KNF unveiled its N 952 oil-free vacuum pump for use in analytical chemistry systems and as a pre-vacuum option for turbopumps. With an ultimate vacuum of up to 1.5 mbar abs. and a free-flow of up to 36 l/min, the N 952 features four pump heads that can be connected in series or parallel as well as other combinations dependung on process requirements. The pump is supported by a generation of in-house developed and produced brushless DC motors. Like all in-house developed KNF BLDC motors of the digital customization series, the new generation can be controlled analog, via PWM or digitally. The chemically resistant N 952 with brushless DC motor is available in both 24 V or with an integrated AC/DC converter.
