Sanotac VF1005A High-Pressure PTFE-Lined Constant Flow Pump for High-Viscosity Fluids (0–300 cP, 100 mL/min, 5 MPa)

Overview

The Sanotac VF1005A is an engineered high-pressure constant flow pump designed for precise, pulse-free delivery of highly viscous and chemically aggressive fluids under sustained pressure up to 5 MPa. Built upon Couette-type dual-plunger hydraulics with floating plunger compensation and cam-profile flow smoothing, the VF1005A delivers stable volumetric displacement across a viscosity range of 0–300 cP—enabling reliable operation with molten polymers, catalyst slurries, supercritical CO₂ solutions, and corrosive process streams common in catalytic cracking, microreactor synthesis, and continuous-flow hydrogenation. Its all-fluoropolymer-wetted path—including PCTFE-lined stainless steel pump heads, PTFE tubing, sapphire check valves, and Hastelloy fluidic components—ensures long-term compatibility with strong acids, halogenated solvents, and oxidizing reagents while maintaining structural integrity at elevated backpressures.

Key Features

• Dual parallel plunger architecture with real-time electronic pulsation suppression and cam-curve compensation, achieving pressure ripple ≤0.05 MPa and flow repeatability ≤0.1% RSD.
• User-configurable pressure safety limits (upper/lower bounds) with automatic shutdown and alarm logging compliant with IEC 61508 functional safety principles.
• Multi-mode flow control: constant-rate delivery or programmable gradient profiles (up to 32-step ramps), supporting reaction kinetics studies and staged reagent introduction.
• Integrated volumetric (mL/min) and gravimetric (g/min) delivery modes, enabling closed-loop mass-based dosing when interfaced with loss-in-weight (LIW) feed systems via analog 4–20 mA or 0–5 V inputs.
• Onboard flow calibration across nine discrete points (0.01–100.00 mL/min), with user-editable correction factors stored in non-volatile memory to accommodate system-specific compressibility and thermal expansion effects.
• Comprehensive digital communication suite: RS-232 and USB as standard; RS-485/RS-422 optional; full support for Modbus RTU and ASCII protocols for PLC integration and SCADA-level supervision.
• Real-time dual-channel graphical display of pressure and flow rate trends, with timestamped data export to .CSV-compatible Excel format for audit-ready recordkeeping.
• Automated plunger rod cleaning cycle—activated before/after runs—to minimize residue buildup and extend service intervals in abrasive or precipitating media.

Sample Compatibility & Compliance

The VF1005A accommodates Newtonian and mildly shear-thinning fluids up to 300 cP without flow deviation, validated per ISO 5725-2 for precision and trueness under variable inlet conditions. All wetted surfaces meet USP Class VI biocompatibility requirements and ASTM D471 resistance standards for fluoropolymer elastomers. The pump complies with CE electromagnetic compatibility (EMC) Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. When operated within configured pressure and temperature envelopes (ambient to 60°C), it supports GLP-compliant workflows requiring traceable calibration, parameter locking, and electronic audit trails—fully compatible with FDA 21 CFR Part 11–enabled software environments when paired with validated SanoFlu control modules.

Software & Data Management

The SanoFlu Fluid Control Management System provides native Windows-based configuration, real-time monitoring, and automated data capture. It supports method storage (including port settings, protection thresholds, and gradient sequences), encrypted parameter backup, and time-synchronized multi-pump coordination (1:32 master-slave topology). All operational logs—including start/stop timestamps, pressure excursions, calibration events, and communication errors—are recorded with SHA-256 hash integrity verification. Exported datasets include metadata headers compliant with ASTM E1469 for analytical instrument data interchange, facilitating direct ingestion into LIMS or ELN platforms.

Applications

• Catalytic evaluation reactors requiring metered injection of viscous metal-organic precursors or supported catalyst slurries.
• Continuous-flow microreactors processing thermally sensitive intermediates under backpressurized conditions.
• Supercritical fluid processing (e.g., scCO₂ extraction, impregnation, and particle formation) demanding stable mass flow despite density fluctuations.
• High-pressure polymerization systems where monomer feed consistency directly impacts molecular weight distribution.
• Electrochemical flow cells and fuel cell test stations requiring inert, pulseless electrolyte circulation.
• Lab-scale extrusion and foaming lines needing synchronized melt delivery at 5 MPa with <0.1% volumetric drift over 8-hour shifts.

FAQ

What viscosity range is validated for continuous operation?
The VF1005A is factory-validated for stable performance from 0 to 300 cP using Newtonian reference oils (ISO VG 10–100) at 25°C; operation beyond 300 cP is possible but requires derating of maximum pressure and flow rate per Sanotac Engineering Bulletin FL-VP-07.
Can the pump interface with third-party balance systems for loss-in-weight feeding?
Yes—via configurable 4–20 mA or 0–5 V analog input, the VF1005A accepts real-time mass depletion signals to dynamically adjust flow output, forming a closed-loop gravimetric dosing system (hardware customization required per balance model and enclosure class).
Is firmware update capability supported remotely?
Firmware updates are performed locally via USB using signed .bin files distributed through Sanotac’s secure customer portal; remote OTA updates are not implemented to maintain IEC 62443-3-3 security compliance.
Does the pump meet explosion-proof requirements for hazardous area installation?
The base VF1005A is rated for Class I, Division 2 (non-incendive) environments; ATEX/IECEx-certified variants (e.g., VF1005A-EX) are available with intrinsically safe barriers and purged enclosures upon request.
How is flow accuracy verified during routine maintenance?
Accuracy verification follows ASTM D3427: gravimetric collection over ≥5 minutes at three flow points (10%, 50%, and 100% of max), comparing measured mass against theoretical volume corrected for fluid density and temperature—certified calibration certificates are issued per ISO/IEC 17025-accredited labs.
