In part one of this multi-part blog series, we discussed the basics of air operated double diaphragm pumps and their numerous uses throughout a wide range of industries. These plastic products are known to do well with viscous or abrasive materials and their movement needs, a big part of why they’re so wildly popular across various areas.

At EnviroTech Custom Injection Molders, pump components are just one of several custom plastic injection molding areas we provide our clients with, including those for AODD pumps you might require. Here are several more applications and industries where these pumps are highly useful and often utilized.

Pharmaceutical Industry

Within the testing areas of the pharmaceutical industry, numerous fluids with high viscosity or which contain particles will need to be pumped to and from facilities. This is a perfect use of AODD pumps, which can handle a large variety of such chemicals, whether we’re talking proteins and enzymes or vitamins, vegetable extracts, blood plasma, waste solvents and many others.

For this reason, you’ll find AODD pumps throughout such facilities. Their most common applications are filtering, aseptic transfer, tablet coating, reactor production and wastewater treatment.

Cosmetics and Soaps

From the raw materials all the way to the end product, many of the solutions found in the cosmetic industry are highly viscous. This industry deals with things like lotions, fabric softeners, soaps, creams, shampoos, foaming agents and various gels, all of which can be easily carried and transported by AODD pumps from one location to another while production is taking place.

Steel World

If you weren’t previously aware, steel manufacturing is a process that requires the use of several potential liquids and related applications. Areas like core flushing, mold release, galvanization and even rolling mills all find uses for AODD pumps, which can transfer everything from metal sludge and dust scrub slurry to drainage water, grinding oil and corrosion inhibition products.


The most common application of AODD pumps within the electrical industry is ultrasonic washing and electroplating bathing, areas that require multiple liquids handled. These pumps can handle ultrapure liquids, solvents, various acid formats, electrolytes and anodic sludge, all of which are needed to create conductivity and electronics.

Galvanic Chemicals

We went over general chemical plants in part one of this series, but it’s also important to note the specific area of galvanic chemicals. These are known to be aggressive fluids, such as waste products filled with metallic solid particles. AODD pumps are great within this field for surface treatment, galvanic baths, electrostatic plating, plus polishing and filtering systems.
