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?

“Time is money” is a common refrain in business. When it comes to air-operated double-diaphragm pumps (AODD) pumps in fluid handling operations, “downtime is money” is an even more accurate phrase. Your company achieves its goals and serves customers best when your AODD pumps are functioning properly, not when they’re out of service.
