If the vacuum pump is to be incorporated in machinery assemblies, ensure that ventilation is
adequate.
The vacuum pump will only operate correctly on a horizontal surface capable of supporting
the total mass of the pump and its accessories. Operation on an inclined surface may cause
damage to the pump. In addition, the oil level reading may be incorrect. Make sure to install
the pump so that the nameplate, gas ballast and oil light (s) are visible and accessible.
Above 1000 meters of altitude, vacuum pump performance is impaired (flow rate, final pressure).
 Consult us.
Pump reception
Before installation, check the pump at reception and check the following points:
• Shock or deformation of the protective cover,
•
General condition of the pump,
• Possible leaks,
•
Mounting brackets,
• Compliance.

2.3.

Long-term shutdown

If the vacuum pump is to remain out of service for a fairly long period of time (more than 3 months) or is
not going to be put into service until a later date, empty the pump, fill it with rust-inhibiting oil, run it for 10
minutes then drain off the rust-inhibiting oil. Blank the openings with adhesive tape; close the gas ballast,
store the pump in a dry place. The pump must not be stored in a place that is damp and/or subject to large
temperature variations.
2.4.

Shipping

The machines must be correctly packed in their original packaging before shipping. It is preferable to secure
the package to a European pallet so that it cannot overturn. The pump must be drained before being
shipped.
2.5.

Mounting

The vacuum pumps have silentblocs with tapped holes in the base:
• 3 x M8 for E25.R / E40.R models,
• 4 x M8 for E65.R / E100.R models,
• 4 x M10 for E150.R / E200.R / E300.R / E350.R / E400.R / E500.R / E600.R models.
We recommend that you use these tapped holes to mount the pump on a base frame.
2.6.

Handling

Use the lifting rings provided for that purpose. Never place slings under the pump.

INSTALLATION AND PUTTING INTO SERVICE

3.1. Installation
The suction and discharge ports are protected during transport by caps or stickers. Remove these covers
before commissioning the pump.
Never operate the pump with these guards, as this may destroy the pump.
3.1.1.

Suction

Connect the suction to the process, preferably via a flexible connection, with filters inserted beforehand if
necessary. The flexible connection must withstand the final pressure (0.05 mbar absolute). For the pipe
diameter, at least the connection diameter must be observed. Remember to seal your connections.
To protect the pump, it is recommended to install an upstream filter or separator connected to the suction.
Consult us. This filter must be mounted on the pump in such a way that no solid or liquid particles enter the
pump when replacing the filter element.
The pump is equipped with a non-return check valve to prevent oil from rising upwards if the enclosure
upstream of the suction port remains vacuumised when the pump stops. However, this non-return check
valve is not a safety device. It is recommended to isolate the pump from the vacuum system when it is
switched off. Install an automatic isolation valve that closes when the pump stops, or a non-return check
valve between pump and enclosure.
Never operate the vacuum pump with an open suction connection.
Undersized and/or excessively long suction piping reduces pump performance.
The suction pressure must not exceed the atmospheric pressure.
3.1.2.

Exhaust

Do not reduce or close the exhaust opening. If the discharge is collected, the pipe section
must have a minimum internal diameter equivalent to that of the pump discharge port.
Pipelines must be dimensioned in such a way that the pressure in the piping connected to the
discharge never exceeds 100mbar relative.
If several pumps are connected to the same exhaust piping, the section of the latter must at least be
equivalent to that of the sum of sections of the pumps' discharge ports. The manifold must be designed so
that, if condensation forms in the exhaust piping, it cannot return by flow to one of the pumps. It is
recommended to place a draining system at the lowest point of the discharge piping.
Use a hose that withstands heat and oil vapour to connect to the pipe.
If the exhaust is connected to an extraction system, the relative pressure to the pump discharge must not
drop below -50mbar.
Depending on the application, the gases or vapours released can be harmful to health and/or
the environment. Respect applicable regulations.
