KNF’s NPK 012 offers a compact vacuum/pressure pump for portable devices.
KNF introduced its NPK 012 oil-free swing-piston pump that measures 103mm long and weighs 600g. The vacuum version of the pump reaches 25.8in.Hg (140 mbar abs), has a maximum flow rate of 13.5L/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.
