Edwards

EdwardsEdwards recently introduced a new GXS dry pump designed to support pumping requirements for silicon ingot manufacturing and laminator applications in the solar industry. The GXS provides the optimized thermal control and dust handling capability needed to meet the pumping challenges encountered in these processes. The high atmospheric pumping speed capability of the GXS also enables faster chamber pump down, reducing cycle times and improving throughput. GXS uses a tapered variable pitch screw profile (patent pending) that allows for tight clearances without the need for rotor coatings. It also enables compression variations along the rotor axis for improved thermal stability and better thermal control, making it an optimal pump to handle the high flows of argon gas used in crystal pulling applications, as well as the dust generated during the manufacturing process. The GXS dry pump can operate on as little as 3.9 kW of input power (depending on the pump version) and uses 57% less energy than competing piston pumps.
