Test section pump

The test section pump circulates the water from the steam drum through the test sections.

The rotation speed of the pump is controlled by a frequency converter. By means of this device, the volume flows through the TS can be adjusted in a wide operational range up to 200 m³/h in connection with a pressure increase up to 0.8 MPa.

The pump is constructively designed as a horizontal, single-stage and water-cooled centrifugal pump with mechanical seal. It is designed for a maximum pressure of 10 MPa and a maximum temperature of 300 °C. For a safe operation of the pump, it is necessary that the seal is cooled by water. To protect the pump against superheating, the frequency converter limits the minimum rotation speed to 1500 1/min.

Moreover, the pump is equipped with a bypass line, which opens at a flow rate of approx. 6.25 kg/s.
