Abstract (en)
[origin: US4790730A] Deposits and corrosion are to be avoided in a heatable diaphragm pump for smoke gases which are to be analyzed. A heatable pump head comprises a diaphragm chamber which is closed by a diaphragm. The diaphragm is driven by a motor through a connecting rod. The connecting rod is heated by controlled heating means and a temperature sensor. Transmission of measuring signals from the temperature sensor to a controller and the power supply to the heating means is permitted through U-shaped leaf springs.
