Rugged AODD Solutions for Demanding Applications

Chemical processing applications often require pumps that can handle aggressive fluids,
changing operating conditions, and a wide range of material compatibility needs. From
acids and alkalis to solvents, hydrocarbons, powders, and process chemicals, selecting
the right pump construction is critical to reliable fluid transfer.

Yamada air-operated double diaphragm pumps are built for demanding chemical applications,
with a broad selection of wetted materials, elastomer options, and specialty pump
configurations available to match the needs of the process.

Material Options for Demanding Chemical Service

One of the most important considerations in chemical pumping is material compatibility.
Yamada chemical pumps are available with wetted materials including
316 Stainless Steel, Aluminum, Cast Iron, Polypropylene, Acetal, PVDF, and PTFE.
Yamada also offers seven internal elastomer options, giving users flexibility when
selecting a pump for specific chemical requirements.

This range of material options helps support applications involving corrosive fluids,
hydrocarbons, powders, and other difficult-to-handle materials. For best results,
pump selection should always be reviewed against the specific chemical, concentration,
temperature, and operating conditions of the application.

Operating Capabilities

Yamada lists operable fluid temperatures from -40°F to 350°F,
with pressures up to 200 PSI. Yamada pumps are also described as
self-priming, portable, intrinsically safe, and capable of running dry.

These characteristics make Yamada AODD pumps a practical option for chemical plants
and industrial facilities where fluid transfer requirements can vary from one process
area to another.

Specialty Pump Options

Yamada offers specialty pump options for applications that require more than a standard
configuration. Available specialty pump categories include:

• Drum pumps
• FDA-compliant pumps
• UL Listed pumps
• CSA Listed pumps
• Electro-polished pumps
• 2:1 high-pressure pumps
• Powder pumps
• Batching pumps

When a listing, compliance requirement, or specialty construction is needed, the exact
pump model and documentation should be confirmed before final selection.

Common Chemical Processing Applications

Yamada pumps are used in chemical plants to transfer and circulate a variety of
chemicals, including acids, alkalis, solvents, and more. Common chemical processing
applications include:

• Mixing
• Filter press
• Utility transfer
• Packaging
• Batching
• Tanker and rail-car unloading
• Bulk transfer
• Day tank transfer
• Injection
• Drum transfer
• Processing

Industries Served

Yamada chemical pump applications support a wide range of industries, including
rubber and plastic, textiles, petroleum refining, semiconductor, pulp and paper,
primary metals, pharmaceutical, glass, paint, ink, adhesives and sealants,
food and beverage, and plating.

Choosing the Right Yamada Pump

The right pump depends on the fluid being handled, required flow rate, pressure,
temperature, material compatibility, suction conditions, and installation environment.
Yamada provides a chemical compatibility resource for reviewing pump options against
specific chemicals, and Fischer Process Industries can help evaluate the application
details before selection.
