Japan ShinanoKenshi developed a silent type solenoid driven piston pump

Japan ShinanoKenshi company (Headquarters: Ueda City, Nagano Prefecture) has developed a universal electromagnetic drive piston pump "MicroPump Aqua", even if the liquid transmission line mixed with gas can also be self-priming. The product will be available by the end of June 2006 prototype. Typically, this reciprocating piston pump is prone to noise, and this new product utilizes a unique electronic control method and optimized valve design to achieve superior mute characteristics. In the relatively high flow applications, suitable for conveying water pipes and propylene glycol antifreeze and other liquids. Production is scheduled to begin in January 2007. The new pump introduces water into the pump even without water, so you do not have to worry about mixing with gas and can be used with confidence. Therefore, real machine attitude conditions and conditions of use less restricted. And because of small size, so the real machine embedded in the micro-pump design not only the configuration of high degree of freedom, but also to achieve space-saving design. Power transmission using magnetic force. Piston can be driven without sliding seal, ensuring high sealing performance over long periods of time. The main specifications are as follows: power supply voltage is DC7.5 ~ 13.2V, drive frequency is 15Hz. The maximum flow rate is 400mL / min (DC12V drive, water pipe at room temperature). The maximum pressure of 12kPa (ibid.), Life of more than 8000 hours (ibid.). Material complies with RoHS directive.
