A PTFE diaphragm permits compact construction of this diaphragm pump, and offers cost savings for high-pressure applications. A patented pressure-supported diaphragm-fixation system is used, so that the fixation is structurally prevented from expanding during the pressure stroke. No auxiliary seal…
This new air-atomizing nozzle enables the effective spraying of viscous fluids at very fine atomization but at low flowrates. The XA ER nozzle provides a full cone spray pattern for liquids with viscosity of 100 cP or more. The nozzle…
Available from this company, the Dickow magnetically coupled centrifugal pumps include the KM series, which handles capacities as high as 65 m3/h at heads up to 65 m. All KM Series pumps are magnetically coupled, so they are leak-free. Available…
The Type 3738 electronic valve position monitor is a contactless, magneto-resistive sensor system that works with a Namur signal in compliance with IEC 60947-5-6 and is powered by a two-wire supply. As a result, the positioner can replace existing solenoid…
The new generation of this company’s Embreak emulsion breakers employs new chemistry designed for light- and medium-density crude petroleum. The products deliver optimal desalter performance, the company says, while reducing the generation of nonylphenol ethoxylates (NPE), a byproduct of emulsion…
Pfeiffer Vacuum Large pressure ranges and maximum compression ratios are the ideal site of operation for the gas-cooled roots pump OktaLine G. The pumping speed ranges from 250 to 12,000 m3/h, and is suited for low and medium vacuum, such…
This company has upgraded the 4-in. model of its NP Series sliding vane pump with optional electric heating. The completion of the 4-in size follows other sizes in the series with this option. Electric heating can be used in place…
As chemical processors continue their quest to process more with less equipment, they are seeking reactors capable of helping with this endeavor. For this reason, many are turning to continuous flow reactors because they provide scaleability and flexibility. However, vendors…
By immobilizing carbon nanotubes (CNTs) within polymer membrane pores, scientists at the New Jersey Institute of Technology (NJIT; Newark, N.J.; www.njit.edu) were able to significantly improve the efficiency of desalination via a membrane distillation process. Somenath Mitra and colleagues at…
Spider silk has many unique properties that make it suitable for applications such as coatings and medical products. As a protein, the silk is remarkably stable and is only destroyed physically or digested and recycled by the spider. However, an…
