Edwards RV series

The Edwards RV series comprises powerful, oil-sealed rotary vane vacuum pumps for demanding applications in research, development and industry. They offer high pumping speed, good ultimate vacuum, high water vapour tolerance and quiet operation.

The pumps can be configured for different vacuum requirements and feature a two-stage gas ballast, a universal motor and a fast-closing inlet valve. A special mode selector allows the pump to be adapted to high vacuum applications or to applications with high gas throughput.

Typical fields of application are analytical instruments, laboratory vacuum, turbomolecular pumps, freeze drying and research and development. The proven design ensures high reliability, safe processes and low-maintenance operation.

Standard operating conditions and performance

Ambient temperature: +12 to +40 °C

Nominal pumping speed: approx. 3.3 to 12 m³/h (at 50 Hz), depending on the model

Achievable ultimate vacuum: down to approx. 2 × 10⁻³ mbar (absolute), depending on the version

Maximum permissible operating pressure: up to 500 mbar (absolute) in High Vacuum mode or up to 5000 mbar in High Throughput mode

Designed for oil-sealed, two-stage vacuum applications

Operating principle

The Edwards RV series works on the proven principle of two-stage, oil-sealed rotary vane vacuum technology. An eccentrically mounted rotor with vanes rotates inside the pump housing, creating continuously changing working chambers. The air drawn in is compressed as the volume of the working chambers decreases and is then expelled through the outlet.

The pump oil performs important functions for lubrication, sealing and heat dissipation and thus supports reliable and efficient pump operation. The two-stage design enables a high ultimate vacuum, while the integrated gas ballast system helps in handling condensable vapours.

The RV series is characterised by its robust design, low noise and vibration levels and reliable performance. It is suitable for numerous applications in industry, research and laboratories, in particular for processes that require stable and high vacuum performance.
