The features and benefits of air-operated double diaphragm pumps

The simple design of AODD pumps makes them easy to use. They don’t have any close-fit, sliding, or rotating parts and thus, require minimal assembly. Once you connect the AODD pump to a compressed air supply, they are ready to run.

AODD pumps can run dry without damaging the parts or destroying the motor. They don’t use any lubricants or oils making them free of clogging due to lack of lubrication. The pumps don’t require any cooling mechanism.
You can program the system to shut down once it has reached certain pressure without damaging the pump.

Air-operated diaphragm pumps are lightweight and portable, which makes them easy to use in diverse locations. They are easy to dismantle, repair, clean, and maintain.

You can use AODD pumps for diverse mediums such as water, effluent, harsh chemicals, naphtha, and animal entrails. They can handle water, 90% solids, and everything in between.

The pumps are customizable and can meet your application requirements, keeping costs to a minimum.

AODD pumps operate on the compressed air supply. They don’t require a power source or fuel to run. This eliminates any harmful exhaust, short circuits, and liquid spilling on live wires thus keeping the surroundings and workers safe.

They are fully sealed and you can submerge them in any liquid safely. The pumps are suitable for the food and beverage industry because they are not a contamination risk.

The pump comes in different sizes and flow rates. It can pump as slowly as 1-gallon per minute.

Double diaphragm pumps are easy to maintain. They don’t leak unless both the diaphragms fail. The internal ball valves provide a better seal and are less prone to wear than flap valves.

What are the main applications for Air Operator Double Diaphragm Pump pumps

Mining (Can operate in classified/hazardous areas)	Dewatering above and below ground sites and quarries Transferring abrasive slurries and sludge mixtures Dosing reagents Transferring solvents for separating minerals from ore Transferring fuels for vehicles and equipment
Coatings (Can pump low to very viscous solutions, and capable of low shear / gentle fluid transfer)	Transferring, dispensing and dosing paint, ink and dyes Feed pump for spray guns Flush/clean paint lines with solvents
Ceramics (Can operate with highly abrasive slurries)	Ceramic slips Day tank transfer Filling moulds Circulating ceramic slurry Waste water transfer
Chemical (Excellent chemical resistance with corrosive/ hazardous chemicals)	Loading and unloading tankers, totes and barrels Portable utility pump Batching/dosing chemicals
Electroplating and Anodizing	Replenishing chemicals in plating and metal finishing tanks Agitation of cleaning solutions Circulation of liquid to avoid sedimentation Filtration (when critical purification is required for high quality parts) Offloading corrosive, solid laden waste
Pulp and Paper	Printing inks Glues Kaolin clay Bulk transfer Resins Dispersions
Oil and Gas (Can operate in classified/hazardous areas)	Settling pond transfer Oils and glycol transfer Sumps Filter press Bulk transfer
Water / Waste Water Treatment	Transferring solid laden media Filter press Sumps Utility pump

What to do if an AODD pump will not prime

Check the application is within the pump’s capabilities. If your pump has a 3.6 m dry suction lift, but the application requires a 4.5 m dry suction lift, then the pump may not prime.

Check that all process pipework valves are open. A closed valve in the suction pipework will stop pump priming. A closed valve in delivery pipework can cause an "air lock" that can stop pump priming.
Check there are no leaks in the suction pipework. Any leaks can result in air getting into the pipework, displacing the product.

Verify that the suction pipework is not collapsing under the vacuum. Suction pipework should be of a reinforced material that maintains its diameter.inspect the pipework to make sure there are no kinks between the pump and the source of the product fluid.

Check that the suction pipework is the appropriate diameter and length for the application. Thick, viscous product requires larger diameter pipework and shorter runs between the source of the liquid and the pump.

When pumping with high-viscosity products, the best practice is to start the pump slowly. This allows the pump to prime. Once primed, speed up the pump to reach the most efficient pump operation.
Inspect any filters in the suction line and verify that they are not clogging.

Check for wear of internal pump components and replace as needed. These items include the divider seal, balls and seats.

FAQ

Q: Ow do you regulate the flow of a diaphragm pump?

A: 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 air line.
Open or close a valve on the fluid discharge.

Q: Can i replace one brand of diaphragm pump with another?

A: Sometimes. The key factor when considering a different brand of diaphragm pump is your existing footprint.this means that most of our pumps can be used in any existing footprint. If you are looking to make a switch, carefully consider your existing set up and ask your distributor to help identify a suitable alternative.

Q: What suction lift can i expect from a diaphragm pump?

A: 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 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.

Q: Can a diaphragm pump be submerged?

A: 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.

Q: How much does it cost to run a diaphragm pump?

A: As with all things related to diaphragm pumps, the cost to run it depends on several factors including pump size and hours in service. Another key factor is the brand of pump you choose and that product’s efficiency rating. To give you an idea, 2-inch (51-millimeter) diaphragm pumps range in price from $1400 to $6000 and can cost anywhere from $3000 to $11,000 per year to operate.

Q: What is the material used for the diaphragm in an air operated diaphragm pump?

A: These materials can be grouped into three primary families: rubber, thermoplastic elastomer(TPE) and polytetrafluoroethylene (PTFE). These primary materials are available in a variety of designs – each offering unique benefits depending on the application and the characteristics of the product being pumped.

Q: How do you control an air operated diaphragm pump?

A: To control the performance (flow and pressure) of an AODD pump, install an air pressure regulator assembly in the pump's air supply line to control the incoming air pressure. Installing the correct air line size with an air regulator will solve most AODD pump installation problems.

Q: What is the maximum pressure for an air operated diaphragm pump?

A: But what sort of air pressure range do diaphragm pumps typically use? Most air operated diaphragm pumps can handle air pressures up to 125 psi or 8.6 bar. Operating a diaphragm pump outside of these ranges can result in failure.

Q: What is the difference between single and double diaphragm pumps?

A: The main difference is that a double diaphragm type has two diaphragms that work in tandem to increase the pump's ability to move fluid. This allows the pump to reach higher pressures and flow rates than a single diaphragm pump. The pump displaces a fixed volume of liquid with each stroke of the piston.

Q: What are the parts of a double diaphragm pump?

A: The pumping unit in a diaphragm pump consists of: diaphragm, suction valve, pumping chamber and delivery valve.
