Even in explosive systems in the chemical industry,
petrochemistry or biochemistry, gas analysis is key for safe
operation. Many of the analysis processes used in these fields
require extracting and special conditioning of the sample gas.
Sample gas pumps convey the sample gas from the sampling
point to the conditioning system. The main item in these
specially designed pumps is the PTFE single-piece bellow.
Combined with the pump head, also single-piece, this solution
provides high resistance against particularly aggressive
sample gas. Turning the pump head allows gas with
condensate to be conveyed without a problem.
There are several different models with separate drive,
depending on the requirements. These versions allow the
installation of a coupling flange to install the pump heads
inside heated housings away from the motor whilst the motor
remains outside the housing.
The series are available for various EX hazard and
classification zones with flow rates up to 800 L/h.
