Product Overview
The VALUE VRD-8 Dual-Stage Rotary Vane Vacuum Pump is an oil-sealed vacuum pump for laboratory, analytical and industrial applications that need high ultimate vacuum with low noise. It delivers 8 m³/h at 50Hz on a 230V single-phase supply.
An integrated cylinder structure, forced oil circulation and an automatic anti-suck-back valve give stable, reliable running. It works as a main pump for medium and low vacuum systems, or as a backing pump for Roots, diffusion and molecular pumps.
Key Features
- 8 m³/h at 50Hz: Dual-stage rotary vane design for low ultimate pressure.
- Integrated cylinder structure: Proven vane technology for stable, reliable performance.
- Forced lubrication: Built-in gear pump with constant-pressure oil supply, stable even at high suction pressure.
- Two-position gas ballast: Adjustable gas ballast handles water vapour and condensable vapours.
- Anti-suck-back valve: Automatically prevents oil flowing back into the vacuum system after shutdown.
- FKM seals: Improve corrosion resistance and reduce oil leakage.
- Air-cooled: Oil-circulation air cooling, no external water cooling needed.
- KF vacuum connections: KF16 intake and KF25 exhaust for standard vacuum fittings.
