Determining the proper preliminary size for centrifugal pumps during the initial stages of any pump-specification exercise requires numerous calculations and assumptions. This article reviews the steps needed to size centrifugal pumps during the early stages of a project, to support…
The new Hard Seat VHS Micro-Dispense Valve offers repeatable, non-contact dispensing of fluids in the nano- to microliter range. It features a precision zirconia ball and seat instead of a traditional elastomeric seal, thereby ensuring resistance to aggressive fluids, such…
An Australian team has developed a new molecular sieve that allows carbon dioxide molecules to be trapped and stored. Contrary to the way molecular sieves usually work, allowing smaller molecules through, the new sieve acts like a trapdoor, and allows…
Designed for flow chemistry applications, the patented Asia Syringe Pump is said to give users a tool for performing flow reactions not possible using HPLC pumps or “single-shot” syringe pumps. Used in combination with the Asia Pressurized Input Store, the…
Tygon S3 (safe, smart and sustainable) is said to be the first bio-based and phthalate-free tubing, and is the next generation of flexible tubing from this company for food and beverage manufacturers. Tygon S3 complies with FDA, NSF and 3-A…
Basoplast 450 P is a new and highly cost-efficient polymeric surface-sizing agent (PSA) for the packaging sector. The product is suited for linerboard grades and complements the manufacturer’s range of anionic PSA in the graphical paper market. By replacing cationic…
The surface engineering company MesoCoat, Inc. (Euclid, Ohio; www.mesocoat.com) recently started up a facility for manufacturing clad pipe for the oil-and-gas industry that uses the company’s proprietary fusion-cladding technology to apply corrosion-resistant alloys to carbon-steel pipes. Because the cladding can…
A company in Hamburg, Germany had been using a 20-m3 mixing silo with internal pipe auger for 20 years. By replacing the pipe auger (photo, left) with an open mixing screw with special segments (photo, right), the company gained a…
One of the current methods for dealing with oil spills is through the use of dispersants. These dispersants, however, break oil into small globules that sink into the water, spreading the oil into a wider area, and they have toxic…
With the newly developed, high-precision 4090 pneumatic volume booster it is possible to amplify the air strength of the set point signal from the positioner to the actuator such that these control valves (depending on the nominal valve size)…
