You must match your requirements to the pump’s characteristics. Here are the five important considerations for choosing an AODD(air-operated double diaphragm) pump:
- Fluid –The makeup of your process fluid is crucial to the choice of pump. Does it have special chemicalor corrosive requirements? Is it clean or does it contain particles (slurry)?
- Viscosity – The viscosity of your process fluid is also important. More viscous fluids require more robust pumps to move them.
- Flow rate – You need to know how much liquid you need to move per unit time in order to choose both the correct size pump and the correct size of piping.
- Pressure – The pressure will also be a major factor, one that is intertwined with the flow rate, in choosing an appropriate pump. Refer to your pump’s “pump curve” graph to help determine the relationship between flow and pressure.
- Temperature – Your choice of pump necessarily need to depend on the temperature of the liquid being pumped.
