Nikkei BP Press Release April 19, 2006 Japan Shinano Kenshi Corporation (Headquarters: Ueda City, Nagano Prefecture) recently developed and trial-produced a fingertip-sized, low-power diaphragm micropump that is small in size and light in weight and available Low-voltage drive. Prototype size of 14mm in diameter, length 14mm, weight 9g. Compared with the old piston miniature pump released in 2004, the size is about 1/4 and the weight is about 1/10. The world's smallest solenoid-driven diaphragm micro-pump. Using self-developed magnetic circuit, 0.4W low power consumption characteristics. Because it can be driven with a low voltage of 3V, it can be powered directly from the battery without using a boost circuit. But also make 5V specifications products. In addition, by optimizing the structure of the various parts, improve the efficiency of the pump. Maximum flow and maximum pressure were reached 30ml / min and 9kPa. Drive frequency is 10Hz. Can transport a variety of liquids, and methanol resistance is good. Also self-priming, even if the transfer of liquid mixed with air bubbles can be stable operation. In addition there are specifications for conveying air. In addition to DMFCs (Direct Methanol Fuel Cells), steam generators and various analytical instruments, its use will be broadened primarily in liquid transport. According to the purpose of use, change to the best specifications. At the same time, it is still exploring the future with a well-controlled drive circuit. The company plans to showcase two models at the Techno-Frontier 2006 Motor Technology Show held on April 19-21, 2006 in Messe, Chiba, Japan.
