These double diaphragm pumps offer unrivaled advantages compared to other pumping technologies, making them the clear-cut favorite for many of the world’s most challenging fluid transfer and solids handling applications. AODD pumps are known for their simplicity and ability to reliably and safely transfer industrial liquids, solid laden fluids and slurries.
In this blog, we’ll discuss the key benefits of these double diaphragm pumps and why they’re so prominently used in so many different types of industries.
AODD pumps are versatile and reliable pumps that are used for applications in various industries. Some common applications of AODD pumps include chemical processing, wastewater treatment, mining dewatering, paint and ink production, and transfer of food products. Their self-priming ability and ability to run dry make them a popular choice in many industrial settings.
Markets and applications where diaphragm pumps are often used:
AODD pumps can run dry for an extended period of time without damaging the pump or its components. Other types of positive displacement pumps may be damaged by running dry, which shortens their service life and increases maintenance hours and cost.
AODD pumps require no electricity and can be used in enclosed spaces or underground, which means they can operate safely and reliably in explosive environments when equipped with the proper provisions.
AODD pumps can be completely submerged and not have their performance affected if:
AODD pumps can come with a wide range of certifications to meet the needs of users across the globe. Some common certifications include:
AODD pumps don’t use or require expensive mechanical seals to operate, which helps prevent leaks and additional costs in replacing seals and packings.
AODD pumps provide a wide range of flows without costly, sophisticated controls. Standard 1:1 ratio AODD pumps can operate with pneumatic pressures up to 125 psi (8.6 bar).
Other ratios AODD pumps, such as a 2:1 high-pressure unit, can produce pressures up to 250 psi (16.5 bar) when operating at 125 psi (8.6 bar). High-pressure units are occasionally used in applications requiring greater force depending upon the need (e.g., injecting into a pressurized line, viscous fluids or pumping further distances).
Compared to other technologies, the initial costs of AODD pumps are considerably less expensive as they don’t require expensive motors, controls or expert installation.
Many other pumping technologies require special controls or circulation loops that allow the pump to “deadhead”. AODD pumps are a great option for applications that are intermittent and require frequent deadheading because of on/off situations.
AODD pumps are gentle on the product being pumped and will not separate or create frothing, which is critical when pumping products that can be altered or ruined if sheared.
Double diaphragm pumps can be manufactured with many different materials, sizes and certifications. Thus enabling AODD pumps to be one of the most widely used pumps in the world.
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).
AODD pumps simply need air supply to power the pump. The pump can be controlled with a valve on the fluid discharge or by controlling the air coming into the pump. Accessories like filter regulators and air regulators are reasonably priced and easy to add to the pump.
Dangerous Chemicals Handling: Pump dangerous chemicals without worrying about chemical compatibility or other possible safety issues.
Solids Handling: Fluid containing solids can be pumped without clogging and/or stopping, which means less costly production downtime and less maintenance labor and costs.
Start/Stop Challenges: Gain the ability to start and stop automatically based upon open and closed lines downstream from the pump, especially when:
Fluids Handling: Handle thicker or sensitive fluids without shearing or damaging the product.
Temperatures: Don't worry about temperature. These pumps handle a wide range of temperatures and will perform smoothly whether you have an outdoor application in Northern Alberta or an indoor manufacturing application where temperatures exceed 300 degrees.
Run Dry: AODD pumps can run dry when a well, tank or fluid supply runs dry; this capability is especially helpful in remote locations where immediate detection may not be possible.
AODD pumps can be configured to meet an extremely wide range of applications. While other pumping technologies will be able to handle some of your needs, they may not be able to handle all of them.
AODD pumps are the chameleons of pumping technology. And because of their relatively low purchase and maintenance costs—as well as their superior all-around performance and capabilities—they’re one of the most widely used pumps in the world. Whether your application requires low or high flow, harsh or gentle performance, you can count on air operated double diaphragm pumps.
