Edwards E1M18 – single-stage rotary vane vacuum pump
The E1M18 belongs to Edwards' EM series of small oil-sealed rotary vane pumps. It delivers 17 m³/h at 50 Hz and 20.4 m³/h at 60 Hz and reaches an ultimate pressure of 0.03 mbar without gas ballast, 2 mbar with gas ballast. The motor power is 0.75 kW (single-phase) or 0.55 kW (three-phase) at 50 Hz. The sound pressure level is 57 dB(A); with the optional acoustic enclosure it drops to around 50 dB(A). The pump weighs approx. 38 kg and measures 532 × 180 × 271 mm (single-phase) or 474 × 180 × 271 mm (three-phase).Design and equipment
- Gas ballast valve for pumping vapours (water vapour tolerance 50 mbar)
- Suction connection NW25, outlet with 15 mm hose nozzle
- Simple installation without customer wiring on the versions with appliance connector
- Approvals to EN 61010, CSA C22.2, UL 61010; pumping chamber rated to ATEX II 3 G Ex h IIB T4 Gc
- RoHS-compliant
Typical applications
For the EM pumps Edwards names scientific and laboratory applications and use as a backing pump for turbomolecular pumps; the pumps have also proven themselves in industrial applications.Versions of the Edwards E1M18
The E1M18 is available in 5 versions (part numbers A34317984, A34310905, A34310925, A34315904, A34325984). The three-phase and the Japanese 100/200 V versions are hard-wired; the versions with IEC appliance connector need a mains cable ordered separately. FX versions are prepared for PFPE oil; the PFPE oil is ordered separately. The market details (Europe/USA, Asia, Japan) come from the Edwards ordering documents.Advice and service
