Edwards RV12 Dual-Stage 8.4 CFM Vacuum Pump with Bellow & Fitting

Oil Rotary Vane Pumps Two-Stage

Rotary vane pumps are considered wet, positive displacement pumps, with the term “wet” denoting that the gases being pumped are exposed to oil. The significant characteristic of oil sealed rotary vane (OSRV) pumps is the use of oil as a sealant and coolant.

Two-stage rotary vane vacuum pumps use a two stage compression offering high pumping speeds combined with low ultimate pressure. They are widely used in industrial, chemical, pharmaceutical, and food industries.

RV Two Stage RVP

RV oil sealed pumps have been the industry standard rotary vane pump for laboratory applications for many years thanks to design features that make them low-cost to operate and maintain versus other rotary pumps.

With their unique mode selector, one pump can be used for both high throughput and high vacuum applications; self-centring mechanism, no dowels to set and can replace any component; high vapour pumping capability and broad range of accessories makes RV pumps the best long-term proposition for laboratory applications.

RV pumps are available with speeds ranging from 3 to 12 m3/hr. With 400,000 units produced, these pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications.
