Before I started working for EXAIR, I spent several years in industrial fluid handling dealing with pumps, valves, mixers, mechanical seals, etc. In this time I held several different titles and was able to gain a lot of experience with not only the specific product but the various processes where they might be used. Making the change from fluid handling products to compressed air operated products, I was a little apprehensive as to how or where my previous experiences might possibly play a role in my new career path but surprisingly it has actually been more beneficial than I originally thought.
Such was the case during a recent conversation with a customer regarding their drum emptying application. They were currently using an AODD (Air Operated Double Diaphragm) pump to empty drums of coolant. A diaphragm pump uses compressed air as it’s power source and is one of the more common pumping solutions due to the relatively low purchase price and seal-less design. The problem with these types of pumps is the diaphragms and shafts fail over time due to the repeated stress from the shaft movement. When failure occurs, the liquid is able to get behind the diaphragm which can bleed back into the air motor, resulting in complete failure and costly rebuild due to parts and labor or replacement. This customer had a failed pump and was facing the rebuild cost and process.
To replace the existing diaphragm pump, I recommended the customer use our Model # 6196 Reversible Drum Vac. The Reversible Drum Vac is a compressed air operated pump / vacuum system that attaches to a closed head steel drum and is capable of emptying or filling a 55 gallon drum in 90 seconds. In “empty” mode, the unit pressurizes the drum which forces the liquid inside to be pumped back out of the flexible hose at a rate of 30 GPM. By pressurizing the drum, the Reversible Drum Vac itself never sees the liquid, leading to prolonged performance. In addition, there are no motors or diaphragms to wear out, providing virtually maintenance-free operation.
By switching to the Reversible Drum Vac, the customer was able to keep the process compressed air driven and eliminate the concern over failed components and expensive labor hours. If you are experiencing a similar situation, please give us a call so we can provide assistance.
