The Varian Turbo-V 301 Navigator is a highly efficient, mid-capacity turbomolecular pump engineered for clean, high-performance high and ultra-high vacuum (UHV) applications. It features Varian's proprietary MacroTorr dynamic staging—incorporating 8 bladed turbine stages followed by 3 specialized molecular drag discs machined from a single block of high-strength aluminum alloy. This unique staging design delivers industry-leading compression ratios for light gases and a high continuous foreline backing pressure tolerance up to 8 mbar.

This exact part number (9698918) is configured with a DN 100 ISO-K high-vacuum inlet flange and a standard manual thumbscrew vent valve. Utilizing permanently lubricated, high-precision ceramic ball bearings installed strictly on the fore-vacuum side, the pump operates entirely free of hydrocarbon contaminating agents, making it ideal for contamination-sensitive analytical and semiconductor environments.

Part Number (MPN): 9698918 / 969-8918
Model Configuration: Turbo-V 301 Navigator (TV 301 NAV)
High Vacuum Inlet Flange: DN 100 ISO-K
Fore-Vacuum / Exhaust Flange: KF16 NW
Drive Electronics Profile: Designed for direct connection to Varian TV 301 Navigator onboard "brick" controllers or remote rack-mount units.

Key Features & Benefits

MacroTorr Drag Technology: Maximizes light gas transport, allowing the system to achieve deep UHV performance while exhausting into compact backing setups.
Maintenance-Free Ceramic Bearings: Features permanently lubricated high-precision ceramic ball bearings that eliminate oil reservoirs, wicks, and the risk of oil back-streaming.
Arbitrary Orientation Mounting: Excellent structural balancing and preloaded internal suspension allow the pump to be operated in any installation angle.
Low Vibration Execution: Rigorous automated factory balancing limits residual vibration displacement to less than 0.01 $\mu$ m at the inlet flange, protecting sensitive analytical detectors.
Thermal Safeguards: Equipped with an integrated thermistor sensor mounted adjacent to the upper bearing to actively protect against system overheating.
