Stefan Hörnschemeyer reports on pumps which are operating in some of the most contaminated water treatment sites in Europe and which are proving successful at processing aggressive leachates under extreme conditions. Dorothea Lange looks at the impact of the ATEX Directive 94/9/EC on pumps. In the stainless steel component sector for hydraulic applications, Parker now offers one of the largest product lines in the world. For years, a major manufacturer of natural and synthetic additives struggled to maintain its pH probes in the face of aggressive processes. In the end it opted for a new probe design that has solved the maintenance problems. Sean Ottewell reports. In the stainless steel component sector for hydraulic applications, Parker now offers one of the largest product lines in the world. The ac drive manufacturer Vacon’s System Interface Application is designed to provide machine controllers with a logical and flexible interface to be used in demanding applications. Willy A Bachofen AG Maschinenfabrik has developed a small agitator bead mill for its Dyno-Mill Research Lab. Moisture Control and Measurement Ltd (MCM) has recently fulfilled a contract to design and supply moisture measurement systems for a new helium recovery plant at BOC Gases plant in the UK. The new LPP80 peristaltic pump from Larox Flowsys is designed to meet the demands of a high-volume process in heavy industry duties, particularly in mineral processing and metallurgical applications. Users from the power generation, petrochemical and industrial chemicals industries are frequently confronted with extreme pressure differentials in their plants – differentials up to 400bar are not rare in this regard.  It is a suitable system for start-up and boiler-feed water recirculation. The involvement of the world’s leading sensor manufacturers in a new non-proprietary inductive connector system will allow users to retain their tried and tested pH electrodes, without depending on sensors from a single manufacturer. In an advance that could lead to composite materials with virtually limitless performance capabilities, a University of Wisconsin-Madison scientist has dispelled a 50-year-old theoretical notion that composite materials must be made only of ‘stable’ individual materials to be stable overall. Two new fluid seals, from James Walker, will cut maintenance and improve the reliability and profitability of water turbines in hydropower plant. Depu is an ATEX-approved, universal on-site solution for controlling/limiting temperature and for controlling power. The new Vacon NXL is a powerful and compact ac drive for industrial and building automation available up to 30kW in 400V. prev    next
