Overview
The Pfeiffer Vacuum HiPace 400 is a high-performance, oil-free turbo molecular pump engineered for demanding ultra-high vacuum (UHV) and high-vacuum applications in research laboratories, semiconductor fabrication, analytical instrumentation, and industrial process environments. Operating on the principle of momentum transfer—where rapidly rotating titanium-alloy blades impart directional kinetic energy to gas molecules—the HiPace 400 achieves exceptional pumping speeds and compression ratios across light and heavy gases. Its compact, modular architecture integrates the drive electronics directly into the pump housing, eliminating external controllers in standard configurations and reducing electromagnetic interference, cable clutter, and footprint. Designed and manufactured in Germany to stringent DIN/ISO quality standards, the HiPace 400 delivers reproducible base pressures below 1 × 10⁻⁷ hPa (N₂ equivalent) and maintains stable operation under fluctuating inlet conditions typical of sputtering, MBE, CVD, and surface analysis systems.
Key Features
- Integrated digital drive electronics with real-time monitoring of rotor speed, bearing temperature, vibration, and power consumption
- Robust ceramic hybrid bearings with active temperature compensation for extended service life and high reliability in continuous-duty cycles
- IP54-rated enclosure ensuring resistance to dust ingress and limited water splashing—suitable for cleanroom-adjacent and industrial floor environments
- Configurable cooling options: air-cooled (TC 400) for space-constrained labs; water-cooled (TCP 350) for high-duty-cycle or heat-sensitive installations
- Multiple flange interface options: DN 100 ISO-K, CF-F, and ISO-F, enabling seamless integration into existing UHV manifolds and beamline components
- Compliance with Semiconductor Equipment Standards (SEMI S2-0513) for safety and emissions, as well as UL/cUL and CSA certification for North American electrical safety requirements
- Optional Profibus communication interface for integration into automated vacuum control systems compliant with SEMI E10/E15 standards
Sample Compatibility & Compliance
The HiPace 400 is compatible with inert, reactive, and corrosive process gases—including N₂, He, H₂, Ar, O₂, and common precursors used in thin-film deposition and plasma processing—thanks to its all-metal, non-lubricated construction and chemically resistant rotor/stator materials. It meets the mechanical and operational prerequisites for ISO 20483 (vacuum pumps — performance testing), ISO 21360-1 (vacuum technology — calibration of vacuum gauges), and supports GLP/GMP-aligned validation protocols when paired with certified vacuum measurement systems. For regulated environments—including FDA-regulated analytical labs and semiconductor fabs—the pump’s deterministic startup behavior, audit-ready operational logs (via optional TCP/IP or Profibus), and compatibility with 21 CFR Part 11-compliant SCADA platforms facilitate compliance documentation.
Software & Data Management
Pfeiffer Vacuum’s proprietary Vacuum Controller Software (VCS) enables remote commissioning, parameter tuning, and diagnostic logging via Ethernet or RS-485. The HiPace 400 supports Modbus TCP and Profibus DP protocols for interoperability with PLC-based vacuum system supervisors. All operational events—including overtemperature alerts, overspeed shutdowns, and bearing health diagnostics—are timestamped and exportable in CSV or XML format. Firmware updates are delivered via secure HTTPS, and configuration backups can be version-controlled to support traceable maintenance records required under ISO 9001 and IEC 62304 (for medical device vacuum subsystems).
Applications
- Ultra-high vacuum systems for molecular beam epitaxy (MBE), atomic layer deposition (ALD), and pulsed laser deposition (PLD)
- Residual gas analysis (RGA) and quadrupole mass spectrometry (QMS) where low outgassing and minimal hydrocarbon contamination are critical
- Surface science instrumentation including XPS, AES, and LEED systems requiring stable base pressure and rapid pump-down
- Semiconductor manufacturing tools: PVD/CVD chambers, load-lock systems, and beamline transfer stations
- Nuclear physics experiments and particle accelerator beamlines requiring high pumping speed for hydrogen isotopes and helium
- Cryogenic vacuum systems where thermal management and vibration isolation are essential—often deployed alongside cryopumps or cold traps
FAQ
What is the recommended backing pump pairing for the HiPace 400?
A dry scroll pump (e.g., Pfeiffer Vacuum DuoLine series) or diaphragm pump rated for ≥10 mbar ultimate pressure and ≥10 m³/h displacement is recommended to ensure stable forepressure during startup and continuous operation.
Can the HiPace 400 operate continuously at full speed?
Yes—the pump is rated for continuous duty at nominal rotational speed (up to 90,000 rpm), provided ambient temperature remains within 15–35 °C and cooling capacity meets specifications (airflow ≥ 200 m³/h or coolant flow ≥ 1.5 L/min at ΔT = 5 K).
Is the HiPace 400 suitable for oxygen service?
Yes—its metal-only construction, absence of organic lubricants or seals, and passivated surfaces meet ASTM G93 cleaning requirements for high-purity oxygen systems when installed with appropriate upstream filtration and leak-tight metallurgical joints.
How is pump health monitored during operation?
Real-time parameters—including rotor acceleration profile, phase current harmonics, bearing temperature gradients, and vibration spectral analysis—are continuously evaluated by the embedded microcontroller; deviations trigger configurable alarms or safe shutdown per IEC 61508 SIL1 requirements.
Does the HiPace 400 require periodic oil changes or consumable replacement?
No—it is a fully dry, oil-free turbomolecular pump; maintenance intervals are defined solely by bearing lifetime (typically > 20,000 hours under nominal load) and are verified via predictive diagnostics—not scheduled fluid replacement.
