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.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
