Edwards E2M18 Two Stage Rotary Vane Vacuum Pump – 12.1 CFM, 200-230/380-415V 3-Phase 50/60Hz (A36310940)
The Edwards E2M18 (part number A36310940) is a robust two-stage oil-sealed rotary vane vacuum pump from the industry-leading EM series. This universal 3-phase model is designed for laboratory and light industrial applications that demand reliable continuous-duty operation with three-phase power.
Featuring a pumping speed of 12.1 CFM (20.4 m³/h) at 60 Hz and an excellent ultimate vacuum of 1 × 10⁻³ mbar (7.4 × 10⁻⁴ Torr) without gas ballast, the E2M18 provides fast evacuation, superior vapor handling, and quiet performance. The versatile 3-phase motor supports 200-230/380-415V 3-ph 50 Hz or 200-230/460V 3-ph 60 Hz, making it suitable for facilities with three-phase electrical supply.
Its direct-drive design with flexible coupling, advanced lubrication system, and proven EM series engineering ensure long-term reliability and easy maintenance.
Key Features and Benefits
- Two-stage rotary vane design for deeper ultimate vacuum and excellent vapor tolerance
- High pumping speed of 12.1 CFM (20.4 m³/h) at 60 Hz
- Quiet operation at 57 dB(A)
- Universal 3-phase motor: 200-230/380-415V 50 Hz or 200-230/460V 60 Hz

Why Choose the Edwards E2M18 3-Phase? The three-phase motor variant provides greater efficiency, higher starting torque, and better suitability for continuous or high-duty-cycle applications compared to single-phase models. The two-stage design achieves significantly lower ultimate pressure than single-stage pumps, making it the preferred choice when deeper vacuum is required while maintaining the EM series’ renowned quiet operation and reliability.
Applications
- Laboratory vacuum systems
- Mass spectrometry and analytical instruments
- Vacuum drying and degassing
- Vacuum ovens and freeze dryers
- Refrigeration and air conditioning service
- Light industrial processes and backing pumps
What's Included
- Edwards E2M18 Rotary Vane Vacuum Pump (A36310940)
- Ultragrade 19 vacuum pump oil (initial charge)
- NW25 centering ring and O-ring
Note: This pump is hard-wired in the electrical box — power cord / wiring is not included. For corrosive or aggressive vapor applications, consider the PFPE-prepared E2M18FX (A36325984) variant.
The Edwards E2M18 two-stage rotary vane vacuum pump (3-phase) is a trusted industry-standard solution that delivers consistent high performance, quiet operation, and long-term reliability in laboratory and light industrial environments.
