Circulation pump

The circulation pump arranged horizontally is a single-stage and water-cooled centrifugal pump with mechanical seal. The mass flow of the pump during operation of the electrical heater amounts to about 11 kg/s. It is designed for a maximum pressure of 9.8 MPa and a maximum temperature of 308 °C.

For compensation of the pressure drop at the electrical heater entry, and for the generation of a consistent flow through all 24 heating pipes, a pressure increase of 1.55 MPa through the pump is necessary. The maximum discharge head of the pump amounts to 207.5 m.
