The Bühler Technologies P2.3 Sample Gas Pump is a high-performance diaphragm extraction pump engineered by Bühler Technologies GmbH (Germany)—a recognized global leader in sample gas conditioning systems. This pump is designed to reliably extract and convey sample gas from sampling probes through conditioning lines to gas analyzers in continuous emission monitoring systems (CEMS).

The key advantage of the P2.3 model lies in its chemically inert pump head construction, manufactured from premium corrosion-resistant materials such as PTFE, PVDF, or 1.4571 (316Ti) Stainless Steel combined with a PTFE-coated diaphragm. This ensures complete protection against aggressive gases including SO2, SO3, NOx, HCl, HF, H2S, CO, CO2, and organic solvent vapors without altering the sample composition.

Featuring low vibration emissions, quiet running performance, and smooth flow delivery, the Bühler P2.3 is built for continuous 24/7 duty in demanding industrial plant environments. The straightforward pump head design allows fast and easy maintenance, permitting quick diaphragm and valve replacements directly on-site to minimize system downtime.
