ASCO Numatics introduces low power Ex d pilot valve with IEC Ex Approval (25/02/2010)
ASCO Numatics announces the new (WS)LPKF low power pilot with Ex d certification for the compact 551, 552 and 553 series pilot valves. The valve is available with either an aluminium or stainless steel enclosure, and with a power consumption of just 0.5W at 24V DC, has the lowest consumption of any Ex d certified valve for the process industry. The low wattage coil reduces battery drain and heat rise, minimises wiring costs and provides energy savings. The savings in power...
Total vehicle management system can achieve up to 50% fuel savings, says Haldex (22/02/2010)
Haldex Hydraulics has introduced a total vehicle management system, which provides more efficient and economic operation of all powered functions in a wide variety of mobile equipment from wheel loaders and excavators to lift trucks. Other hydraulic hybrid systems capture braking energy, store it and redeploy the stored energy for propulsion. The Haldex EMS system is the only hydraulic hybrid that provides energy management for the...
PM hails UK as 'global leader' in offshore wind market (18/02/2010)
The latest £8m funding for offshore wind technology was made available on Thursday (February 18) as the Prime Minister hailed the UK as a 'global leader' in the offshore wind market. The announcement came as Clipper Windpower confirmed that it is to start construction of a factory in Newcastle to build the biggest wind turbine blades in the world. Visiting the site where Clipper today confirmed it will employ up to 500...
Blow-off station eliminates static electricity and dust (17/02/2010)
The new Exair static eliminating blow-off station, which is available in the UK exclusively from Good Hand UK, delivers a concentrated flow of ionised air to remove dust and other contaminants from a charged surface. It is suitable for both bench top and machine mounting. The station uses Exair’s 'Stay Set' Ion Air jet to minimise compressed air use by inducing surrounding airflow at a ratio of 5:1. This focussed airstream...
Magnetically driven, seal-less pump range is extended (17/02/2010)
The range of 3M magnetically driven, seal-less pumps has been extended with new models, including the CT MAG-MS, a peripheral multi-stage metallic mag-drive pump. Available from liquids handling specialists pump Engineering, the MS series includes six options providing flows up to 24mc/h at heads up to 1,000m. These pumps are suitable for applications involving aggressive, hard-to-handle fluids and...
PTFE U-packings are now also available in 2mm rod diameter size (08/02/2010)
Simrit’s Forseal PTFE U-packings offer a range of piston rod seals and rod seals that can be pressurised on one side. Made from PTFE and featuring metallic pre-tension springs, these rings seal both statically and dynamically at temperatures ranging from -200 °C to +260 °C. In the event of thermal expansion, optimum contact pressure is ensured even in cases where this pressure cannot be generated by system pressure during operation.
Universal ion source technology depends on seal integrity (08/02/2010)
DP Seals helps Waters Corporation to create an award-winning family of liquid chromatography-mass spectrometry instruments. Accuracy and on-time delivery of the seal sets were critical to the launch dates for this new instrument technology Liquid chromatography-mass spectrometry (LC/MS) is an analytical chemistry technique combining the physical separation capabilities of liquid chromatography with the mass analysis capabilities of mass spectrometry. Mass spectrometry uses...
Leak-tight sealing for wafer handling module (08/02/2010)
Trelleborg has helped semiconductor process equipment supplier, AP&S to develop a leak-tight sealing system for a novel thin wafer carrying system. The new ‘Cyclop Sealing’ capsule can be added, with only minor modification, to any semiconductor fabrication line AP&S is a company that develops wet process equipment for the semiconductor industry. One of its more recent developments is the Cyclop Sealing capsule, a one-size-fits-all media tight carrying system that...
Fine-tuning seal performance is getting easier (08/02/2010)
The design engineer is now able to fine-tune the performance of equipment seals, thanks to the development of new materials and improved design and manufacturing techniques, as Darryl Turland explains Optimising sealing performance involves striking a balance between often competing properties: mechanical performance versus temperature resistance, versus chemical resistance, versus rapid gas decompression resistance and so on. The need for compromise is reducing all the...
PD pump range is expanded with new motor options (29/01/2010)
The established range of HNP positive displacement, internal gear pumps has been expanded to include new, larger pumps and more drive options to suit a wider range of applications. Available from pump specialists Michael Smith Engineers, the HNP 11500 Series provides flows between 0.2 to 1,150 ml/min and differential pressures between 0-60bar or 0-150bar, depending on the viscosity of the process fluid.
