety of the system.
It is necessary to clearly identify the type of pump (feed pump, high-pressure pump, brine circulation pump), the pressure in the seal chamber, the content of sand and solid particles, as well as maintenance requirements.
