How do I know what Air Operated Diaphragm pump to buy?
You must match your requirements to the pump’s characteristics. Here are the five important considerations for choosing an AOD pump:
Fluid – The makeup of your process fluid is crucial to the choice of pump. Does it have special chemical or 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.
What are the key factors for diaphragm pump maintenance?
The good news is that AOD pumps are comparatively easy to maintain. Importantly, and like every other pump, a regularly scheduled maintenance is crucial. You want to monitor things over time, to prevent mishaps before they happen. There are essentially 4 main things to keep an eye on during the life of an AOD pump.
First, the quality of the air used to operate the pump. Air can come in many different qualities with various amounts of water. Impurities are removed by an in-line air-filter. Making sure that this is operating and doesn’t become clogged with debris from poor quality air is important to prevent these particles from reaching the pump and causing premature wear on the pump diaphragms.
Second, examine the pump’s elastomers (diaphragms) routinely for signs of wear – replace these if necessary.
Third, make sure you frequently check the fluid inlet and outlet of your pump. If either of these becomes clogged, it can lead to premature failure of the pump.
Last, especially with pumps constructed of plastic, which can change shape over time, becoming compressed, make sure that you check the torque settings of the pump’s bolts.
