【Back】 VRD Dual Stage Vacuum Pumps
Product:VRD-M
H2O2 Plasma Sterilizers Pump

Features:

- Stainless spring is used for a better corrosion resistance.

- 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.
- Dual protection of oil anti-suck 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.
