Swing Piston Pumps
Flow rate (at atm. pressure)
Upgraded with Faster Installation
Since its introduction in 2019, KNF NPK 012 has been an ideal, affordable solution for applications requiring minimal vibration, low noise, compact size, and high performance.
With the 2021 release, the revised NPK 012 meets these requirements with faster installation. The new electrical connector speeds up the pump integration and protects the motor connection against reverse polarity.

Customizable Modular System
The patented KNF Modular System provides additional options for this carefully crafted swing piston pump. An optional pump housing cover is now available, offering better safety protection. Moreover, an optional base plate with a flexible bore pattern ensures easier mounting and compensates for vibrations.
Small yet Powerful
The NPK 012 builds up 2.5 bar continuous positive pressure and up to 5 bar during intermittent operation. The pump achieves an ultimate vacuum of up to 140 mbar absolute with a flow rate of up to 13.5 l/min.
This pump delivers such impressive performance with a maximum power consumption of just 43 W. Weighing 600 g only also makes it well-suited for handheld devices.
Additionally, based on long-term internal testing, the permissible media temperature range is now expanded to 60 °C / 140 °F.
