Leybold TRIVAC D 16 B Dual-Stage Rotary Vane Vacuum Pump – Part # 11266 (3-Phase Motor)
Leybold TRIVAC D 16 B (PN 11266) three-phase version for reliable performance in research and production. 22.7 m³/h speed, low ultimate pressure.
The Leybold TRIVAC D 16 B is a proven, robust double-stage oil-sealed rotary vane vacuum pump designed for reliable performance in laboratory, research, and light industrial applications. With its durable construction and efficient 3-phase motor, this pump delivers consistent medium vacuum while offering excellent water vapor tolerance and long service life.
It provides a nominal pumping speed of 18.9 m³/h (50 Hz) / 22.7 m³/h (60 Hz) and achieves an ultimate pressure of < 2 × 10⁻³ mbar (without gas ballast), making it ideal for a wide range of vacuum processes. The integrated gas ballast helps handle humid or condensable vapors effectively.
Key Features & Benefits:
- Double-stage design for lower ultimate pressures and better performance
- Quiet operation with low vibration — suitable for laboratory environments
- High water vapor tolerance (up to 305 g/h with gas ballast)
- Reliable 0.75 kW (1 HP) three-phase motor for stable, continuous duty
- Robust Leybold engineering with easy maintenance and long service intervals
- KF25 (DN 25 ISO-KF) inlet and outlet connections
- Weight: 28 kg — compact yet heavy-duty build
Typical Applications:
- Laboratory vacuum systems and research & development
- Analytical instruments
- Vacuum drying, degassing, and distillation
- Backing pump for turbomolecular or diffusion pumps
- Refrigeration service, coating, and light industrial processes
Technical Specifications:
- Pumping speed (50/60 Hz): 16.5 / 19.8 m³/h (actual) | Nominal: 18.9 / 22.7 m³/h
- Ultimate total pressure (without gas ballast): < 2 × 10⁻³ mbar
- Motor: 0.75 kW (1 HP), 3-phase (200–230/380–460 V, 50/60 Hz)
- Oil capacity: ~1.0–1.5 L (LEYBONOL LVO 130 recommended)
- Noise level: Approximately 50–54 dB(A)
Backed by Leybold’s reputation for quality and engineering excellence, the TRIVAC D 16 B is a trusted choice when you need dependable, low-maintenance vacuum performance.
