Vacuum pump VRD-48
Constantly pursuing on highest technology norms, Value's VRD series vacuum pump reached new highest level: integrated cylinder structure and innovative oil circulation system results in super stability; auto anti-sucking back valve and two shifts gas ballast makes best reliability. Perfect combination of technology and aesthetics helps to become classic.
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 from oil pollution when pump stops running and needs to be easily restarted.
Forced oil pump and constant pressure oil supply mechanism ensures stable running of the pump.
Less components are used, easy to maintain and repair.
