Refurbished Rotary Vane Pumps

All New Edwards RV 12 pumps are significantly quieter – noise levels of 48 dBA 50Hz are typically half the noise of a conventional pump and have been achieved by extensive work on the drive train and motor.

New Edwards RV-12 P/N A655-01-906 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 unrivalled opportunity to select the optimum pumping performance without compromising the application.

Edwards Vacuum pump In its high vacuum mode, the RV 12 vacuum pump is ideal for analytical instruments, electron microscopes, physics research, backing turbo pumps and leak detection applications. Configure the same RV-12 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.

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.

Edwards RV12 vacuum pumps have become the industry standard for scientific primary pumping applications. Edwards 12 RV pumps are uniquely capable of delivering high or low throughputs with high ultimate vacuum. This, combined with ultra-low noise levels, makes them ideal for a wide range of applications including GCMS and other small bench top type applications.

Edwards Vacuum RV 12 Rotary Vane Pump Features:

– 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.

The Edwards E2M18 Rotary Vane Pump is a vacuum pump that has a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open.

You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.

The EM Vacuum Pump Series range of oil‑sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single‑phase or three‑phase (four pole) motor.

Edwards E2M 18 Dual Stage Rotary Vane Pump Features:

– The pump is designed for reliable, long‑term operation.
– Thermal overload device prevents overheating (single phase only).
– The drive is provided through a flexible coupling by a single‑phase or three‑phase (four pole) motor.
– The motors are totally enclosed and are cooled by the motor cooling fan.
– Full height O ring sealed oil sight glass for easy checking of oil level and condition.
– Large sight glass and operating oil range.
– IE3 energy efficient 3 phase motor used with E2M28.
