KNF’s Type NMP05 diaphragm micropump for sampling air and gases features miniature packaging and is designed for a range of portable, battery-operated equipment applications. The miniature OEM pump measures 17mm (width) by 26mm (height) by 31mm (length) and weighs as little as 18 g. The micropumps are a good fit for industrial hygiene devices, air samplers, and medical analyzers, among other uses. Features include a bolted-on pump head, ensuring gas tightness, and an innovative molded diaphragm with structured surface, enabling maximum end vacuum and extended lifetime. A variety of economical, low-current, brush-type DC motors or premium, longer-life, ironless-core DC and BLDC motors with integrated electronics featuring low EMI/RFI can be specified. A valve system promotes low aerodynamic loss and optimized flow. Oil-less operation allows for uncontaminated flow of the pumped medium. Depending on model, this pump can achieve flowrates to 450 ml/min., continuous vacuum to 500 mbar (15.2 in. Hg), and continuous pressure to 150 mbar (2.2 PSIG). – knf.com/oemicro
