The NF5 self-priming diaphragm pump handles air, gases, and liquids while simultaneously creating a vacuum. Measuring only 1.7
3 0.8 3 1.0 in., the unit is among the world's smallest diaphragm liquid pumps. The NF5 incorporates new cavitation-resistant diaphragm technology along with the latest valve design to produce 50 ml/min flow, 12-ft water suction, and 15-psig discharge. A 6-Vdc motor provides power. The low-cost pumps are suitable for analyzers, environmental samplers, ink-jet printers, and cooling-loop recirculation, as well as portable instruments where low current consumption, minimal noise, small dead-space volume, and reliability are needed.
