No matter what new developments occur in the world of diaphragm pumps, there are certain questions that never change. Here, we’ll resolve 9 of the most frequently asked questions about ARO diaphragm pumps in GA.

1. How do I know what type of air operated diaphragm pump to buy?
While this seems like a loaded question, there are only five things you need to know when selecting the right pump for your particular application.

1.Fluid: The type and composition of the fluid you plan to pump is the most important factor when choosing a pump.

2.Viscosity: Fluid viscosity is also an important factor – robust pumping equipment is needed to move highly-viscous fluids.

3.Flow rate:
In order to select the appropriate pump, it’s important to determine the flow rate, measured in gallons per minute (GPM) or the existing pump diameter.

4.Pressure: Determining the potential pressure conditions on the inlet and outlet of the pump will help establish the right equipment needed.

5.Temperature: The temperature of the fluid dictates the pump material best suited to a particular application.

2. What kind of fluid does a diaphragm pump transfer?
ARO diaphragm pumps in GA will move nearly any kind of fluid. They are capable of pumping high-viscosity fluids from adhesives and gear oils to hand lotions, surfactants, and resins. The rule of thumb is that if it pours, it pumps.

3. Are there specific considerations for plastic diaphragm pumps?
Plastic diaphragm pumps are best suited for applications involving chemicals like acids, caustics, and bleach. Some chemicals are not suitable for plastic pumps, such as styrene and certain resins like isocyanate and polyol.

4. What are the key factors for diaphragm pump maintenance?
In order to avoid expensive repairs and delays, and keep your production running smoothly, you should implement a regular pump maintenance schedule. The good news is that ARO diaphragm pumps in GA are very easy to clean and maintain, compared to other types of pumps with a lot of electrical components and parts.
Even better, in most cases, you’ll only need a wrench and a screwdriver to keep your pump in top working condition.

5. What kinds of facilities use diaphragm pumps?
Facilities of all sizes, and in a broad spectrum of industries, use air operated diaphragm pumps. These include petrochemical, metal fabrication, mining, water, construction, cleaning, food and beverage, and printing and ink.

6. How do you regulate the flow of a diaphragm pump?
You can increase or reduce air pressure (ensuring you are within the pump’s operating limits), increase or decrease the amount of air volume using a valve on the airline or open or close a valve on the fluid discharge. Never restrict your pump’s fluid suction lines as this can cause your diaphragm to fail and parts to wear rapidly.

7. What suction lift can I expect from a diaphragm pump?
Features like suction lift tend to vary widely from manufacturer to manufacturer and depend on factors like the size of the pump, fluid viscosity, and whether you’re looking for a wet or dry lift. A safe, average range would be between 8 to 15 feet (2.44 to 4.57 meters) depending on the pump’s elastomers.

8. Can a diaphragm pump be submerged?
Yes, a diaphragm pump can be submerged if the fluid is compatible with the pump housing and fasteners and if the exhaust is piped above the fluid level.

When your equipment performs with the versatility and durability that your application demands, you can keep things running smoothly. Air operated diaphragm pumps are rugged, lube-free, non-stall pumps that provide high quality, trouble-free, continuous output, even under the toughest conditions.
