Figure 23. AirLift Pump
Another option is the Peristaltic pump used in dialysis machines shown in the
Figure 24. This kind of pump is best suited for vicious fluid. In our case it is not a good idea since we are
going to pump. Advantages of this pump are: no hazards and low cost because only the plastic tube has
contact with the water. The pump has issues with the water flow and high maintenance. We are not
aware of any aquaponic system using this type of pump.
