Edwards E2M18 Two Stage Rotary Vane Vacuum Pump – 12.1 CFM, 200-230/380-415V 3-Phase (A36310940)
The Edwards E2M18 (part number A36310940) is a high-performance two-stage oil-sealed rotary vane vacuum pump from the reliable EM series. This 3-phase version is designed for laboratory and light industrial applications that require robust, continuous-duty operation with higher power availability.
With 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 delivers fast pump-down times, quiet running, and superior vapor handling. The universal 3-phase motor supports 200-230/380-415V 3-ph 50 Hz or 200-230/460V 3-ph 60 Hz, making it ideal for facilities with three-phase power.
This direct-drive pump is a freestanding unit with flexible coupling drive, advanced lubrication, and proven reliability for demanding vacuum processes.
Key Features and Benefits
- Two-stage rotary vane design for deeper ultimate vacuum and better vapor tolerance
- High pumping speed of 12.1 CFM (20.4 m³/h) at 60 Hz
- Quiet operation at 57 dB(A)
- Versatile 3-phase motor: 200-230/380-415V 50 Hz or 200-230/460V 60 Hz
- Excellent water vapor handling with adjustable gas ballast
- Pressurized oil lubrication system for long service life and reliability
- Thermal overload protection
- NW25 inlet flange for easy system integration
- Compact footprint suitable for lab and industrial setups

Why Choose the Edwards E2M18 3-Phase? The three-phase motor variant offers greater efficiency and reliability for continuous or high-duty-cycle applications compared to single-phase models. The two-stage design provides significantly better ultimate pressure than single-stage pumps, while maintaining the EM series’ reputation for quiet, dependable performance and easy maintenance.
Applications
- Laboratory vacuum systems
- Analytical instruments and mass spectrometry
- Vacuum drying and degassing
- Refrigeration and air conditioning service
- Light industrial processes and vacuum coating
- General roughing and backing pump duties
What's Included
- Edwards E2M18 Rotary Vane Vacuum Pump (A36310940)
- Ultragrade 19 vacuum pump oil (initial charge)
- NW25 centering ring and O-ring
- Spare seals for oil drain and filler plugs
Note: Power cord / wiring is not included (hard-wired in the electrical box). This is the standard hydrocarbon oil version. For corrosive or aggressive vapor applications, consider the PFPE-prepared E2M18FX variant.
The Edwards E2M18 two-stage rotary vane vacuum pump (3-phase) is a trusted industry-standard solution delivering consistent high performance, quiet operation, and long-term reliability.
