MIL’S single-stage oil-lubricated vacuum pump: 68 m³/h nominal flow at 50 Hz and 65 m³/h PNEUROP pumping speed. Standard and HV versions have different end pressures; confirm the required version. View specifications, manufacturer curves and dimensions, or ask Girovac for a quotation.

View quote listThe E65.R provides a useful step into the three-phase EVISA range. At 50 Hz its nominal flow is 68 m³/h, while the measured PNEUROP pumping speed is 65 m³/h. The European version uses 1¼-inch BSP connections; check these and the available supply before replacing an older installation.
EVISA uses oil-lubricated rotary vane technology with an integrated exhaust oil-mist filter. Tell Girovac the working pressure, process gas and operating duty so the pump and supporting equipment can be checked together.
Standard E65.R: ≤ 3 mbar without gas ballast at 50 and 60 Hz. The E65.R HV version is listed at ≤ 0.06 mbar at 50 Hz and ≤ 0.06 mbar at 60 Hz without gas ballast. Do not apply the HV figure to a standard pump.
With gas ballast fully open, the listed end vacuum is ≤ 5 mbar for the standard version and ≤ 3 mbar for HV, at both frequencies. Gas-ballast settings affect vapour handling and the pressure achieved. Specify the gas-ballast arrangement in the quotation.
The manufacturer plots below show evacuation of a 1,000 litre vessel and pumping speed against absolute inlet pressure. Follow the original 50 or 60 Hz line and gas-ballast legend. The low-pressure curves describe HV performance; they do not give a standard E65.R pump an HV pressure rating.
At 50 Hz, the catalogue gives 40 m³/h at 1 mbar for HV duty, compared with 65 m³/h PNEUROP pumping speed. Measurements are specified to PNEUROP 6602 at 20 °C. Actual evacuation time also depends on vessel conditions, pipework, leaks and process gas load. The graphs are vacuum-performance references, not electrical power-consumption curves.
Source note: the table labels the intermediate gas-ballast setting as three rotations, while the curve legend says 1.5 rotations. Both are retained as printed. Ask Girovac to confirm the applicable setting with MIL’S before using that intermediate curve for sizing.
The European version uses three-phase 230/400 v, 50 hz, with a 1.5 kW motor at 1,500 min⁻¹. The listed inlet is 1¼-inch BSP and the outlet is 1¼-inch BSP. Other regional versions can have different motors, voltages, connections and weights.
Check the drawing against the precise motor and pump reference being supplied. Allow access to the oil fill, drain, filters and cooling-air paths; the pump outline is not a service-clearance allowance. For a replacement, send a nameplate photograph and the existing installation dimensions.
The catalogue specifies 3 litres of MV99S 100% synthetic oil for the standard lubrication arrangement. An oxygen-service version needs its own approved lubrication and configuration; do not assume the standard oil specification applies.
The model section lists usual-maintenance kits at 3,000 hours and preventive-maintenance kits at 12,000 hours. Use the operating instructions and actual process conditions to set the service schedule, and quote the serial number when ordering a kit. Inlet filtration, liquid protection and gas-ballast options should be matched to the gas stream and installation.

Nominal flow is 68 m³/h at 50 Hz and 81.6 m³/h at 60 Hz. PNEUROP pumping speed is 65 and 78 m³/h respectively. Use the performance at your working pressure when sizing the pump.
No. This listing covers standard and HV configurations. The standard version is listed at ≤ 3 mbar without gas ballast; the HV version reaches a different stated end vacuum. Specify the variant when enquiring.
The supplied catalogue specifies MV99S 100% synthetic oil and a 3 litre charge for the standard lubrication arrangement. Confirm the exact version and do not apply this specification to oxygen service.
Include the complete model and variant, working pressure, gas or vapour load, vessel volume and required cycle time. Add the electrical supply, connection details and any filters or controls. For an existing pump, include its serial number and a nameplate photo.
For a hazardous-area enquiry, use the separate EVISA ATEX range page. Standard EVISA specifications do not establish ATEX suitability.

Compare the 0–25 mbar absolute capsule gauge for a defined low-pressure dial range with Pirani vacuum transducers for electronic measurement over a wider pressure span. portable meters and data loggers can help record pump-down behaviour. Choose by the actual working pressure and required accuracy, then check the gas and connection.
Yes. Use our vacuum gauge calibration service to specify the instrument, pressure points and certificate requirement. If your process relies on a displayed controller reading, tell us about the complete measuring chain.
