This pump is purposely designed for pumping hot oil at 450°C, used for catalyst heating in a pilot plant. The pilot plant has been built in order to test a new process of extraction of hydrocarbons from garbage.
Even if this is a magnetic drive seal-less pump it has been equipped with an internal mechanical seal in order to keep separate the high temperature pump volute (450°C) and the magnetic coupling (maximum allowable temperature 315°C). Magnetic coupling is maintained cooled around 100°C , by using an external flushing compatible with the process fluid.
