A medium-sized model with a wide range of applications for both discharge pressure and flow rate. It has a proven track record in circulation applications such as semiconductor process gases and helium-3.
The metal bellows pump is a positive displacement pump that utilizes the characteristics of a flexible stainless steel bellows diaphragm. It can be used as a vacuum pump for gases and as a booster compressor. 【Features】 ■ Excellent airtightness Leak tightness: 1.0x10E-7 to 1.0x10E-9 std.cc/sec (He) ■ No contamination The design has no wear parts, preventing contamination of the fluid gas ■ High corrosion resistance The gas-contacting parts are made of 300 series stainless steel, and the valve gaskets use Teflon or Viton. By selecting aluminum O-ring gaskets as an option, the gas-contacting parts can be made entirely of metal. ■ Long lifespan The bellows and valves in the moving parts are designed and manufactured to operate below the durability limits of the materials used, allowing them to withstand nearly infinite motion cycles. *For detailed specifications and technical materials, please refer to the "Comprehensive Catalog."
