KNF (Trenton, NJ) introduces a new oil-free swing-piston pump that addresses the demand for a more compact, high performance, and economical solution for portable devices. At 103 mm in length, the new NPK 012 is 30% shorter than other models in its performance class. Even more impressive, the new pump’s weight is a light 600 g, under-cutting other models by half.
Although small, the NPK 012 offers high levels of both vacuum and pressure performance. The vacuum version reaches 25.8 inHg (140 mbar abs), has a maximum flow rate of 13.5 L/min, and can deliver 15 psig continuously. The pressure version delivers up to 36 psig (2.5 bar) of continuous positive pressure, and up to 72 psig (5 bar) during intermittent operation. Both versions can start up against the full vacuum and pressure range, and the brushless DC motor provides excellent custom-fit speed control with low energy consumption.
