Pfeiffer Vacuum HiPace 1200 Turbo Molecular Pump

Overview

The Pfeiffer Vacuum HiPace 1200 is a high-performance, oil-free turbo molecular pump engineered for ultra-high vacuum (UHV) and extreme high vacuum (XHV) applications in research laboratories, semiconductor process tools, analytical instrumentation (e.g., mass spectrometry, surface analysis), and advanced thin-film deposition systems. Operating on the principle of momentum transfer via high-speed rotating titanium-aluminum alloy blades (37,800 rpm ±2%), the HiPace 1200 achieves exceptional pumping speeds across a broad gas spectrum — including light gases such as hydrogen (1100 L/s) and helium (1300 L/s), as well as heavier species like argon (1200 L/s) and nitrogen (1250 L/s). Its robust rotor dynamics, precision-balanced stages, and optimized blade geometry deliver stable performance under variable inlet pressures and thermal loads. The pump’s ultimate vacuum capability of 5 × 10⁻¹⁰ hPa (equivalent to 5 × 10⁻¹¹ mbar) enables operation in demanding UHV environments where outgassing, virtual leaks, and hydrocarbon contamination must be rigorously controlled.

Key Features

• Oil-free, clean vacuum generation with zero hydrocarbon backstreaming — critical for electron microscopy, XPS, and residual gas analysis
• Integrated drive electronics housed within the pump body, eliminating external controller cabling and reducing footprint
• IP54-rated enclosure for reliable operation in industrial cleanrooms and production-floor environments
• Real-time operational monitoring via embedded sensors (temperature, vibration, bearing status, rotational speed) feeding into TC 1200 controller diagnostics
• Flexible mounting orientation (0–90° vertical or 90–180° inverted) without performance degradation
• Optional corrosion-resistant configuration with nickel-plated housing and specialized coatings for aggressive process chemistries (e.g., Cl₂, NF₃, CF₄)
• Integrated purge gas system with programmable throttle valve and gate valve for controlled venting, bake-out support, and particle mitigation
• Compliance with SEMI S2 safety standards, UL 61010-1, CSA C22.2 No. 61010-1, and TÜV-certified functional safety architecture

Sample Compatibility & Compliance

The HiPace 1200 is compatible with standard vacuum flanges (DN 200 ISO-K, ISO-F, and CF-F variants), enabling seamless integration into existing UHV/XHV chambers and analytical platforms. Its gas-specific compression ratios — exceeding 1 × 10⁸ for Ar and N₂, and maintaining >6 × 10³ for H₂ — ensure effective differential pumping in multi-stage vacuum systems. The pump meets stringent regulatory requirements for laboratory and manufacturing use: full traceability per ISO 9001 quality management, design conformity to IEC 61000-6-2/6-4 EMC standards, and suitability for GLP/GMP environments when paired with TC 1200 controllers supporting FDA 21 CFR Part 11-compliant audit trails and electronic signatures. All units are factory-tested for base pressure, pumping speed uniformity, and rotor stability per DIN 28400 and ASTM F1551 protocols.

Software & Data Management

Control and diagnostics are managed through the TC 1200 controller, offering local LCD interface and remote communication via RS-485 (Modbus RTU protocol). Optional fieldbus integration includes Profibus DP and DeviceNet upon request — facilitating PLC-level supervision in automated tool clusters. The controller logs all operational parameters (startup sequence, coast-down profile, temperature gradients, error flags) with timestamped storage for ≥30 days. Data export is supported via USB or serial connection in CSV format, compatible with LabVIEW, MATLAB, and custom SCADA architectures. Firmware updates are performed securely using signed binaries; version history and calibration metadata are retained in non-volatile memory to satisfy ISO/IEC 17025 documentation requirements.

Applications

• Ultra-high vacuum chambers for scanning electron microscopy (SEM), transmission electron microscopy (TEM), and focused ion beam (FIB) systems
• Residual gas analyzers (RGA) and quadrupole mass spectrometers requiring stable, low-noise vacuum baselines
• Sputtering, evaporation, and atomic layer deposition (ALD) tools where process repeatability depends on consistent gas removal kinetics
• Surface science instruments including Auger electron spectroscopy (AES), low-energy electron diffraction (LEED), and secondary ion mass spectrometry (SIMS)
• Particle accelerator beamline vacuum sections and synchrotron radiation facilities
• Space simulation chambers and cryogenic vacuum test stands

FAQ

What is the recommended backing pump pairing for the HiPace 1200?
A dry scroll pump (e.g., Pfeiffer Vacuum DuoLine series) or diaphragm pump rated for ≥10 m³/h at 1 hPa is required to maintain the foreline pressure below 10 hPa during continuous operation.
Can the HiPace 1200 operate continuously at full speed under load?
Yes — its thermally optimized rotor assembly and dual ceramic bearing system permit uninterrupted operation at nominal speed (37,800 rpm) with inlet pressures up to 1 × 10⁻² hPa for inert gases, provided adequate cooling and backing pressure conditions are maintained.
Is firmware update capability available in the field?
Yes — firmware upgrades are delivered via USB stick or serial interface using Pfeiffer’s certified update utility; all changes are logged with digital signature verification.
Does the pump support analog setpoint control?
No — speed regulation is digital-only via Modbus commands or front-panel inputs; analog voltage/current inputs are not implemented.
What maintenance intervals are specified for routine service?
Under normal operating conditions, the HiPace 1200 requires no scheduled maintenance for 20,000 hours; annual visual inspection of flange seals and electrical connectors is advised per Pfeiffer Vacuum Service Bulletin SB-HiPace-2023-01.
