The transportation of sample gas in sample conditioning systems requires very reliable sample pumps. Of course, the sample gas should have an equal and steady flow, but very often the corrosive nature of the gas and the presence of condensation form the real task for the pump.
The sample pumps are equipped with a bellow made of solid PTFE which has proven its reliability and long lifetime in numerous applications. If the pump head is pointed downwards the pump is able to pump sample gas with condensate contents.
A special flange design makes the P2.4 and P2.84 pumps suitable for hot applications i.e. the flange is designed of two parts. One part – carrying the pump head – can be installed into a heated cabinet and the other part – carrying the electrical motor – is flanged to the outside of the cabinet keeping the motor in ambient conditions.
