[VERSATILE USE]~The diaphragm pump with convenient operating are widely used in various industries, such as petroleum, metallurgy, mining, coating material, printing, paper making, water treatment, automotive etc.
An air-operated double diaphragm pump (positive displacement pump or reciprocating pump) may be simple in design but that doesn’t stop it from operating across challenging environments. These mechanical pumps are appropriate for on-off cycling, continuous, and on-demand intermittent requirements.
Air-operated double diaphragm pumps (AODD pumps) are positive displacement pumps with two pumping chambers. Flexible diaphragms alternatively fill and discharge the two chambers. Air chambers on the other side alternatively fill and vent compressed air supply to create a pumping action.
AODD pumps are used in transfer applications and can handle a wide range of feeds, including slurries, sludge, and shear-sensitive and abrasive fluids. The pumps are reliable, robust, and easy to maintain. That said, they can be noisy, limited to low-pressure applications, and prone to icing.
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.
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.
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.
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.
The efficiency of the AODD pump depends on the compressed air supply. The pressure should be either equal to or higher than the pumped fluid. This makes the pumps suitable for low-pressure applications.
The pump speed depends on the supply of air and fluid. An increase in the compressed air pressure or reduction in the fluid pressure can increase the pumping speed. Additional flow and pressure control may be needed to maintain a constant flow.
The AODD pump draws power and control from an air distribution system which is relatively cheap, simple, and easy to maintain. However, some applications may need to filter expelled air to capture contaminants.
Poorly designed AODD pumps can constantly vent air, causing icing problems. You can minimize this by avoiding constrictions, reducing the humidity and pressure of compressed air, or installing a heater.
The cyclic action of the diaphragms creates a pulsating discharge. The fluid accelerates during the compression and slows down during suction. You can use the pulsation dampeners in discharge piping to reduce vibrations, loosened connections, and leakage.
AODD pumps can be noisy because of the vibrations and the constant venting of the air valves. You can reduce this noise by fitting a muffler on the air vent line.
Air-operated double diaphragm pumps function by displacing fluid from one of the two liquid chambers on each stroke. AODD pumps require a certain amount of pressure and air volume to deliver the fluid.
The two diaphragms are connected through a linked shaft, two inlet valve balls, and two outlet valve balls. The diaphragm acts as a membrane for separating liquid and compressed air supply.
Driving the diaphragms with compressed air pressure instead of the shaft balances the load and removes the mechanical stress. This allows the valve balls to open and close on the valve seats and direct the liquid flow.
The compressed air in an AODD pump enters an air motor. The air motor directs the air to push a diaphragm, pushing the liquid out. Another diaphragm attached to the first one is pulled, creating a cavity on the other side, refilling the second liquid chamber.
On the top and bottom of the two diaphragms are one-way valves (ball valves or flap valves). When a cavity closes, it pushes the liquid up and out. On the other side, it opens another cavity to suck the liquid inside. This can happen at up to 400 cycles per minute.
The outer fluid chamber is a part of the pump"s fluid path. It is sealed and attached to the discharge and suction manifolds by the seats. It is also sealed with the diaphragm"s bead between the air chamber. It creates an empty space for the reciprocating diaphragms to draw fluid in and push it out on each side to start pumping.
Diaphragms act as a barrier between the fluid side and the air side of the pump. They maintain a seal at the center of the diaphragm hole by tightening the inner and outer plates to the main shaft. The outer circumference is also sealed.
The plates work in combination with the diaphragms to isolate the fluids from the air. The plates are fastened to the diaphragm rod by threading, to compress the diaphragms and create an air-tight and fluid-tight seal.
The inner chamber holds the seal with the diaphragm when compressed air enters alternatingly. This pressurizes the rear of the diaphragms, which in turn puts pressure on the fluid.
The center block guides the main shaft with seals and bushings. The pilot shaft delivers alternating pressure on the air valve to shift the main valve spool, creating a reciprocating action within the pump.
