Edwards RV12 Two-Stage Rotary Vane Vacuum Pump

Product details

Choosing RV12 Two-Stage Rotary Vane Vacuum Pump

The Edwards RV12 is a two-stage oil-sealed pump for laboratory vacuum, analytical equipment and suitable turbomolecular backing duties. It delivers 12 m³/h peak pumping speed at 50 Hz, with selectable high-vacuum and high-throughput modes for different gas loads.

The RV12 provides the highest 50 Hz pumping speed in this RV group and the highest listed gas-ballast-II water-vapour capacity, 290 g/h.

Key specifications

Ultimate pressure is measured under the manufacturer’s test conditions and is not a guaranteed chamber pressure. The PFPE-prepared rating is 0.02 mbar rather than the 0.002 mbar hydrocarbon-oil value. Water-vapour handling depends on warm-up, mode, gas ballast and operating conditions. Keep the original brochure conditions with each figure.

High vacuum and high throughput modes

The mode selector changes the operating envelope: high-vacuum mode supports lower ultimate pressure, while high-throughput mode permits higher continuous inlet pressure. The brochure gives 0.03 mbar ultimate pressure in high-throughput mode. Pumping down a chamber from atmosphere does not mean continuous operation at atmospheric inlet pressure is permitted.

Electrical and oil configuration

For a UK single-phase installation, request the 230 V setting and the separately selected UK three-pin cord set A50505000. Three-phase versions use their own wiring and protection requirements. Standard ULTRAGRADE configurations are supplied with an initial oil charge according to the brochure. PFPE-prepared pumps require separately ordered PFPE fluid; do not treat changing oil as converting a standard pump into a PFPE-prepared build.

Accessories and maintenance

Specify inlet protection, foreline trapping, exhaust mist filtration and any oil-return arrangement for the application. The brochure lists FL20K foreline traps, EMF10/EMF20 mist filters, vibration isolators and acoustic enclosures as accessories; an illustration is not an included-equipment list. Confirm filter sizing and oil-return compatibility for the selected gas-ballast duty.

New and reconditioned equipment

This page covers new RV12 selection. Girovac also retains a separate reconditioned RV12 listing; condition, included equipment and availability must be confirmed for that unit.
