The Bühler Sample Gas Pumps P2.x ATEX transports gas from the sampling point to the pretreatment system. We integrate a single-piece PTFE bellow and pump head to withstand highly aggressive gases and moisture, and when you rotate the pump head, the system seamlessly handles condensate-laden gas without interruption.

Choose from direct-drive models or separate-motor versions—with coupling flanges that let you safely position pump heads inside heated housings while keeping motors outside.

We designed the line to meet a wide range of zone requirements (Safe Area, ATEX Zone 1/2, FM Class I Div. 2), and deliver flow rates up to 700 L/h for flexible, high-performance sampling.
