Samson Controls The air output capacity required to achieve fast positioning in large actuators (diaphragm areas of 1,400–2,800 cm2) is too much for normal positioners, and so positioning accuracy can be compromised. A solution to this problem is a control-valve…
AtlasCopco Compessors A prominent design feature of ZS Series blowers (photo) is their application of rotary screw compression technology. The rotary screw concept helps the blower to operate at efficiencies 35–40% higher than traditional tri-lobe blowers at a compression ratio…
The three-chambered configuration of the Flojet Triplex Series high-pressure, self-priming pump operates at flowrates up to 1.4 gal/min (5.3 L/min) and operating pressures up to 150 psi (10.3 bar). Their molded diaphragms virtually eliminate potential leakage paths, says the company.…
These new atomizing spray nozzles generate a precise 50-deg hollow-cone spray pattern to ensure controlled atomization in a compact package. The nozzles are available in both airless and air-assisted styles, and are suitable for critical spray applications. The airless versions…
The new AmaRoc mixer stand was developed as a secure and durable foundation for the firm’s AmaProp submersible mixers with their large (up to 2.5-m dia.) propellers. The propeller is capable of absorbing all forces generated by the mixer and…
Among the new innovations launched at the K-Show are Edgetek AM Flame Retardant, Non-Halogen compounds, a new line of RoHS-compliant, high-temperature polyamide compounds. Configured for easy processing, these compounds are suitable for molding thin-walled parts in multi-cavity tools for improved…
KSB This firm recently delivered three specially designed, submersible borehole pumps (photo) for discharging crude oil from an underground rock cavern in Sweden. The three pumps are equipped with a 700 kW motor and are operated at…
Available in galvanized steel, stainless steel and brass, Nilos rings (photo, p. 64) safeguard ball and roller bearings from the corrosive effects of abrasive particles and debris. The rings can be specified in a wide range of sizes to seal…
The HiPace line of compact, powerful turbopumps (photo) offers pumping speeds of 10 to 700 L/s. The pumps feature an improved rotor design that give both high pumping speeds and high gas throughputs, along with very good compression for light…
This firm specializes in the fabrication of stainless-steel process equipment for the chemical and pharmaceutical industries. For example, it has designed and built a 22-m3 reactor vessel with the following features: double-coated cooling, double mixer; distribution of nitrogen, diffuser for…
