A wet pump uses low vapor pressure oil in the pumping mechanism. A diffusion pump, for example, uses oil vapor flow as the pumping mechanism while a rotary vane pump uses oil to lubricate and seal sliding joints between vanes and casing. So, in any wet pump, oil liquid and vapor coexist in the pumps vacuum volume. A dry pump has no gas sealing .
