Description
Two centrifugal pumps are required to pump the electrolyte into the cells. In addition, in each electrolyte circuit, two pumps are arranged redundantly. For the design of the pump it is assumed that the effective volume flow is 200 m3/h. The required size and mass of the pump can be derived from the data given in the technical data sheets from commercial providers of centrifugal pumps. Here, the flow rate is used as the basis for further calculations. As a result, the weight per pump is calculated to be 145 kg. Since there is no further information on the exact composition of the various materials for the production of the centrifugal pump, a reference process from ecoinvent is used for 408 assistance (pump production, 40 W). The required masses of the raw materials are adapted correspondingly, since the modeled VRFB pumps have a higher power.
