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