Larger members for this family of small pumps

Michael Smith Engineers The established range of HNP positive displacement, internal-gear pumps has been expanded to include new, larger pumps and more drive options. The 11500 Series (photo) deliver output flows of 0.2–1,150 mL/min and differential pressures between 0–60 or…

A more efficient system for making compressed air

Specializing in energy-efficient systems for compressed air, this firm has developed systems that allow energy savings of the initial compressor-power consumption. As an example, a conventional compressor with nominal flowrate of 160,000 Nm3/h and a discharge pressure of 18.5 bars…

Three new, efficient progressive cavity pumps

Three new progressive cavity pumps are now available from this manufacturer: the Series C is designed for demanding duties in the pulp and paper, mining and minerals, and chemical industries; the Series D is designed for dosing applications; and the…

Improved throttling now available in more sizes

Emerson Process Management This firm has extended line sizes for the Fisher Control Disk valve (photo), which offers excellent throttling performance and is suitable for applications that involve fast processes and varying pressure drops. The valve’s control range is said…

Manufacture of this HDPE is environmentally friendly

Vestolen A Rely 5922R and 5924R are the first two grades of high-density polyethylene (HDPE) for piping that are manufactured in this company’s state-of-the-art facility in Germany, where their production places less stress on the environment by reducing air emissions,…

These Multistage Centrifugal Surface Pumping Systems are Suitable for High Pressure Applications

Building on downhole electric submersible-pump technology, the SPS (Surface Pumping System; photo, p. 32D-4) is a low-maintenance, cost-effective alternative to plunger (triplex, quintiplex), split-case centrifugal, high-speed centrifugal and canned vertical turbine pumps in a variety of industrial surface-fluid-movement applications. The…

Compact Reaction for Viscous Mixtures Offers Powerful Stirring

Viscous reaction mixtures often require more powerful stirring than can be achieved with magnetic stirrers. The Vortex stirrer system (photo) converts a single overhead stirrer into a powerful three-position parallel stirrer combined with a multiple heating block. The combination of…

These CPVC Pipes are Now Available in Large Diameters

Touted as the first chlorinated polyvinyl chloride (CPVC) pipe commercially available in large diameters, this firm’s line of rigid, extruded industrial-CPVC pipe now includes 18-, 20-, and 24-in. dia. sizes at ANSI Schedule 40 and 80 dimensions. Like the rest…

This Anti-Surge Compressor Controller has an Built-in HMI

This firm has introduced its first stand-alone compressor anti-surge controller with a built-in color HMI (human machine interface) display. The Em-400 HMI displays a live compressor surge map for easy viewing of compressor performance. In addition to the live compressor…

Free software predicts control valve package performance

Nelprof control valve selection software Version 5.0 facilitates selection of the best control valve package quickly and accurately. It is used prior to installation to predict the performance of the control valve package as a part of the system. Version…
