Property damage from intake of solid particles
During commissioning, there is a risk of damage to the suction chamber from dirt from the system or
the pipes.
► Use a suitable protective strainer ("start-up strainer") in the intake flange.
► Ensure that this strainer is only removed when the risk of solid particles entering the vacuum
Required tools
● Ring spanner, WAF 13 with flange DN 100 ISO-F
● Ring spanner, WAF 24 with flange DN 100 PN16
Connecting the vacuum side
1. Degrease the connection flange.
2. Clear welded lines of any scaling, loose particles etc. prior to installation.
3. Route the piping between the vacuum pump and vacuum chamber so that is remains as short as
4. Select a larger nominal diameter for pipe lengths > 5 m.
5. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
6. Always use all prescribed bolts for fastening the flanges and consider the prescribed pressure
5.5 Connecting the fore-vacuum side
Risk of crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
► Keep limbs out of the reach of the roots pump.
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Risk of damage from gas backflow into the roots pump
Due to the backflow of process gas, the electronic equipment is susceptible to irreversible damage
caused by regenerative energy produced with rotation of the piston.
► Equip the vacuum pump with a facility that prevents the backflow of gases.
► Use, e.g. a shut-off facility on the fore-vacuum side and block the line directly after switching off
► As an alternative, use a backing pump with integrated vacuum safety valve.
