Sample Gas Pumps

Solid PTFE bellowpumps for transporting sample gas

Sample gas analysis systems require pumps when the process pressure is not sufficient to transport an adequate volume of sample gas to the analysers reliably. The frequent corrosive and aggressive nature of the sample gas demands special properties of the material in contact with the media. The pumps can also transport potential condensate.

Bellows pumps have proven to be particularly suitable for this challenging application. These sample gas pumps feature a PTFE bellow which has been proven reliable and durable in high quantities. The comprehensive range of flow rates and options meets a vast range of applications both in emission monitoring and process analysis.
