Peristaltic Pump Requirements for an ED Plant

For my master thesis I am working on a simulation in Matlab/Simulink for an electrodialysis unit powered by a PV-system for brackish water. I have been reading about the design of an ED system, but what are the most common requirements of peristaltic pumps? Can anyone suggest where I can find this information?  I am trying to make the simulation as simple as possible, I would not like to simulate all transport phenomena in the ED process since it would be out of the thesis scope.
