Bio-Chem Valve and Omnifit’s Model 30 4-L micro pump accurately and efficiently dispenses low-pressure micro-flows of high-purity or aggressive liquids. Designed for speed in cycling, the miniature, lighter pump utilizes a fast response solenoid that is capable of quickly dispensing micro volumes. It offers up to 20 million dispense cycles and features low power consumption, minimal heat generation, low internal volume and a positive shut-off. The diaphragm is made of PTFE; the pump body is formed of PPS as a standard and the check valve is DuPont Viton® or FKM. The simple addition of a screw nut offers a quick-change manifold mount connection.www.bio-chemvalve.commsalviano@bio-chemvalve.com
