Edwards E2M0.7 Two-Stage Rotary Vane Vacuum Pump, 0.5cfm

The Edwards E2M series are rugged, oil-sealed, two-stage rotary vane pumps designed for dependable performance in laboratory and industrial environments. With compact footprints, quiet operation, and advanced lubrication circuits, EM pumps deliver excellent ultimate pressure and stable throughput for instruments, R&D benches, and light production.
Models such as the E2M0.7–E2M2.5 and E2M18/28 are ideal turbomolecular backing pumps for scientific applications, while E2M18/28, E2M40/80, and E2M175/275 provide robust solutions for demanding industrial processes. A full range of accessories (gas ballast, inlet/outlet filters, cables) lets you tailor the pump to your specific duty.
This listing highlights the E2M0.7 : DN 10 ISO-KF inlet, 0.56 CFM @60 Hz, 2.25 mTorr ultimate, 43 dB(A) noise, forced-air cooling, and IEC C14 power inlet.

Ships without a regional mains power cable. Select the correct cable from accessories. Use appropriate oil (Edwards 45). Verify compatibility with your process gases.
Two-Stage Oil-Sealed 0.56 CFM @60 Hz 2.25 mTorr Ultimate Quiet 43 dB(A)
Reliable performance: Advanced lubrication circuit and robust cast-iron internals for long service life.
Vapor handling: Gas ballast valve increases water-vapor tolerance and reduces condensation in the oil.

FAQ

What is a two-stage rotary vane pump?

A two-stage oil-sealed rotary vane pump uses two pumping stages in series to achieve lower ultimate pressure than single-stage designs, making it ideal as a backing pump for turbomolecular systems and general vacuum duties.
Is the E2M0.7 suitable as a turbo backing pump?

Yes. The E2M0.7 provides stable base pressure (down to ~2.25 mTorr) with low vibration and compact size, commonly used to back small turbomolecular pumps in analytical and R&D setups.
Can it handle water vapor?

Yes. The integrated gas ballast increases water-vapor tolerance and helps prevent condensation; verify your process rates against the listed vapor capacity.
Does the pump include a power cable?

No. This product does not include a mains cable. Select the appropriate regional cable separately. Some variants may require hard-wiring—check the manual.
