Overview
The Sanotac JL0012 High-Pressure Liquid Delivery Pump is an engineered constant-flow precision instrument designed specifically for integration into laboratory-scale distillation systems—including batch, continuous, reactive, and extractive distillation setups. It operates on a dual-piston serial pumping principle with floating piston architecture, enabling stable, pulse-minimized fluid delivery under sustained high backpressure up to 42 MPa (6,090 psi). Its core function is to provide accurate, programmable, and reproducible liquid transport of feedstocks, catalysts, solvents, or supercritical fluids in process development environments where flow integrity directly impacts separation efficiency, mass balance accuracy, and thermodynamic data fidelity. Unlike general-purpose peristaltic or diaphragm pumps, the JL0012 employs solvent compressibility compensation and multi-point flow calibration algorithms—ensuring metrological consistency across its full dynamic range (0.001–9.999 mL/min), making it suitable for both analytical-scale column feeding and preparative-scale process simulation.
Key Features
- Dual-piston serial configuration with floating piston design reduces seal wear and extends service life of high-pressure sealing components.
- Microprocessor-based control system supports programmable flow rates with 0.001 mL/min resolution and certified accuracy of ±0.1% and repeatability ≤0.1% RSD.
- Integrated gradient capability enables user-defined combinations of isocratic, linear, and step gradients—facilitating method development for complex multicomponent separations.
- Cam-profile compensation and real-time electronic flow pulsation suppression maintain pressure stability ≤0.1 MPa peak-to-peak under variable load conditions.
- Chemically inert wetted path composed of 316L stainless steel, sapphire check valves, PTFE seals, and ceramic pump heads ensures compatibility with aggressive organic solvents, acids, bases, and supercritical CO₂.
- Open communication protocol (RS232/Ethernet) allows bidirectional control and monitoring via third-party chromatography data systems or custom LabVIEW/Python automation frameworks.
- Front-panel interface with 256×64 backlit LCD supports storage of ten independent user methods, including flow ramping, gradient timing, and pressure limit settings.
Sample Compatibility & Compliance
The JL0012 is validated for use with low-to-medium viscosity liquids (up to 500 cP) across temperature ranges from 5 °C to 45 °C ambient operation. Its material construction complies with ASTM F2136-20 (standard specification for elastomeric seals in pharmaceutical processing) and meets mechanical safety requirements outlined in IEC 61010-1:2010 for laboratory equipment. While not intrinsically rated for hazardous area use, optional PCTFE- or Hastelloy-C276-wetted variants are available for corrosive service in fine chemical synthesis or coal liquefaction research. The pump supports GLP-compliant audit trails when integrated with validated CDS platforms adhering to FDA 21 CFR Part 11 requirements for electronic records and signatures.
Software & Data Management
The pump’s embedded firmware implements a vendor-neutral command set documented in publicly accessible technical annexes, enabling seamless integration with commercial chromatography data systems (e.g., Thermo Chromeleon, Waters Empower, Agilent OpenLab) as well as open-source control environments. All operational parameters—including actual flow rate, delivered volume, system pressure, and error codes—are timestamped and exportable via CSV or XML over standard Ethernet TCP/IP. Internal memory retains run logs for ≥10,000 events with automatic rollover, supporting traceability in QA/QC workflows and regulatory submissions.
Applications
- Feed delivery in pilot-scale fractional distillation columns for petroleum fractionation and biofuel purification.
- Precise reagent metering in reactive distillation reactors for esterification, transesterification, and alkylation studies.
- Supercritical fluid delivery (e.g., scCO₂) in extraction and particle formation experiments.
- Catalyst slurry injection in fixed-bed catalytic distillation units for hydrodesulfurization or Fischer–Tropsch modeling.
- Controlled solvent addition in foam extrusion trials for polymeric matrix development.
- High-pressure mobile phase delivery in preparative HPLC systems used for natural product isolation and chiral resolution.
FAQ
What is the maximum allowable inlet pressure for the JL0012?
The pump is designed for atmospheric or slightly pressurized inlet conditions; positive inlet pressure exceeding 0.2 MPa may compromise priming reliability and should be avoided unless using a dedicated pressurized solvent reservoir.
Can the JL0012 be operated in constant-pressure mode?
No—it is a constant-flow (volumetric displacement) pump. Pressure is a dependent variable governed by system resistance; active pressure regulation requires external pressure-control hardware or feedback-integrated system-level controllers.
Is firmware update support provided after purchase?
Yes—Sanotac releases periodic firmware updates addressing calibration refinements, communication protocol enhancements, and diagnostic improvements, available free of charge through registered customer portals.
Are replacement pump heads and seals available as spare parts?
Yes—10 mL stainless steel pump heads, sapphire check valves, PTFE piston seals, and ceramic plungers are stocked globally and ship within 3 business days of order confirmation.
Does the pump meet ISO/IEC 17025 calibration traceability requirements?
Calibration certificates issued by Sanotac’s CNAS-accredited metrology lab (Certificate No. CNAS LXXXXX) are available upon request and include uncertainty budgets referenced to NIST-traceable flow standards.
