The transportation of sample gas in sample conditioning systems requires reliable sample pumps. The corrosive nature of the gas and the potential of condensate formation are the real challenges for any pump. These sample pump are equipped with a bellows made from solid PTFE. This design has demonstrated the highest reliability and long lifetime in numerous applications. Designed specifically for harsh gas applications that have entrained liquids present or where condensate is expected to form, it is recommended that the pump head be pointed downwards to accomodate draining of these liquids. The arrangement of two identical pump heads attached to a double shaft motor provides an economic solution for analyzer systems with two independent gas streams to be drawn for the process. For applications which require fast response times, the flow rate of the P4.83 could be increased by combining the two parallel streams.
