Examples of the use of KNF pumps in biogas treatment systems.

Process pumps for research and development related to decarbonization and new energy, for the transfer, recovery, and circulation of CO2, hydrogen, oxygen, helium, and others.

In a decarbonized society and the development of new energy, there are many technical challenges that conventional gas pumps cannot adequately address. We believe that the KNF process pump, with its features listed below, can assist in solving our customers' technical challenges. Main features of the KNF process pump: - Contamination-free - A wide range of gas contact materials - Pressure-specific design with a maximum allowable discharge pressure of 1.2 MPa - Vacuum-specific design - Leak-tight design - Long lifespan design - Explosion-proof specifications (optional IECEx / ATEX) - Heat-resistant specifications with gas temperatures up to 240°C (optional) - Weather-resistant coating (optional)

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.
