Leybold Trivac D1.6B Dual-Stage Rotary Vane Vacuum Pump

The Leybold Trivac D1.6B (Part Number: 11227) is a compact, ultra-reliable dual-stage oil-sealed rotary vane vacuum pump engineered for fine vacuum applications. Known for its low noise level, minimal vibration, and thermal stability, the D1.6B delivers stable ultimate total pressure down to 1×10−3 Torr. Its small footprint makes it an ideal choice as a backing pump for high-vacuum systems or for standalone benchtop analytical and research equipment.

Key Features

• Compact Dual-Stage Design: Provides deep ultimate vacuum levels with a space-saving physical layout.

• Low Noise & Low Vibration: Dynamically balanced rotor and internal dampening ensure whisper-quiet operation in laboratory settings.

• Integrated Gas Ballast Valve: Allows handling of condensable vapors to protect pump oil from contamination during wet processes.

• Forced Lubrication System: Internal oil pump provides continuous lubrication to sliding bearings even at high inlet pressures.

• Anti-Suckback Protection: Built-in isolation valve protects the vacuum chamber from oil backstreaming during sudden power loss.

Technical Specifications

Common Applications

• Analytical Instrumentation: Mass spectrometry, gas chromatography (GC-MS), and vacuum centrifuges.

• High Vacuum Backing: Primary foreline pump for small turbomolecular or diffusion pumps.

• Laboratory & R&D: Vacuum desiccators, freeze dryers, glove boxes, and benchtop vacuum ovens.

• Industrial Processing: Small-scale leak detection systems and tube evacuation.
