Reduces air consumption
Field testing shows up to 50% savings over conventional AODD pumps. AirVantage Technology is available with Sandpiper® metallic pumps with discharge line sizes 2" or greater. Sandpiper center section upgrade kits are also available.
Adapts to process conditions
Using and advanced learning program that receives velocity feedback from an embedded sensor, AirVantage optimizes energy consumption and automatically adapts to changes in system demand, constantly managing energy consumption.
Powered only by compressed air
AirVantage uses a self-contained 12V power generator that converts a tiny portion of compressed air to power system electronics for managing energy.
Saves energy while maintining flow
Field trials have proven that AirVantage can maintain comparable flow capacity while reducing air consumption saving thousands of dollars in annual energy costs.
By using less air to operate pumps, AirVantage allows for more compressed air capacity system-wide to run more pumps generating greating productivity and better throughput.
Reduces compressor maintenance
Air compressors with reduced demand need fewer repairs, saving customers thousands of dollars in maintenance and repair costs.
Coming to market in August 2010, AirVantage Energy Saving Technology is used on air operated double diaphragm pumps (AODD), which are industrial pumps that employ the use of a twin diaphragm system for positive displacement to move liquids. Important specifications for diaphragm pumps include maximum discharge flow, maximum pressure discharge, inlet size, discharge size and media temperature. Power sources are primarily pneumatic or hydraulic and incorporate the use of compressed air or natural gas.
AODD pumps with AirVantage® Energy Saving Technology are equipped with a microprocessor that is adaptive and continuously manages the amount of air volume required to operate the pump at the desired flow rates. This technology determines the optimal diaphragm rod velocity and relays the information to an air distribution valve at the air inlet location of the pump. The valve acts as a gated air management system, allowing only enough air to enter each inner pump chamber. Diaphragms perform at their optimal operating point, with less air consumption. As the pump experiences air inlet fluctuations or other changes that affect air flow, the system adapts to optimize the pump’s performance.
AirVantage uses existing air flow to provide its own electricity and power to the device. This eliminates the need for batteries or hard wiring. No training or special set up is required to operate the energy saving technology, which installs in the same way as traditional AODD pumps.
This product was tested at 20 manufacturing facilities during an 18-month period. During these tests, Warren Rupp validated that AirVantage saves up to 50 percent air consumption over competitive pumps when applied to heavy flow applications. This information was validated by SCFM meters and recorded on data-loggers within these facilities.
Warren Rupp has published comparison charts showing greater than 50 percent energy consumption versus major pump brands on a 3-inch pump comparison point 150 gallons per minute and 40-psi head. This information is based on published performance curves. At 150 gallons per minute/40-psi head , Versa-Matic AirVantage air consumption is 67 standard cubic feet per minute (SCFM), where other manufacturers’ AAOD pumps measured 155 SCFM, 150 SCFM and 117 SCFM (manufacturers’ names were removed by the editors of Pumps & Systems for the purposes of this article). These comparisons are indisputable when comparing published data sheets.
AirVantage has also qualified under the Iowa Custom Energy Rebate Program as an energy saving technology where the utility (MidAmerican Energy) has committed project funding to install the equipment.

The Saint-Gobain Grains and Powders Manufacturing facility took on a 30-day energy savings challenge. The facility reduced its energy costs by 23 percent at its fluid separation points, the most process-critical applications within the facility, according to Rick Klok. They perform several functions and run 24 hours per day, seven days per week.
"Over this period of time, AirVantage reduced our air consumption by 23 percent while maintaining our desired flow rates," Klok says. "It was simple. All we did was install the trial AirVantage pump, and it did the rest, optimizing our energy consumption without special
handling or monitoring. As the pump application switched from batch transfer to recirculation to fluid separation, the AirVantage self-adjusted to the pressure drops and changing condition-points all by itself, using just the right amount of compressed air to operate our pump.
At the end of the product trial, the test results showed the amount of compressed air that the pump consumed with AirVantage versus data points collected before the product trial began.
"We were surprised to learn that we can save as much as $1,200 in energy costs and increase our air compressor capacity by 2.5 horsepower per pump," Klok says. "We were very satisfied with the performance of the new system, and we plan to use AirVantage on all [our] AODD pumps in the future."
