Liquiflo Polygard Series pumps (photo) are perfluoroalkoxy-lined (PFA) magnet-drive gear pumps for moving challenging liquids, such as acids (including hydrochloric, sulfuric, hydrofluoric, nitric and chromic), ferric chloride and sodium hydroxide. These pumps feature non-metallic wetted parts and zero leakage. They…
This company has introduced the new S Series of screw pumps (photo) for conveying challenging fluids. These rotary positive-displacement pumps are ATEX-certified for use in explosive or dangerous environments. They are self-priming, and deliver a constant flow with low pulsations,…
SL submersible wastewater pumps (photo) are designed to handle raw sewage, effluent and large volumes of surface and process water in municipal, utility and industrial applications. The solids-handing pump series, with motor ranges from 1.5 to 15 hp, is available…
The BR series of backpressure regulators (photo) features a blockage-resistant design geared toward supercritical CO2 extraction, as well as other processes in which clogging, blocking or freezing are potential problems. The BR series relies on internal passages to eliminate convergence…
The Vorecon with Dual Torque Converter (photo) is a variable-speed planetary gear with two matched torque converters. It delivers high efficiency, even into the lower speed range, providing an efficient way to control the speed of large pumps and compressors…
Clampseal blowdown service valves provide necessary control for continuous or tandem boiler or turbine blowdown and bottom blow-off service. The blowdown valves are available in sizes ranging from 3/4 to 4 in., with butt- or socket-weld and flanged ends in…
This company rounds off its proven series of Ecotrol control valves at the high end with the development of the nominal size DN 700 (28 in.). This valve has been specially optimized for use as an anti-surge valve on turbocompressors,…
This company has developed a new repeater-node technology that, according to company, will provide both redundancy and additional reach not currently available in a standard point-to-multipoint systems. The repeater-node system will help extend range by connecting several repeaters, enabling switching…
Conventional dust-measuring devices are unable to differentiate between dust particles and water droplets, resulting in incorrect measurement results. The FWE200DH provides the solution: the dust-measuring device continually extracts the waste gas from the stack, dries it with a thermocyclone, and…
This company’s Sine Wave Filter products eliminate premature motor damage from overvoltages, cable ringing, motor overheating and eddy-current losses caused by variable frequency drives (VFDs). Suitable for motor frequencies up to 600 Hz, this technology converts the rectangular pulse-width modulation…
