N920

KNF's new N920 series pump features excellent pumping speed at low vacuum levels. Interconnections are an integral part of the three-stage head and improve leak-tightness.
Input power features a universal (90-264VAC, 50-60Hz) AC input or a speed-controlled brushless-DC motor. It is gas tight to 6x10-3 mbar x l/s specifications.
N940

KNF's new N940 series pump features excellent pumping speed at low vacuum levels using KNF's diaphragm stabilization system.
Input power is a universal (90-264VAC, 50-60Hz) speed-controlled brushless-DC motor, or an IP-54 AC motor. It is gas tight to 6x10-3 mbar x l/s specifications.

KNF's Model UN813.4ANI pump shown with a logic and speed-controlled, brushless DC motor generates <0.5 mbar (<0.375Torr) of dry, oil-free vacuum using only four heads. These pumps represent our latest innovations, including logic-controlled speed controls.

NOTES: Standard continuous performance ratings listed on this KNF website and on KNF datasheets are based on technical data and test results of nominal units at sea level, measured with an ambient temperature of 70°F (21°C), and nominal electrical supply as listed above, and are for reference only.Multiple-head models, different performance models, cost-effective OEM modifications, and a variety of motor options and different materials of construction are also available. Certified drawings are available upon request. Specifications subject to change without notice. You should always check corrosion resistance charts for compatibility with the medium you intend to pump.
