KNF's N860 Series diaphragm vacuum pumps feature multi-port valves to tolerate condensation without damage
KNF N860 Series diaphragm vacuum pumps are designed to sample, transfer or evacuate air and gases. These compact and cool-running pumps can suit a variety of process, laboratory or OEM applications ranging from large-scale rotary evaporators and continuous/manifold filtration systems to process control sampling.
These pumps feature as standard 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 are designed to 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.
Pumps can be equipped with standard AC motors or explosion-proof AC versions for compliance with Class 1, Division 1, Groups C and D hazardous locations. Single- or doubled-headed pump options can also be specified. Wetted material choices range from economical aluminum heads and EPDM diaphragms to solid glass-filled PTFE heads and PTFE diaphragms, which offer higher resistance to corrosion and chemicals.
