Diffusion pumps become more energy efficient
This company has significantly reduced the energy consumption of the established DIP and newly developed DIJ diffusion pump series, with the aid of intelligent technologies and innovations. The new DIJ family (photo) features an optimized housing design, offering connections for both ANSI flange and ISO flange components, as well as various electrical connection variants. The new five-stage nozzle system of the DIJ series has been especially improved for the pressure range from 10–2 to 10–3 mbar. Through design changes and modern control elements the energy consumption of the diffusion pumps was reduced by an average of more than 30% — without sacrificing performance, the company says. — Leybold GmbH, Cologne, Germany

Transferring pure solvents in the semiconductor industry
The Futur S/SH air-operated diaphragm pump (AODP) series is now available in 316 stainless steel with high surface finish (photo) for the transfer of pure solvents in the semiconductor industry. Futur S/SH Series pumps are cleaned several times, then assembled and tested in a cleanroom line before being released for delivery. Futur S/SH Series pumps incorporate a straight-through flow pattern with only one wetted housing part, while the air-control system and the air chambers are located in the side housings. This design ensures that only one part of the housing comes into contact with the liquid, reducing the number of flow bends, minimizing the surface area, eliminating sliding parts in the product chambers and making it possible to eliminate the gaskets. The pumps are available in two sizes: 20 and 50 L/min. — Almatec Maschinenbau GmbH, Kamp-Lintfort, Germany
