Antlia AODD (Air Operated Double Diaphragm) pumps are capable of transferring a wide range of viscous materials — including oils, lubricants, inks, adhesives, and other similar thick fluids. The ability to handle viscous materials depends on two key factors: the pump design and the diaphragm material selected for the application.
In general, AODD pumps are well-suited for handling viscous fluids because they can generate high levels of suction and discharge pressure. This makes it easier for the pump to move thicker, more viscous fluids through the system.
Additionally, AODD pumps have no close-fitting parts that can get clogged or damaged by viscous fluids, which makes them far less prone to failure compared to centrifugal or gear pumps when handling thick materials.
Antlia AODD pumps are used across industries to transfer a wide range of viscous and thick fluids:
The diaphragm material plays a critical role in the ability of an AODD pump to transfer viscous materials. The right diaphragm must be able to withstand the shear forces generated by the viscous fluid and maintain its shape and integrity over extended operation.
The three most recommended diaphragm materials for viscous fluid applications are:
Good resistance to oils, fuels, lubricants, and petroleum-based fluids. Most economical option for viscous oil-based applications.
Excellent resistance to solvents, inks, chemicals, and high-temperature viscous fluids. Suitable for demanding industrial applications.
Best chemical resistance across the widest range of fluids. Ideal for aggressive chemicals, adhesives, and viscous pharmaceutical fluids.
Overall, AODD pumps are a reliable and effective option for transferring viscous materials across a wide variety of industrial applications. Their key advantages for viscous fluid handling include:

They generate high suction and discharge pressure, and have no close-fitting parts that can clog — making them ideal for thick fluid transfer.
Buna-N, Viton, and PTFE are the recommended diaphragm materials for viscous fluid applications. These materials withstand the shear forces generated by viscous fluids and maintain their shape over time. PTFE offers the broadest chemical compatibility while Buna-N is most economical for oil-based fluids.
Antlia AODD pumps can transfer oils, lubricants, inks, adhesives, glue, paint, resins, creams, pastes, grease, slurries, and other thick industrial fluids across food, pharmaceutical, chemical, and manufacturing industries.
AODD pumps are preferred because they generate high suction and discharge pressure, have no close-fitting parts that clog, are self-priming, can run dry without damage, work without electricity, and offer a wide range of diaphragm materials for chemical compatibility.
