How to choose an Oil Lubricated Rotary Vane Pump?

​Rotary Vane Pumps - EU / PVL - Single-stage lubricated pumps

The pumps series EU 45, EU 65 and EU 105 are single-stage pumps of the rotary vane type, lubricated with oil re-circulation.

The flanged electric motor is coupled by means of an elastic coupling. Cooling is ensured by a powerful centrifugal fan. An integrated check valve prevents the oil from rising and the air from returning to the chamber to be emptied during the stop phase. A system for separating the oil mist from the exhaust air is inserted in the tank; the abated oil is automatically recovered by the pump. Gas ballast prevents condensation inside the pump when small amounts of steam are sucked in.

The following EU/PVL series pumps  are suitable for the evacuation of closed systems or to operate at a constant vacuum:​

- EU 45, EU 65 and EU 105

- EU 47/67 (including EU 47HWT & EU67HWT pumps,  the Gas ballast always inserted allows a high capacity to dispose of


- EU 160, EU 205 and EU 300

- EU 650 and EU 1000

- PVL 401 and PVL 541 

- EU 107 H, EU 300 H and EU 650 H (The oil-lubricated vacuum pumps of the EU H series allow for greater capacity and higher vacuum levels).

- EU 160, EU205, EU300 and EU 650 HWT (With high vapour disposal capacity).


The following accessories are available which are useful for installation and for checking the pump operating parameters:

  • External suction filter

  • Vacuum gauges / vacuum switches

  • Manometers / pressure switches

  • Thermostat

  • Minimum oil level switch


Single-stage vacuum pumps offer high performance and quality levels. Their main characteristics are the high pumping speed in an absolute vacuum range between 850 and 0.5 mbar, low noise level, absence of pollution, air cooling, robust construction and easy maintenance. They are used for the suction of air even in the presence of water vapour and for continuous industrial use.

    EU OX Lubricated Single Stage Pumps for Oxygen Treatment

    These pumps are built to be used in plants where oxygen is used, for example during food packaging.

    The use of materials, specially designed to be compatible with the gas being aspirated and the use of synthetic oils, allow the pump to be able to aspirate very high percentages of oxygen, guaranteeing high levels of performance and safety during the process.


    Special Lubricated Single Stage Pumps: W Series

    The W series pumps (cool with flowing water) are single-stage rotary vane pumps, lubricated with recirculating oil. The flanged electric motor is coupled by means of an elastic coupling.


    EU EX – ATEX Lubricated single stage pumps 

    We supply a range of Vacuum pumps approved according to Directive 2014/34/EU and certified for internal/external ATEX zone 1 with temperature class T3 (200°C) to meet the frequent requests for pumps for operation in potentially explosives.
