The Leybold TURBOVAC SL 80 is a compact, premium-line mechanical bearing turbomolecular pump engineered to deliver reliable, oil-free high and ultra-high vacuum (UHV) conditions. Designed with precision multi-stage rotor blade geometry and an integrated Holweck molecular drag stage, the SL 80 provides exceptional light-gas compression ratios and a high foreline pressure tolerance of up to 20 mbar.

This specific configuration, Part Number 800002V3002, features a DN 63 CF (4.50" OD) ConFlat high-vacuum inlet flange. This metal-sealed, ultra-clean knife-edge flange allows the pump to be fully baked out, enabling the system to reach deep UHV pressures down into the $10^{-10}$ mbar range. The pump utilizes lifetime grease-lubricated ceramic ball bearings, allowing for vibration-free operation and highly flexible installation configurations.

Part Number (MPN): 800002V3002
Inlet Flange (High Vacuum): DN 63 CF (4.50" OD)
Outlet Flange (Fore-Vacuum): DN 16 ISO-KF
Lubrication System: Dry, lifetime-lubricated ceramic bearings
Required Controller: TURBO.DRIVE TD 400 series

Key Features & Benefits

True UHV Performance: Equipped with an all-metal ConFlat inlet flange, minimizing outgassing and enabling ultimate pressures as low as $2.0 \times 10^{-10}$ mbar ( $1.5 \times 10^{-10}$ Torr).
High Foreline Tolerance: The secondary Holweck drag stage accommodates backing line pressures up to 20 mbar(15 Torr), allowing it to work seamlessly with smaller backing pumps.
Arbitrary Orientation Mounting: Unique mechanical suspension design allows the pump to be operated in any installation angle or orientation without performance penalties.
Split-Cage DC Motor: Windings are separated from the vacuum zone by a vacuum-tight can wall, eliminating electrical feedthrough risks and preventing process contamination.
Purge & Vent Ready: Built-in purge gas facility allows the injection of a clean sealing gas stream to safeguard mechanical internals during sensitive operations.
