1.Two-Shift adjustable gas ballast valve satisfies different requirements of condensable vapor(such as water vapor) to be exhausted out of pump in different processes.
2.Dual protection of oil anti-sucking back ensures vacuum system from oil pollution when pump stops running and needs to be easily restarted.
3.Forced oil circulation system consisted of oil pump and constant pressure oil supply mechanism ensures stable running of the pump.
4. Less components are used, easy to maintain and repair.
