Diaphragm Vacuum Pumps

July 3, 2012

KNF N860 Series diaphragm vacuum pumps introduce ideal solutions to sample, transfer or evacuate air and gases. These compact and cool-running pumps benefit from a patented structured diaphragm promoting optimized pneumatic performance and long service life. The pumps can suit a wide variety of process, laboratory or OEM applications ranging from large-scale rotary evaporators and continuous/manifold filtration systems to process control sampling. Customization capabilities expand their application potential to many other areas. These pumps feature as standard specially engineered multi-port valves to tolerate condensation without damage, perform oil-free transfer with uncontaminated flow and minimal maintenance and run quietly with low vibration. They can achieve enhanced gas tightness with leak rates as low as 6 x 10-3 mbar L/s, deep vacuum potential of 2 mbar and flows as high as 110 L/min.
