Ball valves with three seating options — graphite, metal and soft
Ultra-Seal Series 300 ball valves are two-piece, full-bore, flanged, seat-supported ball valves designed in accordance with ASME B16.34 and ISO 14313/API 6D standards. The series offers three seating options — graphite, metal and PTFE (polytetrafluoroethylene) soft seat — which allows…
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…
Routine maintenance is simplified with this mixer drive
The UniFirst 4040 mixer drive (photo) is designed to provide trouble-free operation while lowering maintenance costs. Routine maintenance is simplified with fewer parts, easy accessibility and standard components. Additional features include: rugged design withstands corrosive and caustic environments, high temperatures,…
A large globe valve for high-capacity control
This firm’s response to the increasing demand for high capacity globe-style control valves, especially as anti-surge valve on turbo compressors, is the Ecotrol Control Valve (photo) with size 24 in. (DN 600). With a standard body material of carbon and…
A wide range of well-known and new pumps exhibited here
Formed by its parent company, Dover Corp., in 2008, this firm combines the following companies into a cohesive pump organization with a broad array of pump technologies: Wilden, Blackmer, Mouvex-Blackmer, Griswold and Neptune. At Achema, the organization will be debuting…
Eccentric disc pumps compensate for mechanical wear
On display for the first time at Achema 2009, last month, SLC-Series eccentric disc pumps (pohto) offer lower ongoing operations and maintenance costs in the transfer of various chemicals due to superior volumetric efficiencies. Unlike gear and lobe pumps that…
