Pfeiffer TPH 190 Turbomolecular Vacuum Pump

The Pfeiffer TPH 190 is a classic, high-performance hybrid-bearing turbomolecular vacuum pump engineered to deliver reliable high and ultra-high vacuum (UHV) environments. Combining industrial-grade durability with clean vacuum performance, the TPH 190 features a proven dual-bearing design: a wear-free permanent magnetic bearing on the high-vacuum side and a heavy-duty, oil-lubricated ceramic ball bearing on the forevacuum/backing side.

Equipped with a DN 100 ISO-K inlet flange, this workhorse pump is ideal for robust laboratory, R&D, and industrial applications requiring a clean, low-vibration hydrocarbon-free environment, such as mass spectrometry, surface physics, and thin-film deposition.

Key Features & Benefits

• Proven Hybrid Bearing Technology: The permanent magnetic upper bearing runs completely contact-free to eliminate wear and minimize vibration, while the ultra-rugged ceramic lower bearing provides excellent resistance to mechanical shock and pressure surges.

• Hydrocarbon-Free High Vacuum: True ultra-clean performance on the high-vacuum process side, making it highly suitable for sensitive analytical instruments.

• Flexible Cooling Configurations: Supports both conventional forced-air cooling and water-cooling configurations depending on the thermal demands of your cycle or system load.

• Excellent Gas Throughput: Delivers consistent pumping speeds for nitrogen (N2) at approximately 190 l/s, dropping ultimate pressures down to the <1×10−9 mbar range when properly backed and baked.
