Method for recovering noble gases using a diaphragm pump.

ケーエヌエフ・ジャパン ケーエヌエフ・ジャパン KNF JAPAN
Noble gases such as helium, neon, and argon are essential in a wide range of industries and scientific research. From aerospace applications to the semiconductor industry, their unique properties bring significant benefits. The recovery of noble gases not only helps protect natural resources but also reduces the environmental impact of their production. By recovering and reusing these gases, the industry can minimize waste and reduce dependence on new gas sources, contributing not only to economic benefits but also to overall sustainability. Two-stage diaphragm pumps like the KNF N630.15 series are particularly advantageous for the recovery of noble gases. They combine efficient and reliable performance under harsh conditions with flexibility to accommodate a wide range of capacities, pressures, and gas compositions. Additionally, their compact design and inherent gas-tightness minimize gas leakage while providing high versatility and customizability for applications ranging from small to large scale. To ensure this, these pumps undergo additional helium leak testing before shipment.
