New Peristaltic Pumps for Industrial Gas Analysis

New Peristaltic Pumps for Industrial Gas Analysis

In many areas of science and industry flexible tube pumps, better known as peristaltic pumps, are employed for the transportation of fluids. One of the outstanding applications in gas analysis is the discharge of condensate removed from the sample gas stream by a chiller. The flexible tube pump features a steady forward flow, without check valves, regardless of pressure variations within the system and prevents any ingression of ambient gas into the loop.

Extractive gas analysis tends to be utilised in application areas in which standardised conditioning systems are the first choice. These systems will usually consist of 19” racks, cabinets or even portable solutions. The technology for extractive gas analysis has been well established for a long time therefore the essential ingredients to produce reliable analysis results remain the same. Consequently, the installation of reliable and powerful components is paramount. For efficient condensate removal from the sample gas, semi conductive Peltier elements are broadly used as the chilling device.

The head of Bühler’s pumps include a bellow which is machined entirely from a single piece of PTFE for maximum durability. The pump is also extremely resistant to corrosion. The pump head can be easily adjusted upside down which allows wet sample gas to be transported. Pumps with extended drives are also available. These pumps house the head inside a heated cabinet, whilst the electric motor is mounted on an exterior extended drive shaft.

Zirconia oxyde sensors have been proven reliable in numerous applications to analyse or detect oxygen in flue gases or other process applications.

The advantage of these sensors is their high resistance against temperature variations and high gas temperatures. By placing the sensors directly in to (in-situ) or adjacent to the gas stream (close-coupled) very short reaction times can be obtained.
