Sanotac SF2005E FFKM/PTFE/Ceramic High-Pressure Metering Pump for Electronic Chemicals

Overview

The Sanotac SF2005E is a high-precision, high-pressure metering pump engineered specifically for ultra-pure and highly corrosive fluid handling in semiconductor manufacturing, advanced packaging, wet etching, cleaning, and precision chemical synthesis applications. Unlike conventional stainless-steel or polymer-lined pumps, the SF2005E features a fully metal-free fluid path constructed exclusively from perfluoroelastomer (FFKM), polytetrafluoroethylene (PTFE), and high-purity technical ceramic—materials certified to meet SEMI F57 and ASTM D471 compatibility standards for aggressive electronic-grade chemicals including HF, HNO₃, TMAH, SC1/SC2 solutions, and photoresist developers. Its dual-piston parallel architecture with floating plunger design ensures stable volumetric displacement under variable backpressure up to 5 MPa (725 psi), enabling reliable long-distance delivery into pressurized reactors or inline filtration systems without flow deviation or seal degradation.

Key Features

• Metal-free wetted path: FFKM seals, PTFE pump head liner, and alumina/zirconia ceramic plungers eliminate metallic ion leaching—critical for sub-28 nm node fabrication where ppq-level metal contamination must be avoided.
• High-resolution flow control: Adjustable in 0.01 mL/min increments across 0.01–200.00 mL/min range; calibrated at 9 user-selectable points (0.01, 0.1, 1, 10, …, 100 mL/min) for traceable accuracy per ISO 5167 and USP analytical instrument qualification guidelines.
• Low-pressure pulsation design: Combines cam-profile compensation with real-time electronic pulse suppression to maintain ≤0.05 MPa pressure ripple—reducing vibration-induced particle generation and ensuring laminar flow in microfluidic manifolds.
• Dual-mode delivery: Supports both volumetric (mL/min) and gravimetric (g/min) operation via optional integration with METTLER TOLEDO or Sartorius analytical balances, enabling closed-loop mass-based dosing compliant with FDA 21 CFR Part 11 audit trails.
• Configurable safety logic: Programmable pressure upper/lower limits with automatic shutdown and event logging; all setpoints stored with timestamped history in non-volatile memory.
• Multi-protocol industrial connectivity: Standard RS-232 and USB interfaces; optional RS-485/422, Modbus TCP/RTU, Profibus DP, and Profinet IRT for seamless integration into Siemens PCS7, Rockwell Logix, or Yokogawa CENTUM VP DCS environments.

Sample Compatibility & Compliance

The SF2005E is validated for continuous operation with Class 1–3 electronic chemicals per SEMI C1–C10 specifications, including anhydrous solvents (e.g., PGMEA), oxidizers (e.g., ozone water), and strong acids/bases. All wetted materials comply with USP Class VI biocompatibility testing and RoHS 2015/863/EU restrictions. The pump meets CE Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU requirements. For GMP-regulated environments, firmware supports ALCOA+ data integrity principles—including electronic signatures, role-based access control, and immutable audit logs exportable as CSV or Excel files with SHA-256 hash verification.

Software & Data Management

The bundled SanoFlu Fluid Control Management System provides full local and remote supervision via Windows-based GUI or web browser interface (HTTP/HTTPS). Real-time dual-channel plotting displays synchronized pressure vs. time and flow rate vs. time curves with configurable sampling intervals (100 ms–5 s). All operational parameters—including gradient profiles, calibration coefficients, and communication settings—are saved as encrypted .cfg files with version stamping. Data export functions generate ISO/IEC 17025-compliant reports containing raw timestamps, measurement uncertainty estimates (k=2), and operator ID metadata. Optional OPC UA server module enables direct historian integration with Emerson DeltaV or Honeywell Experion PKS.

Applications

• Semiconductor front-end: Precise delivery of etchants and strippers into single-wafer cleaning tools (e.g., Tokyo Electron Telius, Lam Research Solstice).
• Advanced packaging: Controlled dispensing of underfill epoxies and die-attach adhesives requiring pulse-free flow at elevated viscosity (up to 10,000 cP).
• Research-scale flow chemistry: Integration into Corning AFR or Vapourtec R-Series reactors for stoichiometric reagent addition under inert atmosphere.
• Photovoltaic manufacturing: Metering of dopant precursors (e.g., POCl₃, BBr₃) in diffusion furnaces with trace-level repeatability.
• Quality control labs: Primary standard for calibrating inline conductivity or UV-Vis sensors in ultrapure water distribution loops (UPW Class E, ASTM D5127).

FAQ

What certifications does the SF2005E hold for use in cleanroom environments?
The pump complies with ISO 14644-1 Class 5 (Fed Std 209E Class 100) particulate emission limits when operated with HEPA-filtered purge gas; full certification documentation includes third-party test reports from SGS Shanghai.
Can the SF2005E be integrated into a GLP-compliant workflow?
Yes—firmware v3.2+ supports 21 CFR Part 11-compliant electronic records, including audit trail activation, biometric login options, and digital signature capture for calibration and maintenance entries.
Is remote firmware update supported over Ethernet?
Firmware upgrades are performed via secure HTTPS upload through the embedded web server; updates require dual-operator approval and generate SHA-256 checksum-verified log entries.
Does the pump support dynamic gradient programming during runtime?
Yes—the SanoFlu software allows real-time modification of ramp rates, hold times, and target flow values without interrupting ongoing operation, with change history logged to persistent memory.
How is leak integrity verified during factory acceptance testing?
Each unit undergoes helium mass spectrometry leak testing (≤1×10⁻⁹ mbar·L/s) at 1.5× maximum rated pressure, with results traceable to NIST SRM 2133 helium permeation standards.
