The chemical process industries (CPI) are looking for ways to decrease and control costs, and mixing operations are not exempt from this belt tightening. But because mixing is vital to most chemical processes, it can’t be eliminated. As a…
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…
The Conterna (photo) is a continuous kneading and extrusion machine designed for processing highly viscous materials, such as plastic compounds with a high percentage of fillers. Besides plastics, the Conterna is also used in the food and chemical industry for…
The glass Mitos Micromixer Chip (photo) is designed for the rapid mixing of two or three fluid streams. Compatible with the Mitos four-way edge connector, this novel chip enables extremely rapid mixing across a wide range of flowrates. This chip…
Newly designed rotary valves for pneumatic conveying of granular products feature expanded tips at the ends of rotor blades to reduce air leakage. The valves have an increased number of blades, as well as redesigned air vents to help minimize…
Swagelok New software has recently been released for this firm’s welding system M200 power supply (photo) to deliver increased performance and an updated graphical interface. The portable M200 is easy to use and offers 200-A capability for orbital welding at…
ESAB Welding and Cutting Products Purox and Oxweld oxygen cylinder regulators (photo) have a patented design that suppresses internal forces from a cylinder explosion within the cylinder walls. The design minimizes risk of injury in the event of an explosion.…
Michael Smith Engineers The established range of Viking External Gear Pumps (photo) has been extended to include models that provide flows from as little as 0.2 L/min up to 760 L/min. Available from this firm, the SG range now includes…
Cartex GSDN bi-directional gas-lubricated seals can be used to standardize new centrifugal pumps or recondition existing pumps that have conventional stuffing-box packings or liquid-lubricated mechanical seals. The characteristic design feature of the Cartex Series is a seat and shaft sleeve…
The Mouvex SLC-Series eccentric-disk pumps are designed to self-compensate for mechanical wear and maintain consistent flow over time. With seal-less construction, low shear and agitation of the pumped product, the ability to run dry for up to five minutes and…
