Sanotac VF1005A High-Viscosity, High-Pressure Fluoropolymer-Compatible Constant Flow Pump

Overview

The Sanotac VF1005A is a precision-engineered, high-viscosity, high-pressure constant flow pump designed for demanding laboratory and pilot-scale applications requiring accurate, pulse-free delivery of viscous and chemically aggressive fluids. Operating on dual parallel plunger architecture with floating plunger design, the pump leverages Couette-flow hydrodynamic principles to maintain stable volumetric displacement under elevated backpressure—up to 5 MPa (725 psi). Its fluoropolymer-compatible fluid path—featuring PCTFE pump heads, PTFE seals, sapphire check valves, ceramic plungers, and Hastelloy wetted components—ensures long-term chemical resistance against strong acids, halogenated solvents, catalysts, and supercritical fluids. Unlike peristaltic or diaphragm pumps, the VF1005A delivers true positive displacement with minimal shear, making it suitable for shear-sensitive suspensions, slurries, and highly concentrated catalytic feedstocks.

Key Features

• Dual parallel plunger system with floating plunger compensation for consistent stroke volume across pressure and viscosity gradients
• Fluoropolymer-wetted path (PCTFE pump head, PTFE seals, sapphire valves, ceramic plungers, Hastelloy fittings) certified for continuous exposure to corrosive media up to 5 MPa
• Flow range: 0.01–100.00 mL/min with 0.01 mL/min resolution; accuracy ±0.5%, repeatability ≤0.1% (per ISO 5725-2:2019)
• Low-pressure pulsation (≤0.05 MPa) achieved via cam-profile compensation and real-time electronic pulse suppression algorithm
• Configurable flow control modes: constant-flow and gradient-programmed operation (user-defined time/flow profiles)
• Integrated pressure and flow curve visualization in real time, with timestamped data logging to Excel-compatible CSV files
• Onboard user calibration suite supporting up to nine independent flow correction points (0.01, 0.1, 1, 10, 20, 40, 60, 80, 100 mL/min)
• Comprehensive I/O interface: 0–5 V and 4–20 mA analog inputs for closed-loop integration with gravimetric feed systems (e.g., reactor inlet mass loss scales)
• Multi-protocol digital communication: RS-232 and USB (standard), RS-485/422 (optional), supporting both Modbus RTU and ASCII command sets
• Scalable control architecture: supports one-to-many configuration (up to 32 units per master controller) and simultaneous multi-pump gradient synthesis

Sample Compatibility & Compliance

The VF1005A is validated for handling Newtonian and mildly non-Newtonian liquids within 0–300 cP viscosity range—including polymer melts, catalyst slurries, ionic liquid solutions, supercritical CO₂ co-solvents, and viscous organometallic precursors. Its materials of construction comply with ASTM F2136-18 (fluoropolymer compatibility) and meet requirements for GMP-aligned process analytical technology (PAT) environments. The pump’s firmware supports audit-trail-enabled operation when integrated with SanoFlu Fluid Control Management System, enabling compliance with FDA 21 CFR Part 11 for electronic records and signatures. All electrical components conform to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards.

Software & Data Management

The SanoFlu Fluid Control Management System provides full remote supervision and parameter orchestration via Windows-based GUI. It enables synchronized multi-pump gradient programming, real-time pressure/flow overlay visualization, and automated data export with metadata tagging (operator ID, timestamp, method name, instrument serial number). Logged datasets include raw sensor values, calculated flow rates, pressure differentials, and system status flags—all stored in open-format CSV files compatible with MATLAB, Python (pandas), and LIMS platforms. Configuration templates—including port settings, pressure limits, flow programs, and calibration coefficients—are encrypted and version-controlled, supporting reproducible method transfer across instruments and laboratories.

Applications

• Catalytic evaluation reactors: precise metering of viscous catalyst suspensions (e.g., Ni/Mo sulfides in diesel fractions) into fixed-bed or slurry-phase reactors
• Microreactor systems: stable reagent dosing for continuous-flow hydrogenation, oxidation, and cross-coupling reactions under high backpressure
• Supercritical fluid processing: controlled delivery of modifier solvents (e.g., methanol in scCO₂) for extraction and particle formation
• Gravimetric feeding loops: closed-loop control interfaced with precision load cells for mass-loss-based feed rate regulation in batch and semi-batch reactors
• Advanced material synthesis: metering of high-concentration polymer precursor solutions (e.g., polyimide dopes, battery slurry binders) in coating and extrusion R&D
• Energy research: feeding viscous bio-oils, heavy crude fractions, and molten salt mixtures in thermal cracking and electrochemical cell testing rigs

FAQ

What is the maximum allowable viscosity for continuous operation?
The VF1005A is rated for continuous operation with fluids up to 300 cP at ambient temperature and full pressure capacity (5 MPa). For viscosities exceeding 200 cP, pre-heating the fluid path to reduce effective viscosity is recommended to maintain optimal plunger seal life and flow stability.
Can the pump be integrated into an existing PLC-controlled reaction system?
Yes—the VF1005A supports native Modbus RTU over RS-485 and accepts 0–5 V / 4–20 mA analog setpoints, enabling seamless integration with Allen-Bradley, Siemens, and Beckhoff PLCs without middleware.
Is gravimetric closed-loop control supported out-of-the-box?
The pump includes dedicated analog input channels and built-in PID logic for direct integration with third-party mass loss scales; hardware-level customization (e.g., load cell excitation voltage matching) is available upon specification.
How is flow calibration performed in the field?
Calibration is executed via the SanoFlu software using user-defined reference points; each point triggers automatic adjustment of internal displacement coefficients based on gravimetric or volumetric collection measurements.
Does the pump support regulatory-compliant data integrity practices?
When operated with SanoFlu software in audit mode, all parameter changes, start/stop events, and calibration actions are time-stamped, user-logged, and cryptographically signed—fulfilling ALCOA+ principles and 21 CFR Part 11 requirements for electronic records.
