Pfeiffer Vacuum HiPace 300–800M & ATH 500 M Full-Magnetic Levitation Turbomolecular Pumps

Overview

The Pfeiffer Vacuum HiPace 300–800M and ATH 500 M series represent the industrial benchmark for high-reliability, oil-free high-vacuum generation in demanding research and production environments. Engineered on the principle of molecular drag and momentum transfer via ultra-high-speed rotating titanium-alloy rotor blades, these full-magnetic levitation turbomolecular pumps operate without mechanical contact between rotating and stationary components. The proprietary 5-axis active magnetic bearing system eliminates conventional ball or foil bearings—removing wear mechanisms, lubrication requirements, and vibration sources inherent in hybrid or passive magnetic designs. This architecture enables continuous operation at rotational speeds up to 90,000 rpm with sub-micron dynamic centering precision, delivering exceptional pumping stability across variable gas loads and thermal transients. Designed for integration into UHV (ultra-high vacuum) and XHV (extreme-high vacuum) systems—including surface science chambers, electron microscopy columns, mass spectrometers, and thin-film deposition tools—the HiPace M and ATH 500 M series maintain ultimate pressures down to 1×10⁻⁸ mbar (N₂) and demonstrate compression ratios exceeding 10¹⁸ for light gases such as hydrogen and helium—critical for hydrogen-rich process environments and residual gas analysis.

Key Features

• Full 5-axis active magnetic levitation: Enables true contactless rotation, eliminating bearing wear, oil contamination, and particulate generation—essential for cleanroom-compatible and semiconductor-grade vacuum applications.
• Integrated digital drive electronics: Compact controller housed within the pump base provides real-time monitoring of rotor position, temperature, speed, vibration spectra, and power consumption—accessible via RS-485, EtherCAT, or optional Ethernet/IP interface.
• Multi-angle mounting capability: Rotor dynamics and magnetic control algorithms are validated for installation in horizontal, vertical, or inverted orientations without performance degradation or recalibration.
• Automatic dynamic balancing compensation: Onboard sensors continuously detect mass asymmetry shifts (e.g., from condensate accumulation or thermal distortion) and adjust magnetic actuator currents in real time to suppress synchronous vibration below 0.5 µm peak-to-peak displacement.
• Low electromagnetic interference (EMI) design: Optimized coil winding geometry and shielded power stages ensure compliance with IEC 61000-6-4 emission limits—enabling co-location with sensitive electron optics and RF instrumentation.
• Energy-efficient operation: Typical power draw ranges from 350 W (HiPace 300M) to 1,100 W (HiPace 800M) at full speed—reducing thermal load on vacuum chambers and facility cooling infrastructure.

Sample Compatibility & Compliance

These pumps are compatible with inert, reactive, and corrosive gas species—including O₂, N₂, Ar, He, H₂, CO, CO₂, and low-concentration process vapors—provided inlet gas composition remains within Pfeiffer’s specified partial pressure limits for titanium rotor materials (e.g., <1×10⁻³ hPa H₂O during pump-down). They are routinely deployed in GLP- and GMP-regulated environments where trace hydrocarbon contamination must be excluded; their oil-free operation meets ASTM E1921 requirements for vacuum cleanliness in materials testing. All HiPace M and ATH 500 M units are manufactured under ISO 9001:2015 quality management systems and bear CE marking per EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Firmware supports audit-trail logging compliant with FDA 21 CFR Part 11 when integrated with validated SCADA platforms.

Software & Data Management

Pfeiffer’s VacuGraph® PC software (v5.0+) provides full remote configuration, real-time diagnostics, and predictive maintenance analytics—including bearing health scoring derived from harmonic vibration amplitude trends over time. Pump data streams (rotor displacement FFT, temperature gradients, power spectral density) are exportable in CSV and HDF5 formats for integration into LabVIEW, Python-based monitoring dashboards, or MES systems. Optional OPC UA server module enables native interoperability with Siemens Desigo, Rockwell FactoryTalk, and Schneider EcoStruxure architectures. Firmware updates are delivered via signed binary packages with SHA-256 verification—ensuring integrity and traceability in regulated facilities.

• Residual gas analyzers (RGAs) and quadrupole mass spectrometers requiring stable ion source pressure
• Atomic layer deposition (ALD) and molecular beam epitaxy (MBE) reactors with stringent hydrocarbon and water vapor specifications
• Space simulation chambers meeting ECSS-E-ST-20-07C outgassing requirements
• Quantum computing dilution refrigerator foreline and mixing chamber pumping stages

FAQ

What is the recommended backing pump pairing for HiPace 300–800M series?
Dry scroll pumps (e.g., Pfeiffer DuoLine series) or diaphragm pumps are preferred for hydrocarbon-free backing; rotary vane pumps may be used only if equipped with cold traps and hydrocarbon filters.
Can HiPace M pumps operate continuously under high gas load conditions?
Yes—integrated thermal management and overload protection algorithms allow sustained operation at ≤30% of nominal pumping speed against inlet pressures up to 10 hPa (N₂), provided backing pressure remains <0.5 hPa.
Is firmware update capability available in standalone mode?
Yes—updates can be performed via USB memory stick without network connectivity, with rollback support and version-signed validation.
What is the typical service interval for magnetic bearing calibration?
No periodic recalibration is required; the system self-calibrates during every startup sequence using factory-trimmed Hall sensor offsets and current-loop gain tables.
Are explosion-proof variants available for solvent-rich environments?
ATEX-certified versions (II 2G Ex db IIB T4 Gb) are available for HiPace 700M and 800M upon request, with intrinsically safe control interfaces and enhanced rotor containment design.
