4 times the maximum flow of the old models! Star developed a new small fuel cell pump

Star Precision has now developed a maximum flow rate of 20mL / min small pump "SDMP320." This is a diaphragm pump using a piezoelectric element that consumes less power because it does not use a motor and shaft. Mainly for small fuel cell fuel supply and a variety of analytical equipment such as liquid delivery purposes. The company hopes to put the pump into production in the future. SDMP320 maximum flow is the company in November 2005 released "SDMP305" 4 times. This is expected to be used as a fuel pump for delivering diluted methanol fuel to small fuel cells. However, the external dimensions of the pump are 33 × 33 × 5.5mm, larger than 305 (25 × 25 × 4.8mm). According to the volume comparison, 320 is about 305 times 2 times. The diaphragm material uses COC (Cyclic Olefin Copolym) resin, the valve material uses EPDM rubber material the same as 305. Other specifications in the table below.
