The new KNF NF600 self-priming diaphragm pump for dosing or transferring liquids incorporates advanced four-diaphragm technology to promote smoother and continuous flow, low pulsation and vibration, quiet-running performance, and maximized efficiency. This compact solution (as small as 135 mm x 111 mm x 105 mm) can deliver a nominal flow rate of 6 l/min, suction height of 8.8 in. Hg, and pressure up to 15 psig. These pumps are well equipped for medical diagnostic analyzers, dialysis liquid circulation, water treatment and analysis, ink-jet printers, and semiconductor operations, among other applications.NF600 pumps are available in three motor types (ac, brush-commutated dc, or brushless dc) and can provide stable pumping action over a potential service life exceeding 50,000 hours. The pumps require minimal maintenance and are designed without tubing to eliminate possible pump failure due to tubing fatigue or rupture. Their corrosion-resistant PP/PVDF/FFPM/PTFE envelope can handle acids, caustics, and other harsh materials. Highly chemical-resistant versions expand application potential.
Other noteworthy pump features include NFS grade TPF and TP heads and specially engineered anchor valves contributing precision and reliability. A wide standard range of materials, voltages, and frequencies can be specified and pumps can be easily customized for any application. Specialized accessories include diaphragm pressure control valves, pulsation dampers and hoses.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
