Sample Gas Pump P 2.2-Ex § robust and reliable design

Sample Gas Pump
P 2.2-Ex
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 condensate form the real task for the pump.
§ robust and reliable design
The standard version of the P 2.2 Ex sample pump is
equipped with an bellow made of solid PTFE which has
proven his reliability and long lifetime in numerous
applications.
§ pumps condensate containing gas
If the pump head is pointed downwards the pump is able
to pump sample gas with condensate contents.
The pump employs explosion proove motors and is
suitable for class 1.
§ easy to change valves
§ bellow made of a solid piece
§ low noise emission
§ with support console
§ optional adjustable bypass valve
§ high life expectancy
For easy installation a support console with dampers is
included .
