VRD series vacuum pump is a high speed, motor direct drive dual-stage oil sealed rotary vane pump. it is an basic equipment toobtain vacuum and can be used to pump inactive gas within the scope of low vacuum and a small amount of non-condensable gasThe pump is specially suitable for coating, refrigeration, freeze drying, sterlization, instruments analysis, leak detection equipment,neat treatment metallurgy, etc. lt can be used as a backing pump for roots pumps as well.
Product Feature
- Excellent performance:integral pump sirueture, require higher accuracy;Proven vanes technology,makes the performance more stalble;Ensure the pump system with higher reliability.
- Excellent heat dissipation:Air-cooled structure, without external water cooling system,reduce the installation and mainantence costs.
- Forced lubrication:Bullit-in gear pump and constant pressure supply mechanism forced oil supply.ensure the stable and reliable operalion under high suction pressure.
- Two-shift adjustable gas ballast valve:Meet customer's 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 contamination aller vacuum pump shutdown.
- High quality oil mist filter (for option):Effectively filter oil mist, protect the environment clean.
