The latest KNF micro swing piston gas pump NPK 03 generates a high maximum operating pressure of 80 psig, with up to 3 L/min free flow and 22.5 in Hg vacuum. All this in a compact size for a great performance/size ratio. The brushless DC 4-wire motor option provides the ability to regulate pump flow by controlling motor speed via PWM or control voltage. Low vibration and noise level at high operating pressure makes NPK 03 ideal for applications such as nebulizers, point-of-care DNA/RNA extraction instruments, pressure-over-liquid lab-on-a-chip applications, printer pulsation dampers, coffee and milk frothers, and other applications with demand for high pressure with limited installation space.
