Traditionally, most students have learned about chemical reactions in laboratories using test tubes, beakers and flasks. Those who have gone on to discover and develop new products have typically done so using these batchwise techniques. This mind-set has continued through…
Specially developed for the specific applications of mechanical seals, the Diamond Faces crystalline diamond layers promise excellent chemical and thermal stability as well as unmatched hardness. The material is stable up to approximately 1,500°C in inert atmospheres, where it begins…
This firm’s Series 3730 and 3731 positioners now include all diagnostic features as standard; previously, these features were only available at a extra cost. The onboard Expert+ firmware automatically records relevant data to monitor the valve and positioner. Required key…
Available in full or standard port, the new 364 Series Diverter valve offers such features as "live-loaded" stem packing, ISO 5211 direct-mount actuation and a variety of seat options. Made to full ANSI class 600 dimensions, this Inline valve handles…
The new Jamesbury polymeric-seated flanged ball valves are now available in sizes DN15 – 150 in both full-bore and reduced bore. These valves conform to PED and ISO 17292 requirements, and feature a flexible-lip seat design that provides bi-directional shutoff…
Made from high-performance polypropylene, these liquid-transfer pumps (photo, p. 32I-7) will safely deliver most solvents, acids, caustics and oils from 5–55-gal drums at a rate of 4 gal/min, depending on the viscosity. Typically, owners will need to change O-rings once…
For applications requiring control valves that are capable of withstanding the effects of highly corrosive media, the Badger RC250 barstock valves (photo) are said to be the ideal choice. The valves are available in a range of materials, including stainless…
The Goulds VRS vertical rubber-lined cantilever sump pump is said to set new standards for energy efficiency and other costs. The VRS liners, impellers and casing halves are all interchangeable with the firm’s SRL horizontal pumps, resulting in reduced parts…
The Hydrotwin (photo) is a compact vacuum-pump package that guarantees a vacuum level down to 5 mbar (absolute) — previously not achievable by conventional stand-alone liquid-ring vacuum pumps, says the manufacturer. Capacities of up to 2,000 m3/h can be handled…
This company has recently unveiled the GX 3-Way control valve (photo), which has the ability to accurately control the temperature of water, oils, steam, and other industrial fluids. Applications include heat exchangers and lubricating skids. The flow cavity of the…
