Pfeiffer TPU 240 Turbomolecular Pump

The Pfeiffer Vacuum (formerly Balzers) TPU 240 is a classic, highly dependable turbomolecular pump engineered to deliver a clean, hydrocarbon-free ultra-high vacuum (UHV) environment. This specific variant, designated by Part Number PM P01 330 A (commonly cataloged under the unified PMP01330 series), features a premium DN 100 CF (ConFlat) knife-edge inlet flange designed for critical all-metal-sealed, ultra-clean research applications.

The TPU 240 utilizes a hybrid bearing topology: a completely wear-free permanent magnetic bearing on the clean high-vacuum side, paired with an operating-medium (wick/oil) lubricated ceramic ball bearing on the foreline backing side.This combination delivers excellent rotor stability, resilient protection against sudden atmospheric shock, and easy field serviceability.

• Ultra-Clean UHV Performance: True ConFlat configuration paired with a hybrid magnetic bearing ensures a clean base pressure down into the 10−11 mbar range.

• Hybrid Bearing Topology: Permanent magnetic upper bearings require zero maintenance or lubrication, significantly reducing hydrocarbon back-streaming risks.

• Proven Durability: The Classic-Line monoblock rotor architecture is famous for handling continuous gas loads and demanding cycle environments over decades of reliable tool integration.

• Flexible Operating Environments: Supports multiple cooling methodologies—including convection air or continuous water-assist—to easily manage baking cycles and heavier gas loads.