The air exhaust muffler reduces the sound of the air from the pump. You can remove the muffler and port the exhaust. This allows you to submerge the pump or release the air to any other safer place.
Use heavy-weight valve balls while pumping viscous fluids. It will allow them to cut through the liquid and seat faster under gravity. This makes pumping with thick fluids efficient.
If you are pumping abrasive fluids, use abrasive-resistant valve seats. For example, stainless steel valve seats are suitable for abrasive ceramic slips. Polyvinylidene fluoride (PVDF) is more resistant than polypropylene in plastic pumps.
The fluid you pump will come in contact with both the wet side and air side of the unit. This can lead to chemical spills and fumes in the pump. Therefore, the air-side must have the necessary chemical compatibility.
During the suction cycle, compressed air fills the left inner chamber. This causes the opposite diaphragm to create suction and lift the lower valve ball to pull in the liquid. Simultaneously, the left fluid chamber undergoes the discharge cycle.
Although AODD pump solutions are easy to understand, it makes sense to know the specific components before selecting one. They can handle a wide range of chemicals, viscosities, and flow rates, and are applicable in many industries. Be sure to select pumps with maximum flow rates and minimum pulsation and air consumption.
Adler Tank Rentals offers air-operated diaphragm pumps from 2" to 3" for general fluid transfer. We offer 24/7 service, expert assistance, and transportation. The pumps meet stringent industry standards and undergo extensive testing.
AODD pumps have a simple and reliable technology with two air chambers and good suction lift characteristics. One of the main uses of this pump is that it can work with large solids without internal damage.

No matter what new developments occur in the world of diaphragm pumps, there are certain questions that never change. Here, we’ll resolve ten of the most frequently asked questions about air operated diaphragm pumps.
Fluid: The type and composition of the fluid you plan to pump is the most important factor when choosing a pump. In order to avoid wear and tear or corrosion, determine the fluid’s chemical makeup and consistency. Is it a clean fluid or slurry (semiliquid mixture)?
Viscosity: Fluid viscosity is an important factor in to the pump selection process. Robust pumping equipment is needed to move highly viscous fluids. To provide some perspective, at All-Flo, nine out of ten customers are pumping fluid less viscous than motor oil.
Flow rate: In order to select the appropriate pump, it’s important to determine the flow rate, measured in gallons per minute (GPM)—or in simpler terms, the existing pump size (diameter). Usually if you desire a higher flow rate, you’ll need both a larger pump and larger pipe size.
Diaphragm pumps are capable of pumping high viscosity fluids from adhesives and gear oils to hand lotions, surfactants and resins. The rule of thumb: If it pours, it pumps. Use large suction lines when pumping viscous fluids, in some cases up to three times the size of the pump ports. The pump should also be positioned close to, or even below, the fluid level. Higher viscosity fluids cause the pump to stroke more slowly; adjusting the air control valve on the pump to slow the air flow will keep the pump from stroking too fast.
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.
A common follow up to this question is, “Do plastic pumps always leak?” The answer is no; however, they should be regularly inspected and retightened more frequently than a metal or stainless pump. Frequency of tightening depends on the application; pressure, hours in service and fluid temperature will all affect the flow of plastic. Remember, plastic materials flow when compressed. Tightening the fasteners on your plastic diaphragm pump should be a part of any preventative maintenance program, based on the pump’s service duty.
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: air operated diaphragm pumps 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.
Air quality:Since air operated diaphragm pumps depend on air to operate, air quality and air moisture are critical to maintaining your pump’s health. Regularly check the air filter, which can become dirty and clogged with poor air quality. Moisture in the air should also be monitored to ensure proper pump flow.
Inlets/Outlets:Consistently inspect your pump’s inlet/outlet, also known as suction side/discharge side. It is common for rocks or other debris material to build up and clog pump flow.
