Air Operated Double Diaphragm Pumps Highlights
Diaphragm pumps deliver several key advantages compared to other types of industrial pumps. Discover the benefits for yourself!
Self-Priming
AODD pumps can start without liquid and can handle thick, viscous fluids. They are versatile for many uses, from transferring abrasive slurries to pumping thick liquids. Self-priming saves time and ensures reliable operation in challenging conditions. AODD pumps perform consistently, even when installed above the fluid level or used in applications with frequent start-stop cycles.
Submersible
AODD pumps can be submerged in liquid, offering flexibility in installation. The pump operates efficiently when the exhaust line is above the liquid level. This setup is great for work with dangerous or unstable fluids. It reduces the chance of leaks and exposure. Submerged operation saves space and ensures consistent performance, even in fluctuating liquid levels.
Variable Flow Rate and Discharge Pressure
Acting on the air inlet lets you control the pump easily, so you can adapt it to changing needs without complex adjustments. It provides efficient, responsive operation, ensuring your system runs smoothly across a wide range of conditions.
Shear Sensitive Fluids
AODD pumps are ideal for handling shear-sensitive fluids. Other pumps can damage delicate materials, AODD pump’s smooth movement preserves the integrity of your fluids. This makes them ideal for use in food, pharmaceutical and cosmetic industries.
Discover the various applications of AODD pumps.
Dead-Head Capability
A key feature of AODD pumps is their inherent dead-head capability. Since the discharge pressure can never exceed the compressed air pressure, the pump can handle a closed discharge line without incurring damage or wear.
When the discharge line is blocked, the pump will simply slow down and eventually stop, all without risking harm to the pump components.
This automatic protection makes AODD pumps a reliable and low-maintenance choice for applications where flow interruptions or dead-head conditions might occur.
Handles a Wide Variety of Fluids with High Solids Content
AODD pumps can handle many types of fluid with high solid content. These pumps can move liquids with lots of solids particules. This design makes AODD pumps ideal for abrasive and slurry applications. AODD pumps work well with thick sludges, pastes and slurries. They are reliable and long-lasting.
Portable and simple installation
AODD pumps are portable and easy to install. They can be quickly transported and set up with minimal effort. Simply connect the air and liquid lines, and the pump is ready to go. There’s no need for complex controls or setup procedures, making AODD pumps convenient and efficient.
Intrinsically Safe Operation
AODD pumps use compressed air, so they are safe to use in dangerous places. There are no electrics, so they are ideal for use in explosive or flammable atmospheres. They work by air pressure, so they are reliable and safe.
Note that some diaphragm pumps are operated based on electrical motor for very specific type of operation as high precision dosing.
Able to Run Dry
Unlike most pump types, AODD pumps can run without fluid for relatively longer periods without risk of damage. This makes them useful for filling and priming, where the pump might run dry for a short time.
