Micro Swing Piston Pump NPK 03

High pressure performance, in a compact size

The NPK 03 micro swing piston gas pump generates high operating pressures with low noise and minimal vibration.

The NPK 03 features high operating pressures to 80 psig, a free flow up to 3 L/min, and vacuum to 22.5 in. Hg. With low vibration, minimal noise level, high operating pressure, and compact size, the KNF NPK 03 micro swing piston gas pump is ideal for a number of applications, including:

  • medical point-of-care devices
  • DNA/RNA extraction instruments and nebulizers for the medical industry
  • coffee machines and milk foamers in the food industry
  • pulsation dampers in the print industry
  • elemental analysis nebulizers in the laboratory industry
  • other applications with demand for high pressure within limited installations space.

This small yet durable pump also offers a brushless 4-wire motor option which provides the ability to regulate pump flow by controlling the motor speed via PWM or control voltage. Configurations and performance data are provided below:
