Edwards RV8 Rotary Vane Dual Stage Mechanical Vacuum Pump

• High reliability – generous lubrication of moving parts. Safe process and systems – fast acting inlet valve for best in class anti‑suck back protection.
• Configured to meet your vacuum needs – mode selector and two position gas ballast. No unplanned downtime – designed for easy maintenance.
• Better work environment – quiet running and intrusive frequencies minimised. Two position gas ballast allows either 60 g/hr or a class leading 220 g/hr (290 g/hr on RV12) of water vapour to be handled. Universal motor to cover the widest possible voltage and frequency range from a single variant.
• Smooth controlled inlet valve opening by oil pressure to eliminate pressure surges. Rapid closing inlet valve within 0.4 seconds of pump stopping.
• Pump oil is not included, please purchase the pump oil separately.Recommended oil:Ultragrade 19(Not inculded)

The RV series of small oil sealed rotary vane pumps deliver excellent ultimate vacuum pressure, high pumping speeds and superior vapour handling capabilities with quiet operation. With over 300,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. All RV pumps are approved to UL and CSA standards by an external test house and feature our unique mode selector switch, meaning one model is suitable for both high vacuum or high throughput applications.
