In industrial environments, pump performance is not only about flow rate. It comes down to how efficiently a pump runs, how quickly it can be serviced, and how reliably it keeps operating day after day.

If you have ever ordered, specified, repaired, or supported an industrial pump, you have probably faced a familiar moment: you are looking at a model number and trying to confirm exactly what it represents. Is it the same pump you used last year? Is it the right material set for the fluid? Does it meet your site requirements? Does it include the safety rating you need?

Behind every good Rockstar is a crew that builds the stage, prepares the pyrotechnics, sets up the lights, and does all the sound checks. It’s no different when the Rockstar is an AODD (air-operated double-diaphragm) pump. In fact, our team is so good that every pump in the Versamatic lineup benefits from the work they do.

Valor, noun [latin valor valeo, to be strong, to be worth]; courage, bravery, prowess. So why give that name to a silly old AODD pump, you might ask? The answer is two-fold.

Most people think of long black hair, electric guitars, leather, and illicit substances when they hear the word “Rockstar”. In the pumping world, we’re talking about a much different image, however. Rather than a rap sheet tied with a wild lifestyle that risks a premature end, our Rockstar air-operated double-diaphragm pump boasts just the opposite.

If your job involves pumping slurries and solid-laden fluids, you know it’s not always an easy task. Slurries and solid-laden fluids provide unique challenges:

Pumping problems are frustrating in any fluid handling application because they typically result in lost production time and wasted resources. Air-operated double-diaphragm (AODD) pumps are known for being easy to operate and user-friendly — simply plug in your air and connect your suction and discharge lines and you’re ready to go. But you can still run into pumping challenges from time to time.

When selecting an air-operated double-diaphragm (AODD) pump for your application, you might ask yourself, “Would a standard AODD pump work well for my application, or do I need a specialty unit?” Unique aspects of your application may require specialty diaphragm pumps, such as FDA-compliant pumps, 3-A certified pumps, high-pressure or centrifugal pumps.

When it comes to selecting air-operated double-diaphragm (AODD) pump materials, there are some rules of thumb.
