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 .
