Laboratory vacuum pump N 920 G

membraneoil-free

Clean, oil-free diaphragm vacuum pumps of the N920 series are popular in laboratories for a wide range of appli- cations. They pump and evacuate without contaminating the medium. The high-performance N920 vacuum pumps are ideally suited for all applications that need high suction power yet low absolute pressures. A number of technical innovations, including a diaphragm stabilization system, enables stronc suction performance, especially in the low vacuum range. An integrated potentiometer makes it easy to select the desired pumping rate by selecting the appropriate speed, so the pump can adapt to the requirements of a particular process. An analog signal input for external control is availa- ble as an option.
