The Bühler Technologies P1.1 Sample Gas Pump is a premium diaphragm pump specifically engineered by Bühler Technologies GmbH (Germany)—a 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 core advantage of the P1.1 model lies in its chemically inert pump head construction, available in high-grade materials such as PTFE, PVDF, or 1.4571 (316Ti) Stainless Steel combined with a PTFE-coated diaphragm. This ensures exceptional resistance against aggressive gases including SO2, SO3, NOx, HCl, HF, CO, CO2, and solvent vapors without altering the sample composition.

Featuring a compact footprint, low noise emission, and smooth flow delivery, the Bühler P1.1 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 to minimize system downtime.
