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.

The KNF high-output liquid pump enables stable liquid delivery against high back pressure. It is available in a lineup categorized by flow rate types. Standard specification high-output liquid pump: Maximum allowable discharge pressure 0.6 MPa Special specification high-output liquid pump: Maximum allowable discharge pressure 1.6 MPa (NF2.35 series) - Abundant wetted materials Available from inexpensive EPDM to highly corrosion-resistant Perfluoro materials. Capable of high-pressure transfer of solvent-based and cleaning liquids. - Compression fittings The pump joints come standard with highly compatible connectors. - Brushless DC motor Flow control is possible through analog control or PWM control. - No restrictions on installation direction There are no restrictions on the installation of the pump.

This explains a simple way to read the flow curves (performance curves) found in pump data sheets, etc. The video explains the flow curve for gas pumps, but the basic reading method is the same for liquid pumps, swing piston compressors, and others. If you have any questions regarding the flow curves of individual pumps, please feel free to contact our experts.

In medical applications where system reliability is essential, the high-quality and reliable KNF diaphragm pumps have a long history of adoption in medical systems and analytical systems produced worldwide. *Examples of Adoption - Biochemical automatic analyzers Blood testing devices (blood analysis, blood cell counters, etc.) Urinalysis devices, fecal occult blood analysis devices, etc. - Immunoassay devices, bioanalytical devices, molecular biology - Endoscope cleaning devices - Artificial dialysis - Various sterilization, disinfection, cooling, etc. *Main Product Features - Design specialized for drainage and waste liquids - Longevity - Corrosion resistance - Maintainability - Compact, lightweight, and quiet - Installability

As efforts towards carbon neutrality by 2050 and the realization of a hydrogen society gain attention, KNF is seeing an increase in inquiries regarding various process gases. * Gases with increasing inquiries: - Carbon dioxide - Hydrogen - Methane - Oxygen, etc. At KNF, we have prepared a simple presentation material regarding pumps for process gases. It explains the features of our process pumps and various data sheets, so we would appreciate it if you could refer to it.

In February 2021, we translated into Japanese the presentation materials used in the webinar "Market Trends in Inkjet and KNF's Initiatives" that KNF presented at DRUPA (International Printing and Media Industry Exhibition), which was held as a virtual exhibition. The main themes are as follows: - Pulsation-reducing liquid pump - Digitally customizable DC motor - Vacuum pump for degassing - Meniscus countermeasures for printer heads, etc.

KNF's OEM pumps (equipment integration type) can be customized to meet various challenges of our customers. Here, we would like to introduce the KNF modular system.
