F-250/1500 Series Turbomolecular Pump
Product Introduction
The F-250/1500 Series Turbomolecular Pump is a high-performance water-cooled vacuum pump designed to generate high and ultra-high vacuum for demanding industrial and scientific applications. The series is widely used in surface analysis, accelerator technology, plasma processing, vacuum electronics manufacturing, semiconductor fabrication, and advanced vacuum engineering.
The product family includes three models to meet different application requirements:
• F250/1500 – Standard Water-Cooled Turbomolecular Pump
• F250/1500T – Ceramic Bearing Water-Cooled Turbomolecular Pump
• F250/1500N – Corrosion-Resistant Ceramic Bearing Water-Cooled Turbomolecular Pump
With precision dynamic rotor balancing, reliable three-phase motor technology, and optimized bearing systems, the F-250/1500 Series delivers stable operation, low vibration, high pumping performance, and long service life for modern vacuum systems.

Features
Common Features
•  High-performance water-cooled turbomolecular pump.
•  Precision dynamically balanced rotor for smooth, low-vibration operation.
•  High pumping efficiency for high and ultra-high vacuum applications.
•  Reliable squirrel-cage three-phase motor.
•  Suitable for continuous industrial operation.
•  Widely compatible with modern vacuum systems.
F250/1500 – Standard Model
•  Imported precision metal ball bearings.
•  Water-cooled structure for stable thermal management.
•  Oil-drop bearing lubrication.
•  Reliable performance with economical operating cost.
•  Vertical installation design.
F250/1500T – Ceramic Bearing Model
•  Imported precision ceramic ball bearings.
•  Lower bearing mass reduces centrifugal force during high-speed rotation.
•  Reduced friction and heat generation.
•  Lower wear and significantly extended service life.
•  Typical bearing life is more than twice that of conventional metal bearings.
F250/1500N – Corrosion-Resistant Model
•  Corrosion-resistant ceramic bearings.
•  Special chemically stable anti-corrosion lubricant.
•  Protective nitrogen (N₂) purge system.
•  Designed for corrosive process environments.
•  Excellent choice for plasma processing, ion etching, and semiconductor manufacturing.

Working Principle
The F-250/1500 Series Turbomolecular Pump operates by using multiple stages of high-speed rotating turbine blades together with stationary stator blades. Gas molecules entering the pump are accelerated in the pumping direction through repeated momentum transfer, allowing efficient removal of gases from the vacuum chamber.
A backing pump maintains the foreline pressure while the turbomolecular pump generates high and ultra-high vacuum. Precision-balanced rotors and high-speed bearings ensure smooth, stable operation with minimal vibration. Water cooling effectively dissipates heat during continuous operation, ensuring excellent reliability and long-term performance.
