The pump adopts gas ballast valve which can well rule out water vapor. The gas ballast can fill the air for exhaust compartment, which can reduce vapor ultimate partial pressure, the vapor will be removed. So the gas ballast can well remove the vapor in the pump oil, which can prolong the pump service time and prevent the mix for oil and water vapor.
