I would like to circulate the water within an aquarium that contains around 30l water with a circulation pump and an active chiller that contains R134a cooling fluid. New water shall be sucked with a peristaltic pump that can build up a pressure of up to 15bar. I was thinking of mixing the chiller cycle with the peristaltic pump but I think this could be a faulty design as the peristaltic pump will pump into both direction of the chiller circle. Please see a schematic below. How would you realize the piping?
Further information as requested by @mart
- Flow rate is around 100-200l/h from the peristaltic pump and 1200-1500l/h from the circular pump.
- I don't know the head loss of the chiller, I contacted the manufacturer. It is a Titan600 from aquamedic.