Torque settings:Particularly with plastic diaphragm pumps, you should regularly check the torque of the pump’s bolts. Plastic components can compress over time.
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.
There is only one firm warning when regulating flow: Never restrict your pump’s fluid suction lines. Restricting fluid lines causes your diaphragm to fail and begin running in a state of cavitation, causing parts to wear rapidly and creating vacuum-void bubbles in the fluid being pumped.
Sometimes. The key factor when considering a different brand of diaphragm pump is your existing footprint. Several major manufacturers, including All-Flo, produce nearly every diaphragm pump specifically to drop-in ready specifications. 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.
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.
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.
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.
The cost to run a diaphragm pump can often significantly surpass the cost of the pump itself. Because of this, a great deal of time and research is spent on maximizing pump efficiency, and significant strides are being made to reduce the cost of operation.
Across a range of industries, pump users demand equipment that works as reliably as it does efficiently. And 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/freeze pumps that provide the high quality, trouble-free, continuous output—even under the toughest conditions.

Using an Air Operated Double Diaphragm Pump (AODD) is beneficial in many ways. This article will explain these benefits, particularly highlighting the superb effectiveness of the AODD pumps in specific applications while identifying the centrifugal pump"s shortcomings. AODD pumps can handle the types of applications that centrifugal pumps do not support due to their design, such as fluids containing abrasives, solid-laden liquids, and viscous fluids.
AODD pumps can also handle applications fatal to most centrifugal pumps, such as dry-running, self-priming, and seal-less. Further, AODDs support deadheading the discharge or starving the suction with no damage to the pump. AODD pumps" mobility and portability also give them the upper hand when compared to centrifugal pumps.
API Oil and Gas: upstream market for cellar sump and mud transfer applications; flap valve design allows passage of larger solids, ideal for abrasive slurries, suspended or non-suspended solids, and line-size solids.
In a centrifugal pump, any abrasive fluid will damage the mechanical seals, sleeves, and shaft. These damages require expensive pump repairs. It is necessary to use costly and specialized seal flush plans for even the slightest abrasives in centrifugal pumps. Conversely, AODDs can handle these abrasive fluids because they are designed with large openings, flow paths, and are fitted with diaphragm and check valve materials specifically designed to handle such liquids.
Solids in any centrifugal pump will be catastrophic. Damage to the impeller and other internal rotating parts will occur along with the possibility of burning up the motor. That damage is avoided with AODDs because of their design to pass solids. 3/8"-size solids pass through the pump due to ball valve technology. Likewise, 3"-line size solids travel through the pump thanks to flap valve technology. Shear-sensitive products like live fish and eggs utilize flap valve pumps to transfer without harm to the products.
Centrifugal pumps are generally limited to viscosities of 2900 SSU, whereas AODDs can handle well over 100,000 SSU, making them an ideal option for moving these viscous materials. AODDs are very effective for wastewater, sludges, and slurries with changing viscosities. Thicker consistent fluids such as glues and pastes can be moved effectively through these pumps also.
No centrifugal pump can run dry for very long. Most of the time, in less than a minute of a dry-run condition, a centrifugal pump will typically seize up, completely ruining the mechanical seal. This will also cause the motor to overload or burn up. AODDs can run completely dry without seizing, meaning you will not lose a pump and motor.
It is important to understand that operating a centrifugal pump dry leads to tremendous heat generation inside the pump, which leads to impeller damage and eventual failure. Compared to centrifugal pumps, AODDs are self-priming, seal-less, and considered leak-free. They are very effective at emptying sumps or lifting liquids from underground; they do not require any special items or features to achieve this. A centrifugal pump would require a special priming chamber and could only work in a self-priming application if it had no other use.
Closing a discharge valve on a centrifugal pump will cause failure to both the pump and motor and possibly could cause detrimental damage to many upstream system components. AODDs can withstand a closed discharge or deadheading with absolutely no damage to any internal item or its source of power: the air compressor. Additionally, a deadheaded AODD will not use any energy, meaning the pump will not experience wear, nor will organizations need to spend money on compressed air.
