Pfeiffer Vacuum HiScroll 6 Dry Scroll Vacuum Pump

Overview

The Pfeiffer Vacuum HiScroll 6 is a compact, oil-free dry scroll vacuum pump engineered for high-reliability primary vacuum generation in analytical, research, and light industrial environments. Based on proven scroll compression technology, the HiScroll 6 operates without lubricating oil—eliminating hydrocarbon backstreaming, reducing maintenance intervals, and ensuring clean vacuum conditions essential for mass spectrometry sample introduction, vacuum drying, glovebox evacuation, electron microscopy chamber prep, and thin-film deposition support. Its dual-stage scroll mechanism achieves an ultimate pressure of 1.5 × 10⁻² hPa (1.5 × 10⁻³ mbar) without gas ballast, while maintaining stable performance across variable inlet pressures up to 1100 hPa (ambient). Designed and manufactured in Germany under stringent quality control, the HiScroll 6 complies with IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity), and meets RoHS and REACH requirements.

Key Features

• Oil-free dry scroll technology ensures contamination-free vacuum — critical for UHV-adjacent applications and sensitive surface analysis techniques.
• Wide-speed-range brushless DC motor (1,000–3,000 rpm) enables precise pumping speed modulation via analog or digital input (0–10 V or RS-485), supporting adaptive process control.
• Integrated thermal management and low-vibration mechanical design yield acoustic emissions of only 48 dB(A) at 1 m — suitable for shared laboratory spaces and noise-sensitive facilities.
• Compact footprint (320 × 220 × 310 mm) and lightweight construction (19 kg) facilitate benchtop integration, mobile cart mounting, or OEM system embedding.
• IP20-rated enclosure provides protection against solid objects ≥12.5 mm; optional ATEX-certified explosion-proof variant (Ex II 3G Ex h IIC T4 Gc X) is available for Zone 2/22 hazardous areas with ambient temperature limits of +5 °C to +40 °C.
• Standard DN 25 ISO-KF inlet flange ensures rapid, leak-tight connection to common vacuum tubing and components; no special tooling required.

Sample Compatibility & Compliance

The HiScroll 6 is compatible with non-corrosive, non-condensable gases and low-vapor-pressure vapors typical in inert-gas purging, solvent-free vacuum drying, and vacuum degassing of polymers or adhesives. It is not intended for continuous pumping of condensable solvents (e.g., water, acetone, ethanol) without optional gas ballast or external cold trap integration. The pump conforms to ISO 21809-3 for vacuum equipment safety, EN 61000-6-4 for industrial EMC compliance, and carries CE marking per the EU Machinery Directive 2006/42/EC. For regulated environments—including GLP, GMP, or FDA-regulated laboratories—the pump supports audit-ready operation when paired with Pfeiffer’s HiControl software (see Software & Data Management section).

Software & Data Management

The HiScroll 6 supports both standalone operation and intelligent integration via Pfeiffer Vacuum’s HiControl software suite (Windows-based, USB/RS-485 interface). HiControl provides real-time monitoring of rotational speed, motor current, bearing temperature, and runtime hours; enables programmable start/stop sequences, pressure-controlled speed ramping, and event logging with time-stamped entries. All operational data—including error codes, warning thresholds, and firmware version—are exportable as CSV for traceability. When deployed in validated systems, HiControl can be configured to comply with FDA 21 CFR Part 11 requirements through user access levels, electronic signatures, and immutable audit trails—facilitating regulatory submissions and internal QA reviews.

Applications

• Primary vacuum backing for turbomolecular pumps in residual gas analyzers (RGAs) and quadrupole mass spectrometers.
• Evacuation of environmental chambers, desiccators, and inert-atmosphere gloveboxes (N₂, Ar).
• Support vacuum for freeze-dryers, lyophilizers, and vacuum ovens where oil-free conditions prevent product cross-contamination.
• OEM integration into automated material testing systems, semiconductor metrology tools, and plasma etch load-lock modules.
• Routine vacuum maintenance in university teaching labs, R&D centers, and QC laboratories requiring reliable, low-maintenance vacuum sources.

FAQ

Is the HiScroll 6 suitable for pumping water vapor or solvent vapors?
The standard HiScroll 6 is not recommended for continuous condensable vapor duty. For intermittent water vapor exposure, use with gas ballast (if equipped) or install an inline cryo- or adsorption trap. Continuous solvent pumping requires application-specific engineering review.
Does the pump require routine oil changes or filter replacements?
No — as an oil-free dry scroll pump, it has no lubrication system or exhaust filters. Scheduled maintenance is limited to periodic inspection of inlet mesh (if installed), cooling fan cleanliness, and verification of vibration/noise signature.
Can the HiScroll 6 be operated in a vertical orientation?
It is designed and tested exclusively for horizontal operation (inlet facing upward or sideways). Vertical mounting voids warranty and compromises thermal dissipation and scroll alignment.
What communication protocols are supported for remote control?
Standard models support analog 0–10 V speed control and status feedback. Optional RS-485 interface enables Modbus RTU protocol for integration into PLC-based vacuum control systems.
Is calibration or factory certification provided with delivery?
Each unit ships with a Declaration of Conformity and factory test report documenting ultimate pressure, pumping speed, and noise level. NIST-traceable calibration is available as a value-added service upon request.
