EDWARDS RV3 Rotary Vane Vacuum Pump for Sale

Edwards 3 Rotary Vane Vacuum Pump Model: RV3 A65201903

**This unit has been tested to specifications. Vacuum pressure at 1 microns (Pressure gauge not included). Has slight cosmetic blemishes from normal use. See photos for further details.

The Edwards RV3 rotary vane mechanical vacuum pump delivers excellent ultimate vacuum pressure, high pumping speeds and superior vapor handling capabilities with quiet operation. These pumps offer proven performance that sets the industry standard for R&D and scientific pumping applications. RV pumps are quiet. Noise levels of 48 dBA 50Hz have been achieved by extensive work on the pump design, drive train and motor. The pumps have the unique ability to deliver excellent ultimate vacuum in both high vacuum and high throughput modes with or without gas ballast. This gives the user an unrivaled opportunity to select the optimum pumping performance without compromising the application.

The simple to use mode selector and accessible, three-position gas ballast control allow the pump to be reconfigured at any time, even when the pump is running. In high vacuum mode, the RV pump is ideal for analytical instruments, electron microscopes, physics research, backing turbo pumps and leak detection applications. Configure the same pump in the high throughput mode, and it becomes suitable for distillation, laboratory furnaces, backing vapor pumps, solvent concentration, freeze drying and other drying applications.

Features:
High reliability generous lubrication of moving parts.
Safe process and systems fast acting inlet valve for best in class antisuck back protection.
Configured to meet your vacuum needs mode selector and three position gas ballast
No unplanned downtime designed for easy maintenance.
Better work environment quiet running and intrusive frequencies minimised.
Three 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 motorto 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.
Large, clearly marked, easily accessible controls
Operate at quiet 48dBA
Easy to use and service (require no special tools)
Fast-acting inlet valve prevents oil and gas suckback in the event of power or oil pressure loss
NW25 inlet/outlet connections
