The Varian Turbo-V 70D MacroTorr is a highly reliable, compact turbomolecular vacuum pump engineered for clean, high-performance applications across precision laboratories, analytical instrumentation, and advanced research environments. Featuring Varian's proprietary MacroTorr dynamic staging architecture, the pump incorporates high-efficiency molecular drag stages directly onto the rotor assembly. This allows it to achieve industry-leading compression ratios for light gases and a high foreline pressure tolerance, enabling it to exhaust into compact, cost-effective roughing configurations.

This specific configuration, Part Number 9699361, features a standard KF40 high-vacuum inlet flange and an integrated thumbscrew vent valve. Utilizing maintenance-free dry ceramic ball bearings, the V70D guarantees completely oil-free, vibration-isolated operation in any mounting orientation.

Key Features & Benefits

MacroTorr Drag Technology: Staged helix channels handle significantly higher backing pressure profiles without sacrificing critical high-vacuum throughput.
Maintenance-Free Bearings: Advanced ceramic ball bearings are lubricated with high-stability dry synthetic grease, eliminating oil-wick cartridges and the risk of hydrocarbon back-streaming.
Arbitrary Orientation: Lightweight design and specialized internal mechanical preload suspension allow the pump to operate at any angle.
High Pumping Efficiency: Optimized for immediate gas transport, reaching full operational frequency rapidly with minimum power draw.
Integrated Vent Facility: Features a factory-installed manual thumbscrew vent valve for simple system venting routines.
