Condensable Components in the Medium to Be Pumped

If the condensable components are contained in the pumped flow, then these, depending on the material properties, condense during contact with the operating liquid. The chamber becoming open due to the condensation is filled up by gas flowing in, so that an increased suction capacity is to be denoted as 

In the assumed case of the position of equilibrium and in consideration of the Dalton law Ps = Pj) l s suction capacity results from Eq. (3.6)
