TG-F Series · Grease Lubricated Turbo Molecular Pumps
TG-F 50F ~ 2400F
Precision Ceramic Bearing Turbo Molecular Pumps
Engineered with high-performance ceramic ball bearings and advanced grease-lubricated technology, delivering superior mechanical resistance to unexpected air inrushes and ultra-fast startup operations. Factory-sealed grease eliminates the need for field re-lubrication, making it perfect for analytical instrumentation, surface science, and standard semiconductor tools.
Performance Overview
TG-F Precision Bearing Core Advantages
Key Technical Features
-
High-Rigidity Ceramic Bearings & Air Inrush Durability
Equipped with ultra-precise ceramic ball bearings on the shaft assembly. Compared to heavy liquid-lubricated bearings, they provide superior structural rigidity and robust impact protection, securing internal parts from catastrophic failure during accidental vacuum venting or sudden air inrushes.
-
Zero-Refilling Sealed Grease Lubrication System
Utilizing Osaka Vacuum's proprietary enclosed grease technology, the pump operates smoothly without periodic fluid topping or level tracking. This vastly extends preventive maintenance (PM) intervals, minimizing labor overhead and tool downtime.
-
Ultra-Fast Startup Performance & Agile Footprint
Low rotational inertia and prompt thermal equilibrium allow the pump to reach rated operating speed exceptionally fast (compact models accelerate in just 1.5 minutes). Combined with a oil-line-free build, it is optimal for portable pumping skids and analytic instruments.
-
360-Degree Omnidirectional Installation Freedom
Whether installed vertically upright, horizontally, or completely inverted, the TG-F series supports unrestricted orientation. This provides layout flexibility for space-constrained tool enclosures, such as electron microscope columns.
-
Cost-Effective Ultra-High Vacuum Integration
When configured with knife-edge metal-gasket CF (ConFlat) flanges and backed by proper system bake-out, ultimate pressures stable in the UHV range (< 10⁻⁸ Pa) are reliably achieved. Delivers magnetic-levitation tier cleanliness at a highly competitive capital cost.
Vacuum Interface Standards
Compact Mobile Pumping System Integration (ST-Compact)
Osaka Vacuum provides the **ST-Compact Series Turnkey Pumping Skids** utilizing TG-F grease pumps. Fully integrated on a space-saving laptop chassis with dry diaphragm backing pumps or rotary vane pumps, it offers a plug-and-play, portable ultra-high vacuum source for labs.
