KNF Micro Swing Piston Pump - NPK 012

Highly Performant. Now Even Smaller.

With the release of the all-new NPK 012 swing piston pump, KNF again offers an affordable, lightweight and high-performance solution for the medical device industry.

Perfect for Handheld Devices

The NPK 012 offers high levels of both vacuum and pressure despite being small in size. At 103 mm in length, the new NPK 012 is 30% shorter than previous models in its performance class. Moreover, by weighing as light as 600 g, the pump undercuts others by 50%, making it perfect for mounting in handheld devices.

The pressure version, NPK 012 PR, delivers up to 2.5 bar of continuous positive pressure, and up to 5 bar during intermittent operation. The BLDC motor inside provides excellent custom-fit speed control with a low energy consumption of just 43 W. Furthermore, the pump can start up against the full pressure.

Ideal for Various Applications

This carefully crafted swing piston pump is well-suited for applications requiring minimal vibration, low level of noise, compact size and high performance, including medical inhalation therapy devices; sprayers (disinfection, scent dispensing, crop protection); pick-and-place vacuum equipment; and pneumatic actuators.
