Sanotac AF0108A High-Pressure PTFE-Lined Metering Pump

Overview

The Sanotac AF0108A High-Pressure PTFE-Lined Metering Pump is an engineered solution for precise, pulse-free fluid delivery under extreme chemical and pressure conditions. Designed using Couette-flow displacement principles with dual parallel floating plungers, it delivers stable volumetric flow across a wide dynamic range (0.001–10.000 mL/min) at pressures up to 8 MPa (1160 psi). Its chemically inert fluid path—comprising PCTFE-lined stainless steel pump heads, PTFE tubing, sapphire check valves, ceramic plungers, and Hastelloy C-276 wetted components—ensures long-term compatibility with aggressive media including concentrated acids (e.g., HF, HNO₃), alkalis (e.g., NaOH ≥50%), halogenated solvents, supercritical CO₂, and reactive organometallic precursors. The pump operates as a constant-flow positive displacement device, eliminating reliance on backpressure regulation for accuracy—a critical advantage in microreactor feed systems, catalytic evaluation rigs, and continuous flow synthesis platforms where stoichiometric fidelity directly impacts reaction selectivity and catalyst lifetime.

Key Features

• Dual parallel plunger architecture with cam-profiled motion compensation and real-time electronic pulse suppression, achieving pressure ripple ≤0.05 MPa across full operating range
• Multi-point volumetric calibration routine embedded in firmware—supports up to 10 user-defined flow points with non-linear correction coefficients stored per calibration session
• Integrated load-cell interface for gravimetric closed-loop control at reactor inlet; compatible with industrial-grade weighing modules (0.1 g resolution, ±0.05% linearity)
• Patented rear-plunger cleaning mechanism reduces seal wear by >40% versus conventional designs, extending mean time between maintenance (MTBM) to ≥12,000 hours under nominal load
• Configurable output modes: volumetric (mL/min), mass-based (g/min) via density lookup tables, or programmable gradient profiles (linear, step, exponential)
• Hardware-level safety interlocks: over-pressure cut-off (user-settable threshold), dry-run detection via motor current signature analysis, and thermal shutdown at ≥75°C ambient

Sample Compatibility & Compliance

The AF0108A meets material compatibility requirements defined in ASTM D1259 (chemical resistance of fluoropolymers) and ISO 15190:2020 (laboratory safety—requirements for equipment handling hazardous substances). Its wetted materials are certified per FDA 21 CFR §177.1550 (PTFE) and §177.2430 (PCTFE), supporting GMP-compliant use in pharmaceutical process development. The pump’s electrical design complies with IEC 61010-1:2010 (safety requirements for laboratory equipment), including reinforced insulation and double protection against electric shock. For regulated environments, the SanoFlu software supports 21 CFR Part 11-compliant audit trails, electronic signatures, and role-based access control when deployed with validated server infrastructure.

Software & Data Management

The SanoFlu Fluid Control Management System provides native support for method-driven operation, enabling storage and recall of up to 99 independent flow programs—including time-segmented gradients, pause/resume sequences, and conditional triggers based on external sensor inputs (e.g., reactor temperature, pH). Real-time visualization includes synchronized dual-axis plots (flow vs. time, pressure vs. time), with auto-scaled axes and configurable sampling intervals (10 ms–10 s). All operational data—including flow setpoint, actual flow, system pressure, motor torque, and error codes—are timestamped and logged to CSV or SQLite databases. Exported datasets include metadata headers compliant with ISA-88 batch record standards. Remote monitoring and control are supported via optional TLS-secured HTTP API endpoints, enabling integration into MES or cloud-based process analytics platforms.

Applications

• Continuous-flow catalytic hydrogenation and oxidation in fixed-bed or slurry reactors
• Precise co-injection of catalyst precursors (e.g., RuCl₃, Pd(OAc)₂) and substrates in high-throughput screening systems
• Supercritical fluid processing (scCO₂, scCHF₃) for particle engineering and extraction
• Electrolyte dosing in solid-state battery slurry preparation and electrode coating lines
• Controlled reagent addition in exothermic nitration, sulfonation, and Friedel-Crafts acylation reactions
• Gravimetrically referenced feeding in lab-scale polymerization reactors (e.g., polyurethane, silicone elastomer synthesis)

FAQ

What is the maximum allowable viscosity for stable operation at 8 MPa?
The pump maintains rated accuracy up to 500 mPa·s at 25°C when operated below 5 mL/min; above this viscosity, flow rate must be derated per ISO 8503-2 guidelines for positive displacement devices.
Does the AF0108A support fail-safe shutdown during communication loss?
Yes—configurable watchdog timer (1–300 s) triggers immediate flow halt and pressure venting upon loss of master controller heartbeat over RS485 or Modbus TCP.
Can the pump be integrated into a DeltaV DCS environment?
Fully supported via native Modbus TCP or OPC UA (add-on license); pre-certified function blocks available for DeltaV v14.3+ with embedded diagnostics and alarm mapping.
Is NIST-traceable calibration documentation provided with each unit?
Each AF0108A ships with factory calibration certificate (ISO/IEC 17025 accredited lab), including raw test data, uncertainty budgets per ISO 5725, and traceability to NIST SRM 2810.
How is zero-point drift compensated during extended operation?
Automatic zero-offset correction occurs every 24 h or after thermal stabilization (±0.5°C for ≥15 min), using internal reference pressure transducer and plunger position encoder feedback.
