New BLDC Diaphragm Pump Features High Suction Speed in Low Vacuum


KNF's latest oil-free diaphragm pump, the Model N940.5APP features excellent suction speed at low absolute pressures in a compact, 4-stage package. A series of technical innovations include a diaphragm stabilization system, adjustable flow rate via potentiometer or external controller, and mutiple-voltage power capability. Rated at 50 LPM free-flow, it can achieve 1.5 mbar absolute end vacuum, with exceptional flow at lower pressures. This pump is very quiet and cool running, utilizing either an IP-54 AC motor, or an efficient brushless DC motor that features remote speed control capability. This allows instrumentation to determine pump performance based on demand or other criterion. A high level of gas-tightness is achieved, approximately 6 x 10-3 mbar x l/s. Typical applications are in the fields of analytical chemistry, medicine and semiconductor production technologies. The N940 also supports turbomolecular systems as roughing pumps.
