Edwards E2M28FX Two Stage Rotary Vane Vacuum Pump – 19.5 CFM, 380-400V 3-Phase 50Hz / 230/460V 3-Phase 60Hz, PFPE Prepared (A37343940)
The Edwards E2M28FX (part number A37343940) is a high-capacity two-stage oil-sealed rotary vane vacuum pump from the EM series, specially PFPE prepared (FX version) for demanding applications involving corrosive, aggressive, or reactive vapors and gases. This three-phase model features a universal IE3 efficient motor supporting 380-400V 3-ph 50 Hz or 230/460V 3-ph 60 Hz (hard-wired in the electrical box), making it ideal for facilities with three-phase power and continuous-duty operation.
With a strong pumping speed of 19.5 CFM (33.0 m³/h) at 60 Hz and an excellent ultimate vacuum of 1 × 10⁻³ mbar (7.5 × 10⁻⁴ Torr) without gas ballast, the E2M28FX provides faster pump-down and deeper vacuum than smaller models. The FX designation prepares the pump for inert PFPE oils (such as Fomblin® or Krytox®), delivering superior chemical resistance where standard hydrocarbon oils would degrade rapidly.
Key Features and Benefits
- Two-stage rotary vane design for deep ultimate vacuum and high vapor tolerance
-
PFPE prepared (FX version) — excellent compatibility with corrosive and aggressive chemicals
- High pumping speed of 19.5 CFM (33.0 m³/h) at 60 Hz
- Quiet operation at 57 dB(A)
- Efficient IE3 three-phase motor: 380-400V 3-ph 50 Hz or 230/460V 3-ph 60 Hz
- Adjustable gas ballast for improved handling of condensable vapors
- Advanced pressurized oil lubrication system for long service life and reliability
- Thermal overload protection
- NW25 inlet flange for easy system integration
- Rugged freestanding design built for continuous industrial use

Why Choose the Edwards E2M28FX 3-Phase? This 3-phase FX version combines the higher pumping capacity of the E2M28 with full PFPE compatibility and efficient IE3 motor technology. It is the preferred choice for aggressive chemical processes, semiconductor work, or any environment where standard pumps would fail quickly, while offering better efficiency and reliability for continuous-duty applications compared to single-phase models.
Applications
- Chemical and pharmaceutical vacuum processes
- Semiconductor and thin-film coating
- Aggressive vapor handling in laboratories
- Vacuum drying and degassing of reactive materials
- Mass spectrometry and analytical instruments
- Harsh industrial vacuum environments
What's Included
- Edwards E2M28FX Rotary Vane Vacuum Pump (A37343940)
- Initial fill of Ultragrade 19 oil (for testing/break-in)
- NW25 centering ring and O-ring
- Spare seals for oil drain and filler plugs
Important Notes:
-
PFPE oil (Fomblin® or equivalent) is not supplied and must be ordered separately for corrosive service.
- Power cord / wiring is not included (hard-wired in the electrical box).
The Edwards E2M28FX two-stage rotary vane vacuum pump (3-phase, PFPE prepared) delivers higher capacity, strong chemical resistance, quiet operation, and dependable performance for the most challenging vacuum applications.
