Explosion-proof certification in Japan - Explosion-proof gas pump

ケーエヌエフ・ジャパン KNF JAPAN

The explosion-proof gas pumps of the N87 series and N922 series, which have received positive feedback for sampling combustible gases and gas transfer, have passed the explosion-proof structure electrical equipment type certification in Japan. Against the backdrop of initiatives such as the "2050 Carbon Neutral Declaration," applications handling combustible gases, including methanation and hydrogen gas utilization, are increasing daily, and practical demonstration experiments are actively being conducted. KNF offers a wide range of explosion-proof gas pumps certified with IECEX / ATEX that are suitable for combustible gases, including hydrogen gas, and many customers are already using them. In response to the demand for explosion-proof certified products in Japan, we have obtained explosion-proof certification for two models of compact gas pumps.
