At 1.6 inches long, the NF5 allows for locating it closer to the pumping function. Featuring a flow rate of 50 ml/min, it develops a suction height of 13 ft water with a discharge pressure of 15 psig. The pump is maintenance-free and uses corrosion-resistant Ryton/EPDM envelope which handles neutral solutions, mild acids, inks, caustics, and other harsh materials. It is self-priming and can run dry indefinitely. The NF5 replaces peristaltic pumps which can exhibit an inconsistent flow rate over time and eventual tubing failure.
