SOLARBUILDERMAG.COM | 23 age from ARO, a brand of Ingersoll Rand. Sealant dispensing systems all have a piston pump package that includes the transfer seal- ant, a metering unit to ensure dispensing accuracy, a dispensing valve for on/off control and a work table to hold the frame and con- trol the movement of the dispensing valve. After the dispensing process is complete, the frames are transferred by machine or by man- power to the panel assembly machine. When developed correctly, a solar panel should last for about 25 to 30 years from installation to retirement. For Shanghai Shengpu, an ARO piston pump package was a better fit for ensuring proper panel development compared to the previously used pump system for three key reasons: 1. ARO piston pumps offer the right pressure for sealant dispensing 2. ARO piston pumps offer service packages for pump repair or maintenance 3. The ARO team proposed many pump suggestions that were applied to improve the dispensing process "The implementation of the ARO piston pump package into our dispensing systems brought immediate benefits to our process," said Fu Jianyi, general manager at Shanghai Shengpu. "The biggest improvement was the ARO team's recommendation to implement a new follower plate. Previously, sealant was left behind in the drum resulting in a significant amount of waste. With the help of ARO, we improved the structure of the plate resulting in 50 percent less waste." With a wide selection of pressure ratios and displacement rates available, ARO offers a variety of application packages preconfigured with the right motor, piston pump, mount, controls and downstream accessories. Packages range and offer multiple configura- tions, including single-post, two-post and heavy-duty two-post, to ensure the best solu- tion for the application. Preassembled and validated application packages eliminate the guesswork that comes with choosing the opti- mal pump. For Shanghai Shengpu, the ARO 55-gallon, two-post ram piston pump pack- age was best suited for creating the dispensing system. A Growing Market When Shanghai Shengpu implemented the ARO piston pump package into its dispensing system development process, it was able to see significant improvements. In a market that is set to grow significantly over the next several years, ensuring that solar panels are developed the best way possible is only going to help the mar- ket get there faster.
