Sanotac VF-1005A PTFE-Fluid Path High-Viscosity Precision Metering Pump

Overview

The Sanotac VF-1005A is a high-precision, constant-flow metering pump engineered for reliable delivery of highly viscous and chemically aggressive fluids in demanding laboratory and pilot-scale process environments. Utilizing a dual-piston parallel architecture with floating plunger design and cam-profile flow compensation, the VF-1005A achieves low-pressure pulsation (<0.05 MPa) and exceptional volumetric repeatability (≤0.1%) across its full operating range of 0.01–100.00 mL/min. Its fully fluoropolymer-wetted fluid path—comprising PCTFE pump heads, PTFE tubing, sapphire check valves, ceramic plungers, and Hastelloy components—ensures compatibility with corrosive solvents, strong acids/bases, and high-purity reagents up to 300 cP viscosity. Designed for integration into automated reaction systems, the pump supports closed-loop mass-based dosing via optional gravimetric feedback from load-cell-equipped inlet balances, enabling precise stoichiometric control in catalytic evaluation, microreactor synthesis, supercritical fluid processing, and continuous flow chemistry applications.

Key Features

• Dual-piston parallel drive with floating plunger mechanism for enhanced wear resistance and long-term stability
• PTFE/PCTFE fluid path certified for chemical inertness—validated for use with HF, aqua regia, concentrated HNO₃, and organic peroxides
• Programmable pressure limits (upper/lower bounds) with automatic shutdown and alarm logging
• Real-time dual-curve display: synchronized pressure vs. time and flow rate vs. time on integrated touchscreen interface
• Two operational modes: constant-flow mode and multi-step gradient programming (up to 99 segments)
• User-accessible calibration zone supporting multi-point volumetric correction across the entire flow range
• Electronic pulse suppression algorithm combined with mechanical cam compensation to minimize pressure ripple
• Flexible unit switching between volumetric (mL/min) and mass-based (g/min) delivery, with density input support
• Integrated column cleaning cycle triggered automatically after each run or manually via software command
• Full industrial communications suite: RS232, RS485, USB; native support for Modbus RTU and ASCII protocols

Sample Compatibility & Compliance

The VF-1005A accommodates Newtonian and mildly shear-thinning fluids with viscosities up to 300 cP at 25°C. It is routinely deployed in ASTM D445-compliant viscosity measurement workflows, USP dissolution apparatus auxiliary pumping, and ISO 8504-2-controlled catalyst feeding systems. All wetted materials comply with FDA 21 CFR §177.1550 (PTFE) and §177.2430 (PCTFE), and are extractables-tested per USP . The pump’s firmware architecture supports audit trail generation and electronic signature capability per FDA 21 CFR Part 11 when paired with validated SanoFlu Fluid Control Management Software. Mechanical design conforms to IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions) standards.

Software & Data Management

SanoFlu Fluid Control Management Software provides full remote supervision and configuration via Windows-based desktop application or browser-accessed thin client. It enables real-time monitoring of pressure/flow curves, parameter archiving, and export of time-stamped datasets directly to Excel (.xlsx) format—including raw sensor values, timestamps, and system status flags. All method files (gradient profiles, pressure thresholds, calibration coefficients) are digitally signed and version-controlled. The software logs all user actions—including login/logout, parameter changes, and emergency stops—with immutable timestamps for GLP/GMP traceability. Optional OPC UA server module allows seamless integration into DeltaV, Emerson DeltaV DCS, or Siemens PCS7 environments.

Applications

• Catalytic testing rigs requiring sub-milligram-per-minute dosing accuracy for metal-organic precatalysts and ligand solutions
• Microreactor platforms where pulse-free flow is critical to residence time distribution (RTD) integrity
• Supercritical CO₂ extraction systems needing stable co-solvent injection under 5 MPa backpressure
• Electrochemical flow cells demanding precise electrolyte replenishment without gas bubble entrainment
• Continuous hydrothermal synthesis reactors operating at elevated temperature/pressure with aggressive aqueous media
• Gravimetrically controlled polymerization initiators feed in lab-scale extrusion and foaming trials
• On-line FTIR/NMR reaction monitoring loops requiring synchronized reagent addition and spectral acquisition triggers

FAQ

What is the maximum allowable backpressure for continuous operation?
The VF-1005A is rated for continuous operation at up to 5 MPa (725 psi); intermittent peaks up to 5.5 MPa are permissible with duty cycle limitation.
Can the pump be calibrated in-house without external standards?
Yes—built-in multi-point volumetric calibration allows users to define correction factors across any subset of the 0.01–100.00 mL/min range using gravimetric or timed-collection verification.
Does it support closed-loop control with an external balance?
Yes—the analog input (0–5 V or 4–20 mA) accepts real-time mass loss signals from METTLER TOLEDO, Sartorius, or A&D load cells for dynamic flow adjustment.
Is firmware update possible over USB without disassembly?
Yes—field-upgradable firmware is delivered as signed .bin packages; updates execute via USB connection with rollback capability and checksum validation.
How many pumps can be daisy-chained via RS485?
Up to 32 units may be addressed individually on a single RS485 bus using configurable node IDs and automatic baud-rate detection.
