The N920 Series diaphragm vacuum pumps uniquely promote optimized suction speed, especially in the low-vacuum range.

KNF (Trenton, NJ) N920 Series diaphragm vacuum pumps to transfer, evacuate, or compress air, gases, and vapors have been engineered to deliver higher flow performance at low absolute vacuum levels. Their innovative diaphragm stabilization system uniquely promotes optimized suction speed, especially in the low-vacuum range.  These pumps ideally suit a wide range of analysis, monitoring, and production applications and also can support turbomolecular systems as roughing or backing solutions. Features include:

• A high level of gas tightness to 6 x 10-3 mbar l/s.
• Flow rates up to 21 l/m, vacuum of 1.5 mbar absolute, and maximum continuous pressure of 0.5 bar g.
• Pumps offered in 3-head OEM installation models with multi-voltage power supply input. 
• A universal 90-264 VAC, 50-60 Hz, AC input or brush-commutated DC or brushless DC (BLDC) motor.
• A smooth, molded diaphragm that minimizes the dead volume in the pumping chamber for improved end-vacuum.
• A manifold block head that eliminates the need for external connections to enhance leak-tightness.
