- Dual-Stage Rotary Vane Vacuum Pump
- Excellent performance,Integral pump structure,require higher accuracy;Procen vanes technology,makes the performance more stble;Ensure the pump system with higher reliability.
- Excellent heat dissipation,Air-cooled struture,without external water cooling system,reduce the instanllation and mainantence costs.
- Forced lubrication,Built-in gear pump and constant pressure oil supply mechanism forced oil supply,ensure the stable and reliable operation under high suction pressure.
- Two-shift adjustable gas ballast valve,Meet customers vacuum requirement and steam handling capacity.
- FKM seals,Improve corrosion resistance and solve the problem of oil leakage.
- Double anti-suck back structure,Automaticly prevent oil suck back,and more reliably protects your vacuum system from oil contanmination after vacuum pump shutdown.
- High quality oil mist filter,Effecively filter oil mist,protect the environment clean.
