Why is my diaphragm pump not working?
Blocked or worn air valve or muffler: Damage, corrosion or dirt on the air valve will affect the function of your Diaphragm Pump. Additionally, if the muffler is blocked, the pump cannot expel air effectively meaning the pump won’t operate efficiently.
How does an ARO diaphragm pump work?
How do air operated diaphragm pumps work? AODD pumps utilize dual flexible diaphragms mounted to a shared shaft which moves back and forth repeatedly in strokes to pump fluids into and out of the pump’s fluid chamber. This movement creates a vacuum, which intakes fluid through an inlet port.
What is an ARO pump?
ARO Pro Series air operated diaphragm pumps are ideal for general industrial and OEM installation applications. They reliably pump fluids ranging from clean, light viscosity to corrosive and abrasive, medium viscosity. Plus, they can transfer large particles without damage.
How do I test my diaphragm pump?
Troubleshooting a Diaphragm Pump
- Check the inlet air line size and pressure.
- Inspect for muffler icing and restrictions.
- Inspect sealing surfaces for leakage.
- Ensure proper tubing and piping size.
- Slow the pump down to prime.
- Clear any fluid line restrictions.
Does a diaphragm pump need to be primed?
Diaphragm Pumps Are Self-Priming Unlike some other pumping technologies, AODD pumps are self-priming and don’t require positive inlet pressure to prime (flooded or needing a dry suction lift).
What is Ingersoll Rand ARO?

What causes a diaphragm pump to stall?
Too much back pressure can cause the pump to stall if the fluid pressure overcomes the air pressure to the pump. To control the performance (flow and pressure) of an AODD, it is important to have an air regulator assembly installed to control the incoming air pressure (see Figure 1, C).
Can you run a diaphragm pump dry?
Double Diaphragm Pumps Can Run Dry Without Damaging the Pump or System. AODD pumps can run dry for an extended period of time without damaging the pump or its components. It’s very common for pumps to run dry.

How do you test a diaphragm pump?
Connect a vacuum gauge to the pump inlet – turn the air on to the pump – check the vacuum reading is as per the dry lift on the manufacturer’s literature. Turn off the air to stop the pump.
