Sanotac SF-1005C High-Pressure Fluorine-Resistant Metering Pump for Hydrofluoric Acid and Anhydrous Hydrogen Fluoride

Overview

The Sanotac SF-1005C is a high-pressure, chemically inert metering pump engineered specifically for the precise, continuous, and safe delivery of highly aggressive fluorinated media—including anhydrous hydrogen fluoride (AHF), hydrofluoric acid (HF), and other strong acids or bases—under demanding laboratory and pilot-scale process conditions. Operating on dual parallel plunger architecture with floating plunger design, the SF-1005C delivers flow rates from 0.01 to 100.00 mL/min at pressures up to 5 MPa (725 psi), with pressure pulsation maintained below 0.05 MPa—a critical specification for stability in catalytic evaluation reactors, microreactor systems, and supercritical fluid applications. Its fluid path is constructed exclusively from fluoropolymer-compatible materials (PCTFE, PTFE) and specialty ceramics, eliminating metallic leaching and ensuring long-term integrity in HF-rich environments where conventional stainless-steel or Hastelloy pumps rapidly degrade.

Key Features

• Chemically resistant pump head: 316 stainless steel housing with precision-machined internal PCTFE liner—no exposed metal in contact with process fluid.
• Dual parallel plunger system with real-time cam-profile compensation and electronic pulse suppression to minimize flow and pressure transients.
• Two operational modes: constant-flow and gradient-flow programs, supporting time-resolved reagent dosing protocols in kinetic studies.
• Configurable mass-based (g/min) or volume-based (mL/min) delivery, with user-accessible calibration across nine discrete flow points (0.01–100 mL/min).
• Integrated pressure and flow curve visualization via embedded display and SanoFlu software—enabling real-time diagnostics and trend analysis.
• Comprehensive safety interlocks: programmable upper/lower pressure limits with automatic shutdown and alarm logging compliant with IEC 61508 functional safety principles.
• Piston rod cleaning system with solvent flush capability to prevent crystallization-induced wear during AHF service.
• Multi-interface connectivity: RS-232 and USB as standard; RS-485/RS-422 optional—supporting both point-to-point and multi-drop Modbus RTU or ASCII protocol configurations.
• Scalable control architecture: supports 1:1 local operation or 1:32 distributed pumping networks via industrial PLC integration.
• Data traceability: all pressure/flow curves and parameter changes are timestamped and exportable to Excel (.xlsx) format, meeting GLP/GMP documentation requirements.

Sample Compatibility & Compliance

The SF-1005C is validated for use with anhydrous hydrogen fluoride (≥99.9%), aqueous hydrofluoric acid (up to 70 wt%), fluorosulfonic acid, chlorosulfonic acid, and other Class 3A/3B corrosive liquids per NFPA 30 and ISO 10218-1 handling guidelines. All wetted components conform to ASTM D471 (fluid resistance) and ASTM F2219 (fluoropolymer compatibility). The pump meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and low-voltage directive (2014/35/EU). Optional configuration supports FDA 21 CFR Part 11-compliant audit trails when used with validated SanoFlu software deployment in regulated pharmaceutical or catalyst development labs.

Software & Data Management

SanoFlu Fluid Control Management System provides full remote supervision, including real-time monitoring of pressure/flow waveforms, parameter versioning, and secure user-role management (admin/operator/auditor). It logs all setpoint changes, alarm events, and calibration actions with digital signatures and immutable timestamps. Exported datasets include metadata (pump ID, operator, date/time, environmental temperature), enabling traceable correlation with reactor output data in LIMS or ELN platforms. The software supports OPC UA server integration for seamless interoperability with DeltaV, Emerson DeltaV DCS, or Siemens PCS7 control systems.

Applications

• Catalytic testing: precise co-feeding of HF and organic substrates into fixed-bed or slurry-phase reactors for alkylation, isomerization, and fluorination kinetics.
• Microchemical synthesis: stable reagent introduction into chip-based or capillary microreactors operating under elevated pressure and temperature.
• Supercritical fluid processing: metered injection of HF or fluorinated solvents into scCO₂ or scNH₃ systems for extraction or impregnation.
• Electrolyte formulation: gravimetrically controlled dispensing into glovebox-integrated battery R&D lines (e.g., LiF formation studies).
• Corrosion testing rigs: continuous exposure of alloy coupons to dynamic HF concentration gradients under controlled pressure profiles.
• Foaming & extrusion: synchronized delivery of fluorinated blowing agents into polymer melt streams for closed-cell foam development.

FAQ

Is the SF-1005C suitable for anhydrous hydrogen fluoride vapor phase service?
No—the SF-1005C is designed exclusively for liquid-phase metering. Vapor-phase HF requires specialized diaphragm or bellows-sealed systems with heated tracing and condensate management.
Can the pump be integrated with a loss-in-weight (LIW) feeder system?
Yes—via analog input (0–5 V or 4–20 mA) and closed-loop PID control logic in SanoFlu software, enabling real-time feedback adjustment based on load cell output.
What maintenance intervals are recommended for AHF service?
Plunger seals require inspection every 200 operational hours; ceramic check valves every 500 hours. A full fluid-path refurbishment kit is available with certified PCTFE/PTFE replacement components.
Does the pump support automated calibration verification per ISO/IEC 17025?
Yes—SanoFlu includes a calibration verification workflow with reference gravimetric measurement prompts, uncertainty propagation reporting, and certificate generation compatible with accredited lab workflows.
Is explosion-proof certification available?
ATEX II 2G Ex db IIB T4 Gb and IECEx certification are available as factory-installed options for Zone 1 hazardous area deployment.