Almost every centrifugal pump has a specific design for certain application parameters that define the motor horsepower, impeller diameters, seals, and flush plans. Also, centrifugal pumps include a permanent base-mounted location for the unit with hard piped suction and discharge connections. It is required to use expensive variable speed drives for changes in application flows and pressures. These dedicated systems often require expensive conversions to be utilized for anything other than its original, intended purpose. Mobility Is an Added Advantage to the AODD
Here is a picture of an AODD on a pump cart that includes a strainer, valving, and gauges. This AODD was used for loading latex material from various tanks and the manufacturer’s site to the trucks to transport to the next process.
AODDs offer flexibility over centrifugal pumps due to their ease of portability and multiple different use cases. They can be cart-mounted and portable to work in numerous areas of any plant or outdoor job site and can be used to pump various fluids. This flexibility allows the AODD to act as a backup pump for units in repair, units in use, or as a utility clean-up pump on-demand. AODDs can also function as a sump pump for dewatering. These pumps offer variable flow rates by controlling air line pressure and can utilize control valves, float switches, and even batch controllers to be part of an automized system.
It is true that AODDs are not very energy efficient and can be noisy. They do vibrate and create pulses in the discharge that can be harmful to many downstream components. Although, the flow smooth out with pulsation dampeners. Despite these potential issues, AODD pumps are robust, reliable, easy to maintain, and relatively low cost when compared to centrifugal pumps. AODDs tend to be durable workhorse devices and work for various transfer applications in a wide variety of industries.

An air operated double diaphragm pump is a very reliable pump type and certainly very easy to operate and maintain. Nevertheless, there are a number of things that allow you to “kill” your pump.
Dry running an AODD will not have an immediate negative effect on your pump, but an AODD who runs dry will speed up. This will not only cause a bigger air consumption but the diaphragms will make a lot of strokes and will come to the end of their elasticity much quicker and will fail. To prevent this you can use a “Flow Stop Valve” in the air supply to your pump. This valve will detect the bigger air consumption and will close down the air supply to the pump.
Air moisture and air quality are of utmost importance high moist or bad quality of the air can cause icing or clogging of the air valve or muffler; the moisture will condense in the air exhaust because of temperature drop from high to low pressure and will cause clogging the muffler. Also waste collected over time can cause clogging. Use clean, dry, filtered air to avoid clogging/icing of the muffler. Check the muffler on dirt on a regular basis and check the quality of the air you use to operate the pump. If the plant air is from low quality the use of an ”Anti-Ice Muffler” and Installing an air filter in the compressed air line before the pump will also help you to run the pump error free.
An incorrect diaphragm selection can cause rupture of the diaphragm and many other problems to the pump. The lifetime of diaphragms depends strongly on the material the diaphragm is made of. Always check if the material of your diaphragm is resistant against the liquid you are pumping. PTFE diaphragms can be used on almost all chemical applications, but doesn’t have the best mechanical strength so will be prone to wear in abrasive applications. Diaphragms made of molded PTFE on a rubber layer will give a better result on this kind of applications. If not sure, ask a specialist which material to use as diaphragm will give you the best cost/lifetime combination for your application.
If you run an AODD fast on abrasive applications, the valve seats and balls will run out very quickly. Also the life-time of your diaphragms will be reduced. On those applications you will need to use a bigger pump running slower.
Not efficient AODD pumps will have a bigger air consumption and will need more time to do the job. This will generate more maintenance not only at the pump, but also on the compressed air installation. (compressor, dryer, supply pipes,…)
Rapid acting air valves & an innovative flow pattern inside the pump are resulting in a higher flow rate, lower air consumption and less maintenance of a pump and compressed air installation. Verder offers those features with the Verderair double diaphragm pumps. This results in an increased productivity, reducing operational cost and improve working environment.
