Hermetic-Pumpen The newly developed HCN/HCNF range of canned motor pumps was designed for the most demanding areas of application. The HCN range is designed for aggressive, inflammable, toxic and highly volatile liquids, solvents or other substances. The HCNF range is…
A new, explosive decompression-resistant perfluoroelastomer has been launched for use in ultra-agressive processing applications. The Perlast G92E elastomer combines high levels of chemical resistance with an increased explosive decompression capability, setting a new performance standard for seals in pumps, valves…
Samson Controls The air output capacity required to achieve fast positioning in large actuators (diaphragm areas of 1,400–2,800 cm2) is too much for normal positioners, and so positioning accuracy can be compromised. A solution to this problem is a control-valve…
AtlasCopco Compessors A prominent design feature of ZS Series blowers (photo) is their application of rotary screw compression technology. The rotary screw concept helps the blower to operate at efficiencies 35–40% higher than traditional tri-lobe blowers at a compression ratio…
Dickow Pump The Series NMWR seal-less centrifugal pumps (photo) have magnetic couplings and no shaft duct to the atmosphere, and are available with maximum capacity to 4,000 gal/min and differential head to 500 ft. The containmment shell forms a closed…
Eight different pump sizes encompass the new Dolphin LS Series of liquid-ring vacuum pumps. The single-stage liquid-ring vacuum pumps in block construction achieve ultimate pressures of 33 mbar, and have suction capacities over the range of 25 to 455 m3/h.…
A new line of Krombach Metal Seated Ball Valves features machining of the ball and seat to such high tolerences that ball-and-seat lapping does not have to be performed individually for each valve. The tight tolerances make the ball and…
Tideflex Technologies The CheckMate inline check valve (photo) is ideal for backflow prevention and odor mitigation. The valve’s unique elastomer fabric-reinforced design provides a proven record of maintenance-free performance and cost savings. The CheckMate has an extremely low headloss, so…
Edwards This firm has expanded its iXY family of magnetically levitated turbomolecular pumps with the introduction of the STP-iXA2206 and STP-iXA3306 pumps (photo). Developed for solar, glass-coating, semiconductor and LCD-etch applications, the new pumps are fully integrated vacuum pumps that…
Available in galvanized steel, stainless steel and brass, Nilos rings (photo, p. 64) safeguard ball and roller bearings from the corrosive effects of abrasive particles and debris. The rings can be specified in a wide range of sizes to seal…
